Lawrence Widrow

Lawrence Widrow is a Professor in the Department of Physics, Engineering Physics & Astronomy at Queen's University, where he leads research in theoretical astrophysics and cosmology. He earned his PhD from the University of Chicago under Michael Turner and held postdoctoral positions at Harvard-Smithsonian Center for Astrophysics and Canadian Institute for Theoretical Astrophysics.

Research focuses on galactic dynamics, dark matter, and cosmic structure formation. Key contributions include: Galactoseismology (studying galactic disk perturbations via SEGUE/Gaia data), equilibrium modeling of the Milky Way, orbital torus imaging techniques, dark matter substructure analysis, and simulations of disk-halo interactions. Recent work explores pulsar-based dark matter detection, phase mixing theory, and fuzzy dark matter dynamics.

Methodological innovations include the GalactICS code for equilibrium initial conditions, discrete spectral analysis of phase space, and MilkyWay@home distributed computing for stream reconstruction.
