Professional Background
Dr. Ralph Budwig is Professor and past Chair of the Mechanical Engineering Department at University of Idaho. Since August 2007 he is a faculty member at the Center for Ecohydraulics Research (CER) in Boise and the Director of the Center for Ecohydraulics Research Stream Laboratory. His areas of specialization include experimental and theoretical fluid dynamics, turbulence, and experimental methods. Dr. Budwig's research areas have included cardiovascular fluid dynamics, advanced ultrasonic manipulation and fractionation of particles, laboratory pedagogy, and novel techniques for dynamic measurements of velocity, temperature, and species concentration fields in flowing fluids.
