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.

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.

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.

Moderated by Dr. Lesley Jo Weaver (UO), Associate Professor at the University of Oregon and co-director of the Homelessness Policy and Health Research Group

UCLA sociologist Chris Herring’s research focuses on poverty, homelessness, and housing in US cities. His current book project is an ethnography of the criminalization of homelessness in San Francisco to be published with UC Press.  He has co-directed two participatory action research projects and publications with the San Francisco Coalition on Homelessness, where he organized with the Human Rights Working Group. Herring served as a researcher at the San Francisco’s Mayor’s Office of Homelessness and has collaborated on research with the National Coalition on Homelessness, Anti-Eviction Mapping Project, the Western Regional Advocacy Project, and ACORN. He regularly consults with county governments, think tanks, and legal aid groups.

Herring’s writing has appeared in the Washington Post, Places, Progressive Planning, Shelterforce, the Berkeley Journal of Sociology, and homeless street newspapers across the US and Canada. His research and commentary has also been featured in the LA Times, NY Times, UK Guardian, Al Jazeera, the San Francisco Chronicle, Bloomberg’s City Lab, and other outlets.

UO Professor Claire Herbert's research focuses on law, housing, property, and urban sociology. Her book, A Detroit Story: Urban Decline and the Rise of Property Informality was published with University of California Press in 2021. In this book, she examines the way that de jure illegal uses of property - like squatting, scrapping, and gardening - shape the form of the city, neighborhood conditions, and residents’ well being.

Professor Herbert is currently writing a book called When Home is Illegal: Unsheltered Homelessness in America which examines the interaction between local regulations, enforcement, and the well-being of residents experiencing unsheltered homelessness. Professor Herbert is also Co-PI on an NSF-funded, mixed-methods project called "Informality and Inequality in the Global North: Regulation, Non-Compliance, and Enforcement in US Land Use and Housing Law" which studies informal infill: housing units produced in violation of local regulations but that provide an important source of affordable housing.
