C. Cem Tasan

Research

Professor Tasan explores the boundaries of physical metallurgy, solid mechanics, and in-situ microscopy, in order to design new alloys with exceptional damage-resistance. 

He received  his Ph.D. in Mechanics of Materials from Eindhoven University of Technology in the Netherlands. Following postdoctoral work at Max-Planck-Institut für Eisenforschung in Germany, he was appointed as a Group Leader there, leading the Adaptive Structural Materials group until joining MIT in 2016.

His group at MIT mainly focuses on (i) developing new in-situ characterization tools and methods, (ii) improving the physical understanding of transformation, deformation, damage micro-mechanisms in metallic materials; (iii) designing damage-resistant microstructures and alloys.
