Biography:
Since 1990, James D. Lee has taught in two areas of mechanical engineering (solid mechanics, control) at the Department of MAE. He has also been an active researcher in those areas. He is a registered Professional Engineer in Washington, DC and a member of ASME, Sigma Xi, American Academy of Mechanics, and New York Academy of Science. He has been teaching and/or doing research in universities (Purdue U., West Virginia U., U. of Akron, U. of Minnesota and GWU), industry (The General Tire and Rubber Company), and US government laboratories (NIST and NASA). His research fields include liquid crystals, fracture mechanics, composite materials, numerical analyses, control, robotics, metal forming process, finite element methods, meshless methods and microcontinuum physics. Most recently, he has been doing research on multiphysics micromorphic theory to bridge the gap between atomistic model and continuum field theory. He has been a principal investigator of research grants awarded by
NASA and NSF. He has directed eight doctoral
dissertations and many master theses. He has published more than 100
technical papers including 60 referred journal articles.
