Assistant Professor
PhD (2010), University of Michigan, Ann Arbor

Research Interests: Composite materials, especially woven composite materials; ballistic, blast and other high rates of loading with experimental validation; and finite element modeling of composite systems including rate-dependent properties.

Pankow earned his BS in mechanical engineering from California Polytechnic State University in 2005. In 2007 he received an MSE in mechanical engineering from the University of Michigan, where he continued his education and received his PhD in 2010. After graduating, Pankow started his position as a postdoctoral researcher at the US Army Research Laboratory in Aberdeen, Md.

Pankow’s research looks at understanding composite materials under high rates of loading. Many of the applications for composite materials are in extreme environments in which ballistic, blast and high-speed impact will be the main design consideration. Understanding how these materials respond in these environments will help his research group better design for numerous applications, taking full advantage of weight savings. Using controlled tests, the group can understand how these materials behave through high-speed diagnostics and in-situ full field measurements. These observations can then be validated through means of theory or detailed finite element modeling to verify the results.
