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.

Mapping the Motor System with Brain Stimulation
October 12–14

The Action Control Laboratory at University of Oregon (headed by Ian Greenhouse) and scientists from the Germany-based Max Planck Institute, which carries out basic research in the life sciences, natural sciences, and the social and human sciences—are collaborating in the area of transcranial magnetic stimulation (TMS) brain mapping with particular emphasis on the sensori-motor cortex. A neuroscience conference held at the UO in October 2026 will provide the occasion to discuss collaborative research opportunities and develop grant proposal ideas 

The Action Control Lab is in the Department of Human Physiology at the UO. This lab studies how the brain controls movement. For example, how do humans initiate and cancel prepared movements, and what underlies variability in our actions? To answer these types of questions, scientists use a combination of behavioural testing, electrophysiology, brain stimulation, and neuroimaging methods. They study both healthy individuals and patients with movement disorders.  

The MPI group has developed and is developing sophisticated algorithms for precise TMS-based brain mapping, while the Oregon group applies those techniques to their research on the neural computations for human action control. This work has basic science and clinical relevance.

This event is part of International Education Month (IEM) programming. View the full calendar of IEM events here: https://international.uoregon.edu/IEM.

Eco-Fascism Lecture Series: "Bread from Air: Nitrogen Capture and the Atmospheric Imagination in Fascist Italy"
October 13
4:00 p.m.

Environmental concerns—from nature conservation to air and water quality—are often associated with progressive politics. But under Fascisms past and present, ecological ideas have also animated authoritarian projects. This speaker series examines how dictatorships mobilize nature as both metaphor and material resource. As a metaphor, agrarianism evokes Fascism’s foundational mythos: the dictator will restore the country’s glorious national past. To live a rural, old-fashioned lifestyle was to be a more patriotic citizen. “Italy must be ruralized!” proclaimed Benito Mussolini in 1927. As a material resource, nature is often put to use in service of eugenics and racial hygiene.

Our speakers will examine the professional biographies of the scientists, industrialists, and entrepreneurs hired by Fascist regimes to determine the limits of biological possibility. Case studies from empire and the colonies will investigate the Fascist programs for experimental plant nurseries, animal breeding, and chemical trials. Rather than treating eco-fascism as a contradiction in terms, our speakers will situate it within longer histories of environmental planning, population management, and technocratic governance. They will explain how dictatorships use the tools of authoritarian governance to modify the environment in their pursuit of more Fascist futures.

Please join us for these illuminating discussions.

Talk details:

Bread from Air: Nitrogen Capture and the Atmospheric Imagination in Fascist Italy

Speaker: Prof. Rebecca Falkoff, University of Texas, Austin

At the end of the nineteenth century, nitrogen, the seventh most abundant element in the galaxy, became the focus of a discourse of scarcity. Essential to the material composition of all life, nitrogen came to seem scarce as demand increased for two classes of compounds that fueled modern life: fertilizers and explosives. The nitrogen problem, as it came to be known, seemed to have an obvious solution: a limitless supply of nitrogen would be available if the nitrogen gas (N₂) that composes roughly 78% of the atmosphere could be "captured" and "fixed" to other elements. Although that solution posed a scientific challenge, since nitrogen gas is unreactive, the very possibility—and then its realization—transformed the sky into a new frontier, promising agricultural and industrial productivity and military power. Nitrogen capture engendered fantasies of economic revival and social and cultural renewal.

In her talk, Falkoff will show how these fantasies, and the nitrogen-capture industry that grew alongside them, became central to fascist ideology—animating the belief that Italian genius could transform scarcity into abundance, and shaping initiatives from the Battle for Wheat to the Battle for Births, economic autarky, and imperial expansion. Charting nitrogen discourse across speeches, advertising, technical writing, and futurist works in paint, ceramic, and prose—from Montecatini's campaigns to the essays of novelist-engineer Carlo Emilio Gadda—she traces how nitrogen staged the tensions central to Italian fascism: between materialism and vitalism, global circulation and national appropriation, the organic and the inorganic, labor and magic, intervention in natural cycles and creation ex nihilo.
