UCI School of Physical Sciences Driving foundational and transformational discoveries in mathematics and the physical sciences.

One of the founding academic units established in 1965, the UCI School of Physical Sciences has built an international reputation of distinction in scientific research while also embracing the teaching mission of a public university. The School's world-renowned faculty members and research scientists teach and perform research with students to explore the ever-advancing frontiers of knowledge. From peering back at the first instants in time of the big bang to predicting the future of our planet, from imaging individual atoms and molecules to modeling living cells and cancer tumors, and from synthesizing new molecules to understanding the evolution of the universe – scientists and mathematicians explore all time scales and all size ranges to learn nature's secrets and provide the foundation for the tools used by a modern technological society. The School is comprised of four highly ranked departments: Chemistry, Mathematics, Earth System Science, and Physics & Astronomy. Currently, the School has 159 faculty members, 2,100 undergraduate students, and 500 graduate students. In 1995, the School garnered international prominence when founding faculty members F. Sherwood Rowland (chemistry) and Frederick Reines (physics) each received the Nobel Prize, making UCI the first public university with faculty receiving the award in two different fields in the same year. Building on this foundation, 11 faculty members have been elected to the National Academy of Sciences, and 9 have been elected to the American Academy of Arts and Sciences. Consistently, professors and students are singled out for prestigious awards recognizing their scientific excellence. The school also takes great pride in the rankings by the National Research Council (NRC) that place each of the four departments above the 90th percentile.

Ava McIlvaine had to get to Greenland.

McIlvaine, who’s a Ph.D. candidate in the lab of Professor Brett Walker and Ellen Druffel in the UC Irvine Department of Earth System Science, studies the role organic matter dissolved in seawater plays in the global carbon cycle, with a focus on how marine microbes influence the flow of organic carbon.

This summer, McIlvaine boarded a research ship — the RRS James Cook — and sailed from Canada to Greenland so she could retrieve crucial samples from the Labrador Sea. The ship was almost at her sampling sites — she could even see Greenland — but then the ship turned around and headed back toward Canada.

McIlvaine’s heart dropped. Find out what happened next by diving into McIlvaine’s field notes from her expedition.

A Moment of Science

What if the secret to designing more energy-efficient technologies is right beneath our noses? Or, rather, right behind our noses? The lab of Professor Zuzanna Siwy in the UC Irvine Department of Physics & Astronomy draws inspiration from the way the human brain operates in order to design chips that require far less energy than chips in conventional technologies. The work helps address a burgeoning need for energy-efficient tech. 

In the photo, one of Siwy’s graduate students, Matt Schiel, holds up an experimental chip that uses fluids to help keep it cool. “The neurons in our brain use nanoscale pores to efficiently transmit information and make computations every second,” said Schiel, who alongside Siwy published a recent paper in ACS Nano describing their research. “We’re working on making synthetic nanopores that respond to external signals in a similar way to turn on and off the flow of ions in water while using less energy to do this switching.”

Press release: UC Irvine astronomers discover exoplanet that may harbor life. The planet is twice the size of Earth, and at only 25 light years away from Earth, it’s our cosmic next-door neighbor. Find out how much we know – and still don’t know – about the planet, and what it all means for future planet-hunting telescopes.

This week, the UC Irvine Department of Physics & Astronomy is hosting Neutrino 2026 — an international scientific conference featuring the latest research into the neutrino, which is a subatomic particle that was co-discovered by Nobel laureate and the founding dean of the UC Irvine School of Physical Sciences, Frederick Reines. The conference has 639 attendees representing 33 countries across six continents.

“Neutrino 2026 has been an extraordinary week, showcasing exciting new discoveries and increasingly precise measurements that are deepening our understanding of neutrino properties and their role in the universe,” said Mu-Chun Chen, UC Irvine professor of physics and one of the organizers of the conference.

With heavy hearts, we share that our trusted colleague and friend of more than 25 years, Francois William Primeau, passed away on Friday. This is an unimaginable loss for all who knew him. He is survived by his wife, Juno, and their son, Louis. We were all fortunate to know him and to count him among our community.

Our trusted colleague and friend of more than 25 years, Francois William Primeau, passed away on Friday.

Ph.D. student Isaac Standen of the UC Irvine Department of Earth System Science uses a sonic anemometer to measure the uptake of atmospheric hydrogen gas into soils outside Croul Hall, which houses UCI ESS. The work is part of a bigger effort to reduce uncertainties in the role soils play in the hydrogen cycle. In addition to Standen, the work is spearheaded by UCI’s Professor Eric Saltzman, his postdoctoral researcher John Patterson, and Cyril Mccormick.
