CAS Researcher Receives High Award 
from White House

College of Arts and Sciences researcher Tien-Tien Yu is among nearly 400 scientists and engineers awarded the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the US government on outstanding scientists and engineers early in their careers. 

Yu is an associate professor in the Department of Physics and a member of the Institute for Fundamental Science. Her work is focused on dark matter, and she is the co-creator of the UO Science and Comics Initiative to make science more engaging and fun. 

“I am honored to receive the PECASE for my work as it highlights both the critical role of fundamental science and the importance of making such research accessible,” Yu said. “Curiosity-driven research, such as uncovering the nature of dark matter, lays the groundwork for discoveries and breakthroughs that shape our world. I am excited to see where this research leads and how it can inspire future generations.”

News from CAS

BIOLOGY, PHYSICS - A new study published in the journal mBio shows how one kind of bacteria, Vibrio cholerae, triggers those painful contractions by activating the immune system. The research also finds a more general explanation for how the gut rids itself of unwanted intruders, which could also help scientists better understand chronic conditions like inflammatory bowel disease. The research was led by Julia Ngo, a now-graduated doctoral student in Karen Guillemin and Raghu Parthasarathy’s labs.
ECONOMICS - Increased exposure to glyphosate, one of the most widely used herbicides in the United States and much of the world, harms infant health in agricultural counties, according to a new study by two University of Oregon economists Emmett Reynier and Edward Rubin. The two published the findings in the Proceedings of the National Academy of Sciences.

Meet our Dean

In the College of Arts and Sciences (CAS), we are committed to excellence in research and teaching, student success, and diversity, equity, and belonging. 

A liberal arts education—one that offers a breadth of intellectual approaches and perspectives and depth in a major discipline—is the foundation to a purposeful life as a life-long learner, engaged citizen, and leader. The skills you will learn here—from written and verbal communication to analytical and quantitative reasoning, to compassion and understanding—are those that employers seek and will open the door to a wealth of opportunities. 

You will find more than 50 majors and a multitude of minors within CAS, and seemingly endless opportunities for personal exploration and discovery. Whether you are an incoming first-year student, a grad student or a transfer student, you can map an exciting future and be part of a fun, warm, engaged liberal arts community here. Come join us. And go Ducks!

Title: On-Demand Control of Single-Molecule Chemistry through Vibrational Characterization and Manipulation

Chemical processes hinge on the dynamic rearrangement of nuclei within molecules. Controlling these motions with precision has been a long-standing goal in chemistry. My lab focuses on achieving this by manipulating interactions between individual molecules and their nanoscale environment. We engineer the potential energy surface at this scale to control molecular properties such as structure and reactivity. Using vibrational characterization techniques with scanning tunneling microscopy (STM)—including inelastic electron tunneling spectroscopy, action spectroscopy, and our recent advancement in single-molecule infrared absorption spectroscopy—we analyze molecular responses to the variation in the nano-chemical environment by examining their fingerprinting vibrational modes at the sub-molecular scale. By precisely tuning the junction geometry, material, and the interaction between the molecule and other surface entities, we can selectively influence specific bonds, paving the way for bond-selective control in chemistry.
