PRINCIPAL INVESTIGATOR


Corey S. O'Hern

Corey is an Associate Professor with Tenure in the Departments of Mechanical Engineering & Materials Science, Applied Physics, and Physics and Graduate Program in Computational Biology & Bioinformatics at Yale. Before joining the faculty at Yale, he was a postdoctoral fellow working with Prof. Andrea Liu (UPenn, Physics) who was then at UCLA and Prof. Sidney Nagel (UChicago, Physics) on computational studies of jamming transitions in frictionless granular materials and glass transitions in model glass-forming liquids. Corey recieved his Ph.D. in Physics from the University of Pennsylvania in 1999; his dissertation focused on developing elasticity theories for liquid crystalline systems with biological importance such as DNA-cationic lipid complexes. See his Ph.D. thesis. Corey was an undergraduate at Duke University and graduated in 1994 with a B.S. in Physics. He likes to point out that while at Duke, he performed experimental research on granular materials in Bob Behringer's Lab and to his knowlege did not break anything! His CV is available here.
