Mike Hahn

Director of the Bowerman Sports Science Center, Professor of Human Physiology, and Associate Director of the Wu Tsai Human Performance Alliance

Mike Hahn is an academic expert in sports science and biomechanics. His research interests have ranged from prevention of falls, to utilization of computational analysis tools (such as artificial neural networks, support vector machines, and genetic algorithms) for solving complex modeling and optimization tasks, to enhancing the performance of fly-casting. He lead a study seeking to identify athletes with the highest risk of developing stress fractures, which can keep athletes out of competition for multiple seasons. The project was supported by a $1.2 million grant from the Pac-12 Conference Student-Athlete Health and Well-Being Initiative.

Current research projects are focused in the areas of prosthetic engineering, treatment outcomes in ankle osteoarthritis, neural control of powered prosthetic/orthotic devices, and mechanisms of locomotor adaptation after lower limb injury. Mike also teaches courses in biomechanics and capstone research.

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.

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.

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.
