Current Roles

Senior Data Scientist -- ConcertAI (2022–)

Member Board of Advisors -- Center for Gravitational Waves and Cosmology, WVU (2021–)

Previous Experience

Senior Research Scientist -- GNS Healthcare (2018–2022)

At GNS, I worked in R&D where I developed cutting-edge machine learning algorithms to model sparse, longitudinal healthcare data. I had a somewhat unique position in the company as the primary creator of the Zeus causal inference platform, which was entirely seperate from GNS's flagship product REFS.

Postdoctoral Research Associate -- Department of Mathematics, WVU (2015–2018)

As a Postdoctoral Research Associate at West Virginia University (2015–18), I developed custom open source computer code to simulate and study gravitational phenomena which became 180 times more efficient than our competitors. This work has been presented at 5 conferences, lead to 2 publications in Physical Review D, and the creation of an Open Source Project named SENR/NRPy+. My primary research focus involves generating accurate numerical simulations of the inspiral and merger phases of orbiting black hole binaries. In particular, I am interested in exploring the extreme limits of general relativity in the regime of near maximal intrinsic angular momentum. In addition to probing the peculiarities of nonlinear gravity theory, I generate astrophysical gravitational waveforms for use in gravitational wave detection experiments.
