World-Class Faculty in the Natural Sciences
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 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.

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.

The Department of History is pleased to welcome Estelle Freedman, Edgar E. Robinson Professor in U.S. History (Emerit) at Stanford University and co-founder of Stanford’s Program in Feminist, Gender, and Sexuality Studies, for the 2026 Pierson Lecture: "Speaking of Sexual Violence: Voices from Women’s Oral Histories in the Twentieth Century U.S."
How can historical research contribute to understanding silence and speech about sexual violence? Based on her analysis of a large text database of oral history collections, Professor Freedman will explore how women from diverse backgrounds remembered and reacted to unwanted sexual advances during the twentieth century. She applies both quantitative digital humanities tools and qualitative close readings of relevant women’s narratives to consider two topics: stories of sexual assault handed down in African American families, and varied responses to educational and workplace harassment.
Freedman is the Edgar E. Robinson Professor in U.S. History (Emerit) at Stanford University and co-founder of Stanford’s Program in Feminist, Gender, and Sexuality Studies. She is the recipient of fellowships from the National Endowment for the Humanities, the Guggenheim Memorial Foundation, and the Center for Advanced Study in Behavioral Sciences, where she is currently a Stanford Faculty Fellow. Freedman’s ten books on the histories of women, feminism, and sexuality include two prize-winning studies of prison reform--Their Sisters' Keepers and Maternal Justice; the surveys No Turning Back: The History of Feminism and the Future of Women and (with John D'Emilio) Intimate Matters: A History of Sexuality in America; and the multi-award winning Redefining Rape: Sexual Violence in the Era of Suffrage and Segregation. She is currently writing about narratives of sexual assault and harassment in 20th century women’s oral histories. Freedman co-directed (with Christie Herring) the 2024 documentary film, Singing for Justice, about S.F. Bay Area folk musician and political activist Faith Petric (1915-2013).
The Annual Pierson Lecture is a Department of History tradition that spans back to 1993, when it was founded to honor Stan and Joan Pierson. The Piersons were both exemplary citizens of the community, dedicated to history and education as proven by their distinguished records of intellectual accomplishment and community involvement. This lecture series brings distinguished scholars to the University of Oregon, so that they may share their work in alignment with the Piersons’ interests in cultural, intellectual, and political life.
