Aaron Thomas Professor, Director of Native American Research Laboratory

Office: Chemistry, 201


Dr. Aaron Thomas is currently the Director of Indigenous Research and STEM Education (IRSE) at the University of Montana, in addition to his role as Associate Professor of Chemistry and Biochemistry.

Prior to arriving at the University of Montana in January 2013, Aaron served the University of Idaho as Assistant and Associate Professor of Chemical Engineering, and Director of the Idaho Space Grant Consortium and Idaho NASA EPSCoR Programs.

A member of the Navajo Nation, Aaron earned a BS in Chemical Engineering from Stanford University (1996) and a Ph.D. in Chemical Engineering from the University of Florida (2001). Dr. Thomas' research topics include Microfluidics and novel separation processes for gases and biological materials. He is a recipient of the prestigious National Science Foundation CAREER and PbioECASE Award given to young faculty in science and engineering.

Dr. Thomas is committed to increasing the number of Native American and Alaska Native students with advanced degrees in STEM fields. Accordingly, he has constructed a comprehensive service plan that (in the earliest years) promotes exciting STEM education activities in Montana's reservation middle schools and (later) supports their undergraduate and graduate STEM studies at the University of Montana.
