__

Amir H. Hirsa received his B.S. degree in aeronautics from San Jose State University in 1983, and M.S.E. and Ph.D. degrees in aerospace engineering from University of Michigan in 1986 and 1990, respectively. He joined the RPI faculty in 1990.

Research Interests and Activities: Fluid mechanics and interfacial phenomena. Current research interests are in the area of interfacial hydrodynamics, including monolayer hydrodynamics (such as measurements and modeling of intrinsic interfacial viscosities for lung surfactant applications), and other surface tension effects such as capillarity (e.g. capillary instability and its applications to liquid lenses). Our work in the area of bio-fluids also includes studies of protein structure in the presence of flow, especially at the air/water interface. We have made advances to experimental techniques including particle image velocimetry, nonlinear optical technique of second-harmonic generation, as well as Brewster angle microscopy for flowing systems. We also work in the area of microfluidics, especially in relation to free surface effects. Our research has received funding from the Office of Naval Research (ONR), Defense Advanced Research Projects Agency (DARPA), National Science Foundation (NSF), and National Aeronautics and Space Administration (NASA).
