Education

• Ph.D., Massachusetts Institute of Technology, 2001 
• M.S., Harvard University, 1998 
• B.S., The Cooper Union, 1996

Research Interests: 

Professor Rothstein's research interests are quite broad, drawing from topics commonly associated with mechanical engineering, but also from fields related to chemical engineering, biomechanical engineering and optical engineering. His current research program is a well balanced experimental and theoretical research program in the dynamics of complex fluids. Among other topics, Professor Rothstein research interests include non-Newtonian fluid dynamics, non-isothermal flow, hydrodynamics stability, optical measurement techniques, microfluidics, laminar and turbulent drag redution, rheology and polymer processing.
