Professor Kumar's research interests include experimental characterization and analysis of defects, deformation and fracture in structural metals and alloys, and intermetallic and metal-matrix composites. Current research activities focus primarily on various intermetallics, novel high-strength, high-toughness steels, nanocrystalline metals and alloys, and refractory alloys for aerospace and defense applications. He also collaborates extensively with scientists from Oak Ridge National Laboratories.
Prior to joining Brown in January 1995, Professor Kumar was a senior staff scientist at Martin Marietta Laboratories in Baltimore, MD. While there, he co-invented a new generation of aluminum-copper-lithium alloys for aerospace cryogenic fuel tank applications. The fuel tank for the Space Shuttle launched on June 2, 1998 was built out of this family of alloys. He received the Outstanding Technical Paper Award at the First and Third International Symposia on Structural Intermetallics in 1993 and 2002, the Maryland Distinguished Young Scientist Award in 1994, participated as a member of National Academies Committee for "Alternative Technologies to Anti-Personnel Landmines" from 1999 to 2001 and was made a Fellow of ASM International in 2003.
