Professor Nick Sahinidis received his Diploma in Chemical Engineering from the Aristotle University of Thessaloniki, Greece in 1986 and his Ph.D. in Chemical Engineering from Carnegie Mellon University, Pittsburgh, Pennsylvania in 1990.

Between 1991 and 2007, he served on the faculty of the University of Illinois at Urbana, initially as an Assistant Professor and Associate Professor of Mechanical and Industrial Engineering and later as an Associate Professor and Professor of Chemical and Biomolecular Engineering. In 2007, he moved to Carnegie Mellon University, where he is now John E. Swearingen Professor of Chemical Engineering.

He has served on the editorial boards of many journals, including Industrial & Engineering Chemistry Research, Journal of Global Optimization, Mathematical Programming Computation, Optimization and Engineering, Optimization Letters, and Optimization Methods and Software. He has also served in numerous positions within INFORMS (Institute for Operations Research and the Management Sciences) and AIChE (American Institute of Chemical Engineers). He is currently the programming chair of the CAST division of AIChE.

His doctoral advisees have become members of the faculty at major research universities, including Georgia Institute of Technology and Purdue University, and leading industrial laboratories, including those of American Airlines, BPAmoco, and ExxonMobil.


Ph.D., 1990, Carnegie Mellon
Diploma, 1986, Aristotle University of Thessaloniki, Greece


Sahinidis' research concerns optimization of carbon capture models, surrogate models for energy systems, synthesis of solid sorbent carbon capture process and storage of CO2 in geological formations and global optimization of convex nonlinear optimization problems.
