News from Natural Sciences

CHEMISTRY AND BIOCHEMISTRY - UO lab spaces are some of the most resource-intensive areas on campus, using two to three times more energy than typical offices and generating unique kinds of waste that aren’t collected through regular recycling streams. The recently launched Sustainable Labs program offers researchers a flexible framework to foster more sustainability in labs.
EARTH SCIENCES - CRESCENT wrapped up its first-ever cohort for the Geoscience Education and Inclusion (GEI) Twinning Program. Over the course of a year, students worked with mentors on fully funded research projects, developing practical skills and presenting their findings to fellow scientists. The program manager, Shannon Fasola, said it offered a unique opportunity because students could focus on research without having to worry about finances. The program included Libby Tonn, a CAS student.
During the summer, 25 faculty members from the college’s Division of Natural Sciences took part in the Mobile Summer Institute for Scientific Teaching. The weeklong workshop offered faculty members ways to transform traditional lectures to be more inclusive and hands on that puts students at the center of learning. It brought together instructors not only from disciplines such as biology, chemistry, and physics—and across the campus.

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

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. 

 

 

The new School of Computer and Data Sciences will be open in fall 2023 to students throughout the UO, with the goal of serving 2,000 undergraduate majors and students in existing and new undergraduate and graduate programs.

School of Computer and Data Sciences

The mission at SCDS is to empower a diverse population of students and faculty working to advance knowledge in computer and data science, train the next generation of scholars, and engage with the wider world to tackle interdisciplinary challenges.

To do this, we start by applying our knowledge and experience at home across the University of Oregon campus.

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.

“Trapped Ion Mobility-Assisted Sequencing and Analysis of Protein Ions”

The sequencing of intact proteins within a mass spectrometer enables the profiling of post-translational modification (PTM) crosstalk but is frequently hindered by convoluted spectra and the fact that tandem mass spectrometry (MS/MS) techniques often generate poor sequence coverages when applied to protein ions. Ion mobility spectrometry is a promising tool to overcome the complexity of these spectra by separating ions by their mass- and size-to-charge ratios. Here, we discuss the development of an activation method that when paired with trapped ion mobility spectrometry deconvolutes MS/MS spectra and improves the sequence information provided by intact protein focused workflows. Furthermore, we demonstrate the isolation and fragmentation of mobility separated product ions with the downstream quadrupole and collisional cell. This second activation step improves sequence coverage because many of the labile bonds have been depleted during the first dissociation and subsequent dissociation events are more evenly distributed throughout the product ion backbone. When these two activation steps are combined this technique generates 92% of the sequence coverage of the most effective MS/MS technique, but it accomplishes this feat in a fifth of the time and can be facilely integrated with liquid chromatographic separations. Lastly, we demonstrate that this activation technique can be utilized to elucidate the conformation of protein ions.
