Arup K. Chakraborty Arup K. Chakraborty obtained his PhD in chemical engineering at the University of Delaware. After postdoctoral studies at the University of Minnesota, he joined the faculty at the University of California at Berkeley in December 1988. He rose through the ranks, and ultimately served as the Warren and Katherine Schlinger Distinguished Professor and Chair of Chemical Engineering, Professor of Chemistry, and Professor of Biophysics at Berkeley. He was also Head of Theoretical and Computational Biology at Lawrence Berkeley National Laboratory. In September of 2005, Arup moved to MIT where he is the Robert T. Haslam Professor of Chemical Engineering, Chemistry, and Biological Engineering. The central theme of his research today is the development and application of statistical mechanical approaches to study how T lymphocytes, orchestrators of the adaptive immune response, function. Arup’s work has been recognized by many honors that include the Allan P. Colburn and Professional Progress awards of the American Institute of Chemical Engineers, a Camille Dreyfus Teacher-Scholar award, a Miller Research Professorship, a National Young Investigator award, a NIH Director’s Pioneer Award, and the E.O. Lawrence Memorial Award for Life Sciences. Arup is a member of the National Academy of Engineering and a Fellow of the American Academy of Arts & Sciences. He has delivered over 180 invited lectures that include many named lectures.
