I am a CIERA Postdoctoral Fellow at Northwestern University's Center for Interdisciplinary Research and Exploration in Astrophysics. You can find my CV here. I write a lot of code; you can see some of it in my various GitHub repositories.

Research Interests

Secular Planetary Dynamics
I am interested in the secular (i.e. long-term) dynamics of planetary systems, in particular secular chaos and the formation of dynamically-extreme configurations, such as hot Jupiters.
Parameter Estimation for Gravitational Wave Signals
I am a member of the LIGO collaboration, working on developing tools to determine the astrophysical properties of gravitational wave signals detected by the LIGO and Virgo instruments.
I am interested in the statistical analysis of astrophysical datasets, particularly randomized parameter-space sampling algorithms and model selection in a Bayesian context. I have applied previously discovered algorithms to gravitational wave parameter estimation (see above), and also to other astrophysical situations. I also sometimes develop new algorithms to support my work.
Advanced Mechanical Integrators
Variational and symplectic integrators for mechanical systems, particularly N-body systems.
N-Body Methods
Application to medium-N (N ~ 103--6) self-gravitating systems and to cosmological simulations.
General Relativity
Particularly SO(3,1) gauge-theory formulations. My thesis dealt with advanced integrators for numerical relativity that exploit the local SO(3,1) gauge freedoms of GR.
