I'm affiliate graduate faculty at the University of Hawai'i at Mānoa, welcome to my webpage! My broad research interest is Einstein's theory of gravitation, General Relativity (GR). I am currently exploring the observational consequences of cosmological energy shifts within relativistic compact objects (e.g. stellar collapse remnants such as non-singular black holes and neutron stars). I frequently collaborate with Profs. Nishimura and Farrah within the Department, and Prof. Weiner within the Department of Mathematics. Feel free to contact me if you would like to know more about our team! My thesis work focused on cosmological applications of GR, in particular, the Dark Energy problem. My past work has focused on the use of numerical simulations to compare and constrain proposed extensions of GR through existing astrophysical data. I believe observation is paramount.
