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.

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.

Latine Worldmaking: Queer Ecologies, Migration, and Belonging
April 16
3:30–5:00 p.m.
Erb Memorial Union (EMU) Crater Lake South

The Center for Latino/a and Latin American Studies (CLLAS) is pleased to host a research colloquium featuring faculty and graduate student scholars whose work explores how migration, embodiment, environment, and cultural production shape Latine experiences of belonging. Through literature, media, performance, and critical theory, this event highlights interdisciplinary approaches to identity, place, and community across Latinx and Latin American contexts.

Salomé Herrera, PhD, is a faculty member in the Department of English at the University of Oregon whose research is rooted in literary, performance, and Latinx studies. In their talk, "Trans* Epistemologies: Tracing the Womb across the Gloria Evangelina Anzaldúa Papers," Herrera traces an embodied trans* epistemology across the Gloria Evangelina Anzaldúa Papers from the Benson Library at the University of Texas at Austin. They specifically examine the development of Anzaldúa’s conceptualization of “el cenote,” Mexican lime hole sinkholes with spiritual significance for Mayan cultures, understood as material reservoirs or “wombs” of the collective unconscious from which creativity emerges. Drawing across spiritual and materialist traditions, Herrera shows how a sense of transitivity emerges from a queer Chicana feminist understanding of evolution, ultimately arguing that Anzaldúa’s speculative world-building transforms the womb from a colonized site of carceral policing into one of communal creativity with decolonial potential.

Alejandro Marín is a doctoral candidate in the Department of Romance Languages at the UO whose research focuses on contemporary migrant narratives from Cuba, the Dominican Republic, and Equatorial Guinea. His dissertation, "The New Errancy: Configurations of Contemporary Migrant Literature in Cuba, the Dominican Republic, and Equatorial Guinea," develops “The New Errancy” as an analytical category to examine how authors from three distinct migration contexts challenge traditional colonial axes, reimagine non-biological family formations, and construct transnational identities in solidarity with contemporary migrants. Supported by the CLLAS Graduate Research Grant, Marín conducted archival research in the Dominican Republic, interviewed author José Acosta, and observed cross-border dynamics at Dajabón, grounding his work in lived migration contexts. The chapter he presents reads Loida Maritza Pérez’s Geographies of Home as a meditation on how transnational Dominican families negotiate generational fracture, linguistic displacement, and the contested meaning of belonging between the island and the United States.

Moe Gámez is a doctoral student in the Department of English at the UO whose research explores the intersection of Latinx literature, environmental justice, and queer/trans theory. Their dissertation examines how queer and trans Latinx authors and artists represent ecologies through embodied, speculative, and political narratives. Through archival and literary analysis, Gámez’s work contributes to the growing subfield of queer and trans Latinx environmentalisms, highlighting how questions of environment, identity, and embodiment are deeply interconnected.

Together, these scholars offer interdisciplinary perspectives on how Latine communities and cultural producers negotiate identity, space, embodiment, and belonging in relation to migration, ecology, and social transformation. Please join us for this engaging conversation and opportunity to learn more about emerging faculty and graduate student research at the UO. This event is presented by the Center for Latino/a and Latin American Studies.

NW-NALRC Community Project Planning and Development Workshops
April 1–30
3:30–4:30 p.m.

The Northwest Native American Language Resource Center's Community Project Planning and Development (CPPD) workshops are designed to help guide you through the process of creating a community-based project: from coming up with the idea, to building a solid organizational and logistical foundation, and all of the other necessary steps to get your project proposal completed. Overall, there are 15 CPPD workshops in this series

Each workshop also has an associated next-day drop-in assistance hour. This workshop series is meant to take participants with little to no experience in community project planning and development and help them complete their first project proposal. While we are focused on assisting with project planning and development of Alaskan Native/Native American Language projects, much of the content that you will be learning in these workshops is readily transferrable to other types of projects.

Registrants will have access to all workshops in this April offering. Attendance at all workshops in the offering is recommended but not required. 

All instruction is provided online and instructors will join online. Participants will join remotely via zoom (please see technology section below.)

Workshops in this Offering

The CPPD workshops are offered in smaller, five workshop offerings. The first five workshops were offered in November and December of 2025. The workshops that are available in the April offering are: 

Workshop 6: Identifying Long-Range Goals 

  • Topic: Supports facilitation of community discussions to identify vision-aligned, long-term goals that drive project outcomes.
  • Date: 4/1
  • Drop-In Assistance: 4/2

Workshop 7: Defining Barriers to Long-Range Goals 

  • Topic: Identifies internal and external barriers, explores strategies to surface challenges, and begin problem-solving approaches.
  • Date: 4/8
  • Drop-In Assistance: 4/9

Workshop 8: Creating Project Goals & Objectives 

  • Topic: Translates community vision into specific, measurable project goals and objectives using clear, structured frameworks.
  • Date: 4/15
  • Drop-In Assistance: 4/16 

Workshop 9: Outcomes, Outputs, & Activities 

  • Topic: Distinguishes outcomes, outputs, and activities, aligns them within a project framework/logic model.
  • Date: 4/22
  • Drop-In Assistance: 4/23

Workshop 10: Building a Project Work Plan

  • Topic: Hands-on strategies to create a work plan with timelines, milestones, responsibilities, and deliverables.
  • Date: 4/29
  • Drop-In Assistance: 4/30

Technology

The CPPD workshops will be held via Zoom and will use Canvas, a course management system, for materials and activities. Participants must have an email address. It will be best to join on a computer that has a stable internet connection, a webcam, and headphones (depending on your work environment). Using a computer rather than a mobile device will improve your experience - you will be able to better  interact with others, participate in hands-on activities, and see presented materials.
