Tim Berk
Mechanical and Aerospace Engineering
Assistant Professor
Biography
Dr. Tim Berk has been an assistant professor in the Department of Mechanical and Aerospace Engineering at Utah State University (USU) since Spring 2022. Prior to this appointment, Tim spent time as a Postdoctoral researcher at the University of Minnesota and at Johns Hopkins University. Tim obtained his PhD from the University of Southampton (UK, 2018) and a BS and dual MS from the University of Twente (Netherlands).
Research Interests
Tim's research revolves around experiments in fluid dynamics. Particularly, he focusses on multiphase turbulence, which he studies using state-of-the-art optical measurement techniques. Problems of interest include the effect of turbulence on transport of sand and dust in the atmospheric boundary layer, on the settling of snowflakes in atmospheric turbulence and on the injection of fuel in a combustion engine. These and other environmental and industrial processes are studied using experimental setups over a range of sizes, from small-scale bench-top experiments to full-scale field studies. This combination helps dissect the fundamental physical mechanisms driving real-world flows.
