Hello! I'm Lehman, a software engineer at the Flatiron Institute's Scientific Computing Core. Before that, I received my Ph.D. under Daniel Eisenstein at the Center for Astrophysics | Harvard & Smithsonian. My main research projects were on high-performance cosmological $N$-body simulations and the formation and statistics of large-scale structure. My general research interests include cosmology and high-performance computing.
During my Ph.D. and postdoc, I was the lead developer of the Abacus cosmological $N$-body code, which I worked on with Daniel Eisenstein and Nina Maksimova. I continue to support that project and some smaller ones, like Corrfunc, which I develop with Manodeep Sinha.
