BIOGRAPHY

Morteza Mehrabadi received his B.S. degree in Mechanical Engineering (1969) from Tehran University, and his M.S. (1973) and Ph.D. (1979) degrees in Mechanical Engineering from Tulane University. He returned to Tulane as an Assistant Professor of Mechanical Engineering in 1982 after a postdoctoral fellowship at Northwestern University in Evanston, Illinois. He was promoted to the rank of Associate Professor in 1985 and Professor in 1992. He served as the department Chair from October 1998 until June 2007 when he became Professor and Chair of Mechanical Engineering at San Diego State University. He has been a Visiting Faculty at the Laboratoire de Mecanique des Solides, Ecole Polytechnique, Palaiseau, France; at Tohoku University, Sendai, Japan; and at the Naval Research Laboratory in Washington, D.C. The special interests of Dr. Mehrabadi include: materials behavior, in particular, micromechanical aspects of deformation and failure of materials; modeling of mechanical behavior of granular materials, tissue mechanics, modeling of the initial rearrangement stage of particles in liquid phase sintering, conservation laws and constitutive equations of density-gradient-dependent fluids, and kinematics of continua. Dr. Mehrabadi's research has been supported by NSF, NRL, DOE, and private industry. He has also received several fellowships from national laboratories. Dr. Mehrabadi has reported results of his research at national and international professional meetings, and has organized symposia and chaired technical sessions for professional societies. He currently serves on the editorial boards of Mechanics of Materials and International Journal of Plasticity. He is an ASME Fellow and serves on the joint Applied Mechanics-Materials Divisions Committee on Constitutive Equations and the Committee on Geomechanics. He is also a member of Tau Beta Pi, Pi Tau Sigma, Society of Engineering Science (SES), American Society of Engineering Education (ASEE), and American Academy of Mechanics (AAM). He is the recipient of several teaching awards including the Society of Tulane Engineers and Lee H. Johnson Award for Teaching Excellence.
