Lorenz T. (Larry) Biegler is the Bayer Professor of Chemical Engineering at Carnegie Mellon University. He joined the faculty at CMU after receiving his PhD from the University of Wisconsin in 1981. Prof. Biegler was appointed as the Bayer Professor in 1996. His research is computer aided process engineering (CAPE) including flowsheet optimization, optimization of systems of differential and algebraic equations, reactor network synthesis and algorithms for constrained, nonlinear process control. Prof. Biegler has been a visiting scholar at Northwestern University, a scientist-in-residence at Argonne National Lab, a Distinguished Faculty Visitor at the University of Alberta, a Gambrinus Fellow at the University of Dortmund, a Fulbright Fellow at the University of Heidelberg and a Distinguished Jubilee Lecturer at IIT Bombay. He has authored or co-authored over 250 archival publications, authored or edited nine books and given numerous invited presentations at national and international conferences.The textbook “Systematic Methods of Chemical Process Design,” co-authored with Ignacio Grossmann and Art Westerberg, is a landmark in process systems engineering education. Larry’s latest book “Nonlinear Programming: Concepts, Algorithms and Applications to Chemical Processes.” issued in 2010.
