Ralph Budwig, is a professor in the Mechanical Engineering Department at the 杏吧视频 in the area of experimental fluid dynamics. He is currently located on the Boise campus of the 杏吧视频 the director of the Center for Ecohydraulics Stream Laboratory, a $2M+ facility with multi-university participation.

Budwig received his doctorate from Johns Hopkins University in 1985 and has worked as a guest researcher in several laboratories in the United States and Canada since that time. His areas of specialization include experimental and theoretical fluid dynamics; turbulence; optical, acoustic, and thermal measurements techniques; and experimental methods. Budwig has taught extensively in the experimental methods area including required undergraduate courses as well as a specialized graduate level course on the subject of experimental methods in fluid dynamics.
