Kevin Hemker is the Alonzo G. Decker Chair and Professor of Mechanical Engineering at Johns Hopkins University and holds joint appointments in the Departments of Materials Science & Engineering and Earth & Planetary Sciences. He joined the faculty at Johns Hopkins University in 1993, served as Chair of the Department of Mechanical Engineering (2007-2013), as editor of Scripta Materialia (2004-2011), member of the DARPA Defense Science Research Council (2010-2014), a member of the SRI Technology Council (2017-2019) and was the 2018 President of The Minerals, Metals, Materials Society (TMS). He is currently a member of the HRL Technical Advisory Group and the NCMS AMMP Advisory Council. Hemker has been named Fellow of AAAS, ASME, ASM International and TMS.
Hemker has mentored over 75 postdoctoral fellows, doctoral and masters students since coming to Hopkins, about 20 of whom now have tenured or tenure-track academic positions in major research universities. His group strives to elucidate the underlying atomic-level details that govern the mechanical response, performance and reliability of disparate material systems. They have made key observations and discoveries that have challenged the way the community thinks about and understands materials behavior in: nanocrystalline materials, materials for MEMS, metallic micro-lattices, thermal barrier coatings for satellites and gas turbines, armor ceramics, and high temperature structural materials in general.
