Below are my most recently published papers. For a complete listing including preprints see the publications page. Sometimes I add a short non-techincal description here to accompany the paper.
We present a pipeline for performing the optimal search for the astrophysical stochastic gravitational that combines a number of innovative time series analysis methods.
We propose a novel method to probe the presence of non-tensor gravitational-wave polarizations traveling faster than light.
We describe GWPopulation, a hardware agnostic framework for performing population inference.
We derive a new formalism to eliminate a form of systematic bias in standard siren cosmology due to mismodeling the observability of electromagnetic counterparts.
We describe how improved reduced order quadrature bases and methods dramatically reduce parameter estimation run time.
Sometimes I like to write up notes on random topics, mostly on how to use bits of software or implementations I found fun. A full list can be found in the posts tab.
