Our science departments are committed to creating and disseminating new knowledge in their fields by combining research and teaching. Our 300 faculty members—including fellows of many learned societies and academies—are engaged in research that spans a broad range, from questions about the foundations of quantum mechanics, to the development of cancer cells and the workings of the brain, to work resulting in the spin-off of high-technology companies. Faculty share their excitement about their research with their students, training them to become part of the next generation of scientists who will push the frontiers of human knowledge.

News from Natural Sciences

HUMAN PHYSIOLOGY - For Graduate-Professional Student Appreciation Week in 2026, CAS gradate students share their experiences of what makes their experience special at CAS. CAS is home to 1,295 graduate students: 307 master’s and 959 PhD. With April 6-10 Graduate-Professional Student Appreciation Week, CAS reached out to some of its graduate students to hear how about their experiences at the college.
HUMAN PHYSIOLOGY - John Halliwill has been named a 2025 fellow by the American Association for the Advancement of Science (AAAS). A professor in the Department of Human Physiology, Halliwill was recognized for advancing the understanding of exercise-induced cardiovascular adaptation and discovering histamine's role as a signaling molecule in adaptation to physical activity.
CHEMISTRY, BIOCHEMISTRY — A hands-on experience is essential to study chemistry, and labs are how students apply what they’re learning in lecture. But many students experience anxiety before entering labs so Associate Professor Cathy Wong set out to make labs more accessible and more fun.

World-Class Faculty in the Natural Sciences

Thien Nguyen, Associate Professor of Computer Science

Thien Nguyen

Associate Professor of Computer Science

Thien Nguyen is an expert in natural language processing, or the ability of artificial intelligence to understand, interpret and generate meaningful human language. He aims to enable computers to perform cognitive language-related tasks. His lab is among the first to develop deep learning algorithms for information extraction and text mining in natural language processing and data mining. His research on using natural language processing for multilingual learning earned him a Faculty Early Career Development Program (CAREER) award from the National Science Foundation.

Nguyen's recent research focuses on programming computers to improve the efficiency and safety of large language models (LLMs) across human languages while extracting valuable information about events like natural disasters, cyberattacks, disease outbreaks, and protests from news articles and other sources. His work seeks to deliver useful insights from diverse data and make these technologies accessible in low-resource languages that lack adequate data sets for training AI models.

Tien-Tien Yu

Associate Professor of Physics, Institute for Fundamental Science

Tien-Tien is a theoretical particle physicist working at the interface of theory and experiment. She is particularly interested in understanding the nature of dark matter, whose existence is known through its gravitational effects on ordinary matter. She co-founded the SENSEI collaboration, an experiment utilizing silicon chips, much like those found in digital cameras, to search for dark matter. She was recently appointed to P5, an advisory group convened once a decade by the Department of Energy and National Science Foundation to help determine the next funded projects in particle physics.

On Jan. 14, 2025, Yu was one of nearly 400 scientists and engineers to receive the Presidential Early Career Award for Scientists and Engineers, the highest award the US government awards to early career scientists. 

A founding member of the group Particles for Justice, Yu is also a leader in advancing diversity, equity and inclusion in the physics field. In collaboration with the Comics and Cartoon Studies program, Yu created the UO Science and Comics Initiative. Read more about the initiative here.

Santiago Jaramillo, Associate Professor of Biology, Institute of Neuroscience

Santiago Jaramillo

Associate Professor of Biology, Institute of Neuroscience

Santiago Jaramillo leads a research group dedicated to understanding how the brain processes and interprets sounds. Using advanced techniques to monitor and manipulate neural activity in mice, along with computational approaches, he investigates how the brain filters, learns, and assigns meaning to sounds and how brain disorders can affect these processes. His interdisciplinary work, supported by the BRAIN Initiative of the National Institutes of Health and the National Science Foundation, includes collaborations with psychologists, bioengineers, theoretical neuroscientists, and linguists, with the long-term goal of developing neural interfaces to improve human-to-human and human-to-machine communication.

Beyond the lab, Jaramillo is deeply committed to broadening participation in STEM. He provides hands-on neuroscience experiences to middle school girls through the SPICE program, serves as an advisor for international programs engaging young minds in scientific critical thinking, and mentors college students from a wide range of backgrounds through programs such as NSF STEP-UP, SPUR, and the ESPRIT scholarship for aspiring K-12 science teachers. 

 

 

The new School of Computer and Data Sciences will be open in fall 2023 to students throughout the UO, with the goal of serving 2,000 undergraduate majors and students in existing and new undergraduate and graduate programs.

School of Computer and Data Sciences

The mission at SCDS is to empower a diverse population of students and faculty working to advance knowledge in computer and data science, train the next generation of scholars, and engage with the wider world to tackle interdisciplinary challenges.

To do this, we start by applying our knowledge and experience at home across the University of Oregon campus.

Research in the Natural Sciences

Natural scientists use data to understand, predict, and work with naturally occurring phenomena on earth and in the universe. From highly controlled experiments in the lab to observations collected in the field, our findings help make sense of the natural world while driving advancements in society and technology that touch everyone. By expanding the limits of human knowledge, we provide a scientific foundation for helping people live better, longer lives.

2024-2025 Sponsored Research in Natural Sciences

Between July 2024 and June 2025, researchers in CAS received $83 million to fund 199 research projects, including approximately $75 million in Natural Sciences. The research projects, which span divisions and fields of study, represent CAS's commitment to curiosity, discovery, and innovation.

Meet our Dean

Welcome to the natural sciences, where our top-flight researchers bring students in to experience the biological, physical, and computational sciences. Working side-by-side with faculty who are equally committed to student success and scientific discovery, students learn valuable critical thinking skills through hands-on research in the lab, field, and classroom—from studying marine biology at the Oregon Institute for Marine Biology on our beautiful campus on the coast to coding advanced systems and analyzing complex data in the School of Computer and Data Science.

The research we’re conducting at the UO makes a tangible difference in our communities, our nation, and the world. For example, our chemists are pioneering the materials and techniques that will inspire the next generation of batteries for energy storage. Our psychologists are developing and testing cutting-edge interventions to improve mental health and wellbeing. Our geologists and environmental scientists are collaborating with governments, tribes, and industry partners to protect communities from earthquakes and wildfires.

You may or may not end up in a science career, but either way these experiences will change the way you experience and interact with the world. A healthy society depends on people who know how to gather evidence and critically analyze data. No matter what field you enter, scientific thinking will help you become a more thoughtful, engaged, and critical citizen in modern society.

We’re excited to explore the natural world with you.
