About Me

I started my education in 2000 in the honors college at the New Jersey Institute of Technology. I received both B.S. and M.S. degrees at NJIT from the mechanical engineering department, finishing with an M.S. in 2006. My research while at NJIT was in the area of computational granular science. In 2006 I went on to the solid mechanics and materials laboratory at the Massachusetts Institute of Technology. I received my Ph.D. in mechanical engineering in 2011, specializing in solid mechanics. After MIT, I became a postdoctoral researcher in the engineering division at Lawrence Livermore National Laboratory in California. My research focus in the past few years has been the development of experimentally validated continuum level constitutive theories for large-deformation multi-physics behavior of materials, and the associated numerical implementation. My work spans most aspects of mechanics; experimental characterization, theoretical modeling, numerical implementation, and experimental validation.
