Shamberger is an associate professor in the Materials Science and Engineering Department at Texas A&M University. Prior to this, he served as a materials research engineer for the Air Force Research Lab in the Nanoelectronic Materials Branch.

Research

Shamberger’s research focuses on reversible phase transformations, including understanding the role and implications of irreversible thermodynamics in energy dissipation in near equilibrium phase transformations. He lead’s inverse design efforts to map the electrical response of non-trivial ensembles of neuromorphic elements to intrinsic material and molecular properties. He experimentally investigates the role of site-selective modification in modulating intercalation phenomena, affecting energy landscapes, and altering transformation mechanisms.
