Michael A. Troxel

Michael A. Troxel is an Associate Professor of Physics at Duke University's Department of Physics within Trinity College of Arts & Sciences. He earned his Ph.D. and M.S. from the University of Texas, Dallas, and dual B.A./B.S. in Physics from the University of Oklahoma. His research focuses on cosmology, dark matter, and galaxy evolution through advanced surveys like the Dark Energy Survey (DES) and the Nancy Grace Roman Space Telescope missions.

• Ph.D., University of Texas, Dallas (2014)
• M.S., University of Texas, Dallas (2011)
• B.A./B.S., University of Oklahoma (2008)

Troxel's work leverages weak gravitational lensing, galaxy clustering, and multiwavelength observations to map cosmic structure and constrain dark energy models. His recent studies simulate next-generation telescopes' capabilities for redshift measurement and cosmic shear analysis, aiming to resolve non-linear matter suppression from baryonic feedback. He contributes to major collaborations like DES, SPT, and ACT, integrating machine learning for galaxy classification and cosmological inference.

His publications highlight trends in cosmic structure mapping, Roman Space Telescope simulations, and baryonic feedback modeling. Awards include the Department of Energy's Early Career Award (2020). Troxel leads grants from Jet Propulsion Lab and DOE for cosmological software development (2020-2027) and Roman Survey optimization (2024-2026). He co-chairs the DES Science Committee and serves as Associate Chair of Duke's Physics Department (2025-present).
