Joshua B. Bostwick joined the department in January 2016. His research addresses fundamental problems on interfacial flows with an emphasis on wetting and the interactions of liquids with soft substrates (elastocapillarity). More broadly, he is interested in pattern formation on interfaces, surface tension-driven phenomena, complex fluids, and soft matter. He is attracted to such problems because it is often possible to elucidate the underlying physics using simple, yet rigorous, mathematical models to compare to experiments. He is a recipient of the NSF CAREER Award and currently serves as an Associate Editor of the Journal of Engineering Mathematics.
