Students and Postdocs

Iremnur Ceylan, a graduate research assistant at the University of Massachusetts Amherst under the supervision of Assoc. Prof. Jae-Hwang Lee, is actively engaged in pioneering research concerning the high-strain rate deformation of materials. Her scholarly pursuits are centered on elucidating the mechanical performance of complex systems across a diverse range of extreme conditions, with the aim of gaining a fundamental understanding of far-from-equilibrium phenomena. Ceylan employs the Laser-Induced Projectile Impact Test—a cutting-edge micro-ballistic methodology in materials science and mechanics. Her methodology provides high-strain-rate mechanical stimuli accompanied by precise kinetic information, thus shedding light on multiscale mechanical and microstructural phenomena. As a part of CAMCSE, Ceylan is contributing to the profound understanding of complex materials and their mechanical responses under extreme conditions.
