Students use a variety of tools to conduct their summer research.

Summer fellowships awarded to exceptional science students

By Mary Hare

SURE Scholars use a variety of technology to fulfil their research goals, including light microscopes.

The College of Science is proud to announce that 41 science students – a record number – have received summer undergraduate research awards that will provide the opportunity and funding to pursue their research ambitions.

Undergraduate research often plays an instrumental role in developing student-faculty relationships that help students learn and grow beyond the scope of the classroom. For many OSU students, these awards provide the financial leverage to work in the field they are passionate about without being constrained to jobs that simply pay the bills.

The Summer Undergraduate Research Experience (SURE) award is available to all science students who meet the academic requirements. Participants are paid for 11 weeks of full-time research, or 440 hours, for a maximum of $5060. Awardees also receive an additional $500 for research expenses, including travel costs, materials or equipment rental.

This is also the second year that the Department of Integrative Biology offered the Alexei Lubchenco Menge Fellowship, which was awarded to Lily Miksell to support her research examining the interactions of dominant foundation species in Oregon rocky intertidal communities under the guidance of integrative biology professor Sally Hacker. The fellowship was established in memory of Alexei Lubchenco Menge, who died at age 27 in 2005. The award seeks to help one student each year within the department who exemplifies the deep love of the ocean that Lubchenco Menge personified.

SURE science awards are made possible by generous donations of College of Science alumni, faculty and supporters.

The COVID-19 pandemic has led to come changes in the SURE science program in 2020. Due to COVID-19 restrictions limiting access to laboratory space at Oregon State University, the deadline for completing SURE scholar research projects was extended to May 2021. Some students have projects that can be done entirely remotely and will complete and present their findings by the end of the summer. Some of the students below are able to work on their projects in OSU labs this summer, following OSU and Oregon Health Authority safety guidelines. For the majority of this year's awardees, the extended timeframe will allow them an opportunity to continue their research safely throughout the school year while gaining research experience.

Microbiologist Kim Halsey (left) and postdoc Cleo Davie-Martin collect samples from a river. Halsey is one of four faculty members who received College of Science Research and Innovation Seed (SciRIS-ii) awards. She will study the potential to detect toxic algae blooms in freshwater and marine ecosystems.

How can we better understand how devastating plant diseases are spread? Is there a better statistical model to predict HIV prevalence in a city? Is there a way we can detect toxic algae blooms in freshwater and marine ecosystems before they occur? And of the hundreds of thousands of different metal-organic frameworks (MOFs) in the world, how can we can better find the ones that are most useful for storing and separating gases, like CO2 from industrial plants?

Curiosity is critical for discovery. Asking the questions above led five faculty members to receive College of Science Research and Innovation Seed (SciRIS-ii) and Betty Wang Discovery Fund awards this February to pursue answers over the course of the next year. Their proposals all showed transformative potential and progress toward new frontiers of science and aimed to strengthen collaboration with external research partners. Below is more detail about each of their proposals.

Mathematics Professor Vrushali Bokil was awarded $8,000 to use modeling techniques to understand the spread and control of plant diseases caused by coinfecting viruses. She will focus on Maize Lethal Necrosis (MLN), an emerging disease in Kenya and other parts of Africa that is caused by coinfecting viruses and spread by insects called Thrips, as a test case. Her team’s goals are to use stochastic models and optimal control theory to understand the mechanisms that drive patterns of coinfection in plant populations and effective techniques for controlling the spread of disease in crops and natural grasslands.

In collaboration with the Centers for Disease Control and Prevention (CDC), Statistics Assistant Professor Katherine McLaughlin received $10,000 to explore the use of new statistical methodologies to estimate the number of people who inject drugs in metropolitan areas. The research project, supported by the privately-funded Disease Mechanism & Prevention Fund at the OSU Foundation, has a goal of refining current methods to produce improved population-level demographic, behavioral, disease prevalence and population size estimations. This will aid the CDC in their efforts to contain or slow the rate of HIV in metropolitan areas across the U.S.

Microbiologist Kimberly Halsey was awarded $10,000 to examine the potential for real-time, automated volatile organic compound (VOC) detection as early-warning signals of toxic harmful algal blooms (HABs) in freshwater and marine ecosystems. HABs are increasing in intensity and severity due to climate change and nutrient loading from agriculture and other human-related activities. Some HABs can become toxic to humans and animals. Halsey will use data integration to merge aquatic microbiome data with environmental properties and VOC signatures to identify determinants and trajectory of the annual toxic HAB at Upper Klamath Lake, Oregon.

Physicist David Roundy was also awarded $10,000 to develop new flat histogram Monte Carlo molecular simulation methods to accelerate the discovery of metal-organic frameworks (MOFs) for applications in storing and separating gases. MOFs are crystalline materials that harbor nano-sized pores that have the potential to be used in a variety of clean energy applications, from hydrogen and natural gas storage to capturing carbon dioxide from coal-fired power plant flues. His study aims to enable scientists to accurately predict the absorption properties of hundreds of thousands of MOFs and accelerate the rate of MOF discovery for clean energy applications.

In addition, chemistry professors Kyriakos Stylianou and May Nyman, along with Todd Miller from the Advanced Technology and Manufacturing Institute (ATAMI), received $30,000 from the Betty Wang Discovery Fund to purchase a microwave reactor to integrate on the continuous flow reactor to accelerate the discovery and production of inorganic materials like MOFs. The Betty Wang Discovery Fund supports equipment acquisitions and laboratory infrastructure improvements to advance fundamental discoveries in science. Microwave heating has recently emerged as a powerful method for the preparation of inorganic materials at the laboratory scale, reducing synthesis time down to a few minutes without affecting the product quality or reaction yield. The new machinery will allow the team to investigate the potential of new MOFs to capture carbon in laboratory and industrial applications.

The projects will run for one year, ending next February 2021.The SciRIS program provides funding in three stages for high impact collaborative proposals that build teams, pursue fundamental discoveries and create societal impact. The awards range from $10,000 to $125,000 for various stages of the program and are supported in part by generous alumni and friends, and grants from the U.S. Department of Defense and National Institutes of Health.

Synergies unleashed to tackle human health and disease

By Debbie Farris

The mysteries of human health and disease are as numerous as they are elusive. They pose complex problems that demand complex solutions. As science becomes increasingly interdisciplinary, the edges blurring and blending faster than we can name those evolutions, the challenges of human health require that we examine them from multiple perspectives, from biohealth, bioinformatics and biochemistry to chemistry, mathematics and biology.

In the 21st century, human health and disease require that we as scientists working in the life, physical and mathematical sciences collaborate. That we put our heads together, step outside the traditional academic boundaries to ignite new thinking and spur innovative solutions to address the most pressing problems in human health.

The proliferation of data is transforming the scientific landscape. Scientists are grappling with how to analyze and integrate data quickly across disciplines. With the mounting need for better, faster ways to harness vast amounts of information, mathematical and statistical researchers make for natural partners who are well trained to manage and interpret data to deepen understanding of the scale of health issues. This approach enables scientists to test more theories and manage more data to develop a greater, more sophisticated understanding of human health.

This fall the National Science Foundation’s Division of Mathematical Sciences and the National Institutes of Health’s National Library of Medicine launched a Joint Initiative on Generalizable Data Science Methods for Biomedical Research to support the development of innovative and transformative mathematical and statistical approaches to address data-driven biomedical and health challenges.

OSU researchers are harnessing the power of global collaborations to deepen understanding of and to address our most important concerns in human health.

The chemistry behind aging

Biophysicist Elisar Barbar and team discovered that the intrinsically disordered state of the protein ASCIZ, a key transcription factor in cells, plays a major role in regulating production of the protein LC8, a hub protein regulating over 100 other proteins critical to a wide range of life processes from viral infection to tumor suppression to cell death. Her work on intrinsically disorganized proteins, a hot frontier of research in biochemical and medical research today, has far-reaching implications due to their critical role in a vast array of cellular functions.

Colleagues Afua Nyarko and Viviana Perez are studying the chemistry behind the biological processes and the synthesis of biologically active molecules. Nyarko studies protein interactions and their role in the formation of tumors. She is one of a handful of scientists worldwide studying proteins from a structural biology perspective, where detailed information on the structure of specific amino acids can reveal how tumor suppressor proteins inhibit specific growth-promoting proteins.

Perez studies the biological processes of aging, specifically the protein aggregation in neurodegenerative diseases and protein misfolding. She discovered a new function for the compound rapamycin that, with its unusual properties, may help address neurologic damage.

Barbar and Nyarko’s work uses nuclear magnetic resonance to describe molecular structures of proteins. They also focus on protein informatics, from the analysis of experimental mass-spectrometry evidence for proteins to the integration and curation of large-scale data warehouses of protein sequence and functional annotation.

Genetics and bioinformatics

Our bioinformatics researchers are working on groundbreaking developments at the nexus of data science and human health. David Hendrix developed a neural network program that illuminates connections between mutant genetic material and disease. His team used deep learning to decipher which ribonucleic acids (RNA) have the potential to encode proteins, an important step toward better understanding RNA, one of life’s fundamental, essential molecules. Unlocking the mysteries of RNA means knowing its connections to human health and disease.

Hendrix compares it to a tool similar to calculus or linear algebra, but one used to learn biological patterns. Deep learning is helping his team manage vast amounts of data and learn new biological rules that distinguish the function of these types of molecules. He recently teamed up with the Barbar group to develop an algorithm that will predict new proteins that interact with LC8. This validates the importance of LC8 in many systems and opens up new interactions to study, underscoring the power of big data to guide new experiments.

David Koslicki recently discovered that the blood of patients with schizophrenia features genetic material from more types of microorganisms than the blood of people without the debilitating mental illness. His team performed whole-blood transcriptome analyses on 192 people, including healthy people and people with schizophrenia, bipolar disorder and Lou Gehrig’s disease. The findings showed that microbiota in the blood are similar to ones in the mouth and gut. There appears to be some permeability there into the bloodstream.

Koslicki and his collaborators received an NIH grant to build a biomedical translator, a software system that connects various distributed databases of biomedical knowledge and that can “reason” over these data sources to answer relevant biomedical questions. This is one example of how mathematical and computational sciences are syncing with biomedical research to accelerate translation for the scientific community.

Fighting disease

Microbiologist Bruce Geller scored a monumental win against antibiotic resistance. He crafted a compound known as a PPMO that genetically neutralizes a pathogen’s ability to thwart antibiotics. His team designed and tested PPMOs against Klebsiella pneumonia, an opportunistic pathogen that’s difficult to kill and resistant to many antibiotics. A platform technology, PPMOs can be quickly designed or modified to kill nearly any bacterium. They are not found in nature so bacteria have not developed resistance to them. PPMOs may be highly effective therapeutics.

Geller expects that the wave of the future will be molecular medicine, a broad field that draws on physical, chemical, biological, bioinformatics and medical techniques to describe molecular structures and mechanisms, identify molecular and genetic errors of disease and develop interventions. OSU scientists are combining these experimental and mathematical tools to develop anti-viral drugs.

Microbiologist Thomas Sharpton made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other mammals evolve. His global team created a new algorithm and software to taxonomize and clarify key microbial clades, or groups of microbes that appear frequently across mammalian species. A Western lifestyle tends to reduce microbial diversity so knowing which clades have been evolutionarily conserved opens up potential health interventions.

Statistical innovations help decode the human microbiome

Gut Microbiota

The human microbiome—the vast collection of microorganisms living in and on the bodies of humans—can lead us to a better understanding of human health and disease, not to mention accelerate the development of therapeutic drugs. However, the vastness and complexity of microbiome data require advances in statistical methodology and software for an accurate analysis of host-microbiome interactions. Statistics faculty Yuan Jiang, Duo Jiang and Thomas Sharpton are developing novel statistical methods to bridge the gap between the human microbiome and microbiome-based healthcare.

They were awarded a prestigious four-year $770K grant by the National Institute of General Medical Sciences (NIGMS), one of the U.S. National Institutes of Health (NIH). Yuan Jiang, associate professor of statistics, is the lead researcher and principal investigator on the project, “Network-based statistical methods to decode interactions within microbiomes.” Duo Jiang, assistant professor of statistics and Thomas Sharpton, assistant professor of microbiology and statistics, are co-investigators on this grant.

This project will advance scientific understanding of the functions and operations of microbiomes by developing statistical methods and models to study biological interactions between microbes or between microbes and their host.

“The new statistical methodologies will leverage recent advances in graphical models and high dimensional statistics to tackle unmet analytical challenges encountered in the analysis of modern microbiome data,” said Duo Jiang.

Interest in the role of the microbiome in human health and disease has increased rapidly within the last decade. However, available tools and technologies do not adequately capture the full scope and complexities of microbial interactions within a community. For example, a correlation type analysis employed to model microbial interactions cannot filter out misleading co-occurrence patterns in a community: two microbes that independently interact with a third but not with one another may appear to correlate.

“The currently used statistical models fail to account for specific properties of microbiome data, including its heterogeneous compositional count nature, the complex environmental context, and its evolutionary structure,” Yuan Jiang explained.

“Additionally, existing algorithms are often not scalable to the huge size of microbiome data. Therefore, new statistical methods and algorithms need to be developed to better answer the scientific questions.”

The NIGMS grant will help Jiang and his team pioneer new statistical methods “built on conditional dependencies that disentangle biological interactions from marginal correlations to produce mechanistically and evolutionarily relevant network models of how microbes interact with one another and their host.”

The methods and software produced by this project will “transform the discovery of how these microbes interact with one another and influence or respond to human physiology.” A broader understanding of microbiomes and their role in disease etiology will open the doors to engineer and utilize microbiomes important to human health to develop new drugs, therapeutic probiotics and clinical diagnostics.

The grant will support graduate research assistants (GRAs). Two GRAs from statistics and one GRA from microbiology will be a part of this interdisciplinary collaboration. “Such a form provides students with opportunities for experiential learning in diverse scientific areas (e.g., statistics, computer science, microbiology, evolution, and genetics) as well as experience in teamwork and interdisciplinary research,” said Yuan Jiang.

150 years of science for land and sun

By Katharine de Baun, Srila Nayak

Painted Hills, Oregon

Note: this article is part of a yearlong series on the distinguished tradition of scientific research pertaining to Oregon State’s 150th anniversary and its four land-grant designations. From our fall 2017 issue: 150 years of science for sea and space(Introduction), On the shoulders of giants, Oregon State Science: The many "firsts" in 150 years. From our spring 2018 issue: The significance of OSU's sea-, space-, sun- and land-grant designations, "Milestones: Oregon State Science at the helm for 150 years."

While the College of Science at Oregon State University was formally established in 1932, science programs and departments have been instrumental in shaping the evolution of research and education at the university since its 1868 land grant designation.

In fact, long before OSU’s College of Agricultural Sciences came into existence, the new agricultural curriculum was first taught in the Department of Chemistry in 1870 paving the way for the scientific study of agriculture for the first time in the Pacific Northwest. Such pioneering science programs since the earliest days of the institution were responsible for OSU’s land grant designation making it one of three land-grant colleges in the country at that time (The other two were the University of Illinois at Urbana-Champaign and the University of California at Berkeley).

The first professors of engineering at OSU in the 1890s were also professors of mathematics. Some of the university’s earliest engineering disciplines would not have flourished if it were not for the fundamental sciences. A four-year mining engineering curriculum was established in the Department of Chemistry in 1900 that led to the consolidation of early engineering programs in metallurgy.

The chemistry department was also the home of the first geology courses. It would not be an exaggeration to say that the natural and physical sciences at OSU have shaped and guided the growth of the world-class research and education that takes place across all STEM (science, technology, engineering and mathematics) fields in the university today.

OSU land grant: From plows to touch screens

Science has played a founding role in carrying out Oregon State’s Land Grant mission from its origins in the Morrill Act of 1862, whose focus was to teach agriculture, military tactics and “mechanical arts” or engineering. Chemistry was hailed, for example, as “the cornerstone of Scientific Agriculture” in the 1869-70 course catalog. And in 1899, today’s microbiology department arguably began with a single course in bacteriology, to help understand and eliminate bacterial diseases of crops. Mathematics and physics courses were a core part of the mechanical arts curriculum and the fledgling department of mechanical engineering, formed in 1889.

In the 20th century, the University’s land-grant mission expanded to adapt to the changing social and economic needs, including a new forestry program in response to Oregon’s growing timber industry and a growing emphasis on engineering after World War II. As the scope of the land-grant mission widened, science continued to be front and center. The chemistry department was home to new four-year programs in pharmacy (1898), mining (1900) and forestry (1906). By 1912, bacteriology was driving innovation across various industries and considered essential training for “any student properly equipped in Dairying, Agriculture, Agronomy, Pharmacy, Domestic Science, etc.”

In the 21st century, Oregon State under President Ray’s leadership aims to be among the top 10 land grant institutions in America, with a focus on three signature areas: the Science of Sustainable Earth Ecosystems, Human Health and Wellness, and Economic Growth and Social Progress. The College of Science is a key contributor with pioneering programs and research in biohealth, the life sciences, marine and environmental sciences and, increasingly, statistics, as students and researchers across a wide variety of fields learn to interpret and gain often revolutionary insights from big data.

An integral part of OSU’s land-grant mission is also to foster public outreach and engagement, and science has long been at the heart of its various agricultural experiment stations and Cooperative Extension Service. Through evidence-based programs designed to make Oregon farms more sustainable, to teach gardeners how to raise bees, reduce pesticides or compost; or encourage children to pursue STEM careers through its engaging, hands-on 4-H programs — science provides both a body of evidence and a mode of inquiry that supports both backyard sleuths and future astrophysicists.

Science also contributes to economic growth with a constant stream of research-inspired innovation, producing 48 new inventions and securing 18 U.S. patents since 2011 alone. Local, state and global industries have profited from sustainable materials that began as lab experiments in Gilbert Hall, from more efficient batteries and greener touch screens, to a new heat-resistant paint using YImMn blue, the new pigment discovered by chemist Mas Subramanian.

Lastly, the College’s current investment in student diversity and success continues a long and proud tradition of opening STEM fields to all, science being a necessary part of the “liberal and practical education” for the “industrial classes” since the passage of the 1862 Morrill Act. As the University’s land-grant mission continues to evolve, science will remain at the heart – and the edge – of discovery and innovation.

Sun: Harnessing natural resources for a healthy planet

For nearly 150 years, the natural sciences at OSU have been at the forefront of research and innovation bridging the biological sciences and the physical sciences (physics and chemistry) for environmental sustainability, renewable energy and a healthy planet.

Chemist David Ji has pioneered the invention of new long-lasting and high-performance energy materials in the form of batteries for the purposes of sustainable energy storage. By employing carbon-based materials and hydrocarbon solids, Ji has designed new battery devices such as the world’s first hydronium-ion battery, potassium-ion battery, dual-ion battery and sodium-ion battery which can easily and cheaply store energy from the wind and sun. Ji’s innovations in the area of energy storage have ushered in a new era of renewable and sustainable batteries.

Materials physicist Janet Tate is a key player in the field of renewable energy technologies that includes development of transparent conductors and photovoltaic materials. Tate is a principal investigator at the prestigious Center for Next Generation of Materials Design—an Energy Frontier Research Center (EFRC) funded by the U.S. Department of Energy.

By integrating the talent and expertise of leading scientists such as Tate, the EFRC aims to “accelerate transformative discovery” and innovate new materials on the atomic and molecular scale to enhance energy security and protect the global environment. At the Center for Next Generation of Materials Design, Tate studies metastable alloys to design inorganic semiconductors for optoelectronic applications (electronic devices that source, detect and control light).

The OSU Sun Grant program is supported by funds from the U.S. Department of Agriculture and the Department of Energy aimed at the creation of biofuels and other environmentally sustainable green technologies to meet growing energy demands and promote opportunities for bio-based economic growth in rural communities.

One of the key sun grant projects on genetic modification of poplar trees to produce plant-based plastics will be extended in new, innovative directions with the added expertise of statistical methods. In collaboration with College of Forestry Professor Steven Strauss, statistician Yuan Jiang is investigating better methods of mapping the genes that control the process of regeneration and transformation needed for genetic engineering by using DNA sequence databases, imaging and computations.

This five-year, $4 million project is funded by the National Science Foundation and is an important advance in developing genetically engineered crop species in ways that help meet our present challenges without unintended environmental effects.

From the lab to the world: OMSI Science Communication Fellowships

The OMSI Science Communication Fellowship Program

Applications are open for Oregon's top academic and professional fellowship program: The Oregon Museum of Science and Industry's OMSI Science Communication Fellowship. For spring 2018, the fellowship is open to researchers or science professionals including faculty, graduate students, technicians, or other individuals in STEM and health related professions.

The deadline for applications is Wednesday, November 1.

Held primarily in Corvallis, OR on the OSU campus, OMSI Fellows participate in a series of professional development workshops that cover science communication best practices and provide opportunities for participants to practice new skills and techniques. In collaboration with OMSI, each Fellow will develop a unique hands-on educational activity designed to communicate their research to public audiences and will join OMSI in engaging museum visitors with these activities at Meet a Scientist events.

A series of four professional development workshops will focus on building skills to effectively communicate scientific research with broader audiences. Workshops are 3-4 hours each, spaced over the course of three to four months.

Tuition for the program is $1850 per participant. The Science Dean's Office will cover half the tuition for all accepted College of Science applicants.

The OMSI Science Communication Fellowship Program is an excellent way to fulfill broader impact and outreach goals for grant-funded research at OSU. Many of the participants in the Fellowship program secure their tuition through broader impacts or education and outreach components of current research grants.

An online application and further information about the Fellowship program can be found on OMSI's website.
