We apply machine learning, time series, and other novel analysis techniques to solve complex problems in astrophysics and other research fields.

We study how the presence of nuclear radiation fields in the vicinity of the jet affects the cooling of relativistic particles. Ben Groebe has developed an analysis algorithm using ARIMA models that allows us to characterize systematic differences between the gamma-ray light curves of BL Lacs and flat spectrum radio quasars.
