Professor Jae-Hwang Lee is an Associate Professor in the Department of Mechanical and Industrial Engineering at the University of Massachusetts Amherst, where he has been a faculty member since 2014. He received his Ph.D. in Condensed Matter Physics from Iowa State University in 2006, with a focus on 3D photonic metamaterials and their applications in energy systems. As a postdoctoral researcher at the Institute for Soldier Nanotechnologies at MIT, he developed the laser-induced projectile impact test (LIPIT) technique for investigating the extreme mechanical behavior of micro- and nanoscale materials. Prior to joining UMass Amherst, he served as a Research Scientist at the Richard Smalley Institute for Nanoscale Science and Technology at Rice University. His current research explores the extreme materials science and mechanics of mechanical metamaterials, soft matter, and compositionally complex metals.
