Raymond R. Tucker Distinguished I-CARES Career Development Assistant Professor
Biography

Professor Williams joined the faculty at Washington University in St. Louis in fall 2010. Previously, he served as a post-doctoral associate at the University of Minnesota Particle Technology Laboratory and as a post-doctoral scientist at Aerodyne Research, Inc.

As a PhD student at the University of California-Berkeley, he developed novel organic aerosol measurement instrumentation, and deployed and operated this instrumentation in multiple large-scale international and domestic field campaigns to determine the sources and transformation processes of atmospheric particles.

In 2011, Professor Williams was named the Raymond R. Tucker Distinguished ICARES Career Development Assistant Professor for his work on atmospheric aerosol chemistry. He currently serves as the American Association for Aerosol Research (AAAR) Chair of the Aerosol Chemistry working group and Vice-Chair of the Instrumentation working group.

Research
Professor Williams’ research interests focus on the exploration of the composition, chemistry and physical properties of Earth’s atmosphere to determine the role of biogenic and anthropogenic gases and particles in Earth’s climate system. Current projects include the study of particle formation from biomass combustion, secondary particle formation from photochemical aging, and novel instrumentation development.
