Five University of Washington faculty members have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 17, are Maria “Masha” Baryakhtar, an assistant professor of physics, Matthew R. Golder, an assistant professor of chemistry, and Willem Laursen, an assistant professor of biology, all in the College of Arts & Sciences; Vikram Iyer, an assistant professor of computer science in the College of Engineering; and Frankie Pavia, an assistant professor of oceanography in the College of the Environment.
Since the first Sloan Research Fellowships were awarded in 1955, and including this year’s fellows, 136 faculty from University of Washington have received a Sloan Research Fellowship, according to the Sloan Foundation.
Sloan Fellowships are open to scholars in seven scientific and technical fields — chemistry, computer science, Earth system science, economics, mathematics, neuroscience and physics — and honor early-career researchers whose achievements mark them among the next generation of scientific leaders.
The 126 Sloan Fellows for 2026 were selected by researchers and faculty in the scientific community. Candidates are nominated by their peers, and fellows are selected by independent panels of senior scholars based on each candidate’s research accomplishments, creativity and potential to become a leader in their field. Each fellow will receive $75,000 to apply toward research endeavors.
This year’s fellows come from 44 institutions across the United States and Canada.
Maria “Masha” Baryakhtar
Baryakhtar’s research in the Department of Physics focuses on theories beyond the established Standard Model of particle physics and on creating new ideas and directions for testing these theories. Such theories address outstanding puzzles in our existing understanding and often predict new, ultralight, feebly interacting particles beyond those we have discovered so far. The existence of these particles can be tested through exquisitely precise experiments in the lab or by observing extreme objects in the sky like black holes and neutron stars.
“My research program aims to search high and low for new, as yet hidden particles and forces. Because of their nature, these particles require a range of creative search strategies. The directions I am establishing use new technologies and data from the sky to the lab and may be the only way to shed light on the truly dark elements of our universe.”
Matthew R. Golder
Golder’s research in the Department of Chemistry addresses the omnipresent “plastics problems” from two different vantage points. First, the team thinks about new ways to prolong the useful lifetime of commodity materials. The researchers use molecular engineering to keep plastics in use longer before discarding. The Golder Research Group also develops new methods to make and repurpose plastics, with an emphasis on green chemistry and making plastics more recyclable.
“Plastics are paramount to daily life, so there are numerous opportunities to improve performance and mitigate waste. We operate at the interface of fundamental organic chemistry and applied materials science to enhance plastic integrity and sustainability. By doing so, my students really take this mission to heart and constantly dream up new ways to creatively (re)design commodity plastic materials.”
Vikram Iyer
Iyer’s research in the Paul G. Allen School of Computer Science & Engineering seeks to address sustainability challenges across the full computing stack from creating recyclable polymers to reimagining the way we build computing hardware by designing AI systems to estimate carbon footprint and optimize the design of future low-carbon devices. In particular, the group’s work goes beyond simply reducing energy consumption to quantify and tackle the environmental impacts of materials and manufacturing.
“My group both leverages innovations from outside of computing like chemistry and material science to drive sustainability and applies computing techniques from AI to programming languages to fundamentally advance environmental sciences. This work is highly interdisciplinary and takes some extra effort at the beginning for each of us to understand the technologies and methods developed by our collaborators. By doing this, we can come up with completely new ideas that have real world impact like enabling carbon reduction at major companies like Amazon, and creating systems like battery-free robots that push the boundaries of technology.”
Willem Laursen
Laursen’s research in the Department of Biology is focused on understanding how animals detect and respond to sensory cues in their environment. Using genetic manipulation, neurophysiology and behavioral analyses, the lab’s current focus is to understand how disease vector mosquitoes use sensory cues to locate hosts, mates and egg-laying sites.
“It is an honor to be selected as a Sloan Fellow. This award will support our lab’s research on the role of the mosquito gustatory, or taste, system in critical behaviors, such as blood feeding. While mosquitoes use all of their senses to efficiently locate hosts, their taste system is surprisingly understudied. By examining the gustatory systems of blood-feeding insects, we hope to better understand how taste cues on the skin and in the blood are detected and used to guide their specialized behaviors, lines of inquiry that could ultimately identify new targets for controlling the spread of disease.”
Frankie Pavia
Pavia’s research in the School of Oceanography develops and applies new isotopic techniques to study feedbacks in the Earth system. His work spans the oceanic, atmospheric, lithospheric, and human domains, on timescales ranging from minutes to millennia.
“The oceans are a repository and reactor for materials originating on land, in the atmosphere, in Earth’s interior and from outer space. Chemical fingerprints of oceanic interactions with these reservoirs can be unlocked using unique analytical chemistry techniques, especially those involving the precise measurement of isotope ratios. My current research aims to discover new interactions between the oceans and the Earth system in the past, present and future, by pioneering interdisciplinary studies that use measurements of stable and radioactive isotopes to determine how much and how fast the Earth system changes. Current projects involve using cosmic dust to reconstruct sea-ice coverage, sensitively detecting human-derived carbon in the oceans, and understanding the past and future impacts of oceanic calcium carbonate dissolution on storage of atmospheric carbon dioxide.”
