Experimental and computational fluid mechanics and fluid-structure interactions; flow and elasticity in nature; biomechanics of human and animal voice production.
Dr. Thomson joined the BYU faculty in 2004. He received bachelor’s and master’s degrees in mechanical engineering from BYU (‘99, ‘00) and a PhD in mechanical engineering from Purdue University (‘04). From 2014 to 2016 he taught mechanical engineering at BYU-Idaho. He and his wife and their six children lived in Erlangen, Germany from 2011 to 2012 while he was a visiting faculty member at the Friedrich-Alexander University Erlangen-Nürnberg. He was also a visiting faculty researcher at Wright Patterson Air Force Base during the summer of 2008.
Dr. Thomson and his students are currently primarily focused on researching the biomechanics of human voice production. More broadly, he is interested in studying systems in nature in which fluid motion and structural elasticity are coupled. He is, or has been, a principal or co-investigator on over $7 million in external research grants, primarily from the National Institute on Deafness and Other Communication Disorders (NIDCD, a component of the National Institutes of Health, NIH), as well as from the National Science Foundation (NSF) and the Air Force Office of Scientific Research (AFOSR).
He teaches undergraduate and graduate courses in engineering measurement systems, computational fluid dynamics, and experimental fluids. He is a past Associate Editor for the Journal of Speech, Language, and Hearing Research (JSLHR) and currently serves on the International Advisory Board of the Advances in Quantitative Laryngology conference series. He is a past recipient of the NSF Graduate Research Fellowship and the ASME Graduate Teaching Fellowship.
Dr. Thomson was born and raised in Idaho, served a mission for The Church of Jesus Christ of Latter-day Saints in New Zealand from 1992 to 1994, and is semi-conversant in Tongan. He enjoys spending time with his family, traveling, and distance running.
