Rebecca Phillipson is a postdoctoral scholar working with Dr. Eric Bellm in the UW Department of Astronomy. Dr. Phillipson’s primary research interests are in the timing variability of accreting black holes and neutron stars using data from instruments onboard satellites such as the Rossi X-ray Timing Explorer, Swift, Kepler, and TESS in combination with ground-based optical observatories for spectroscopic follow-up. She is currently developing methods that accommodates unevenly sampled time series to study optical timing data from the Zwicky Transient Facility of unique compact binary systems. Dr. Phillipson employs methods from nonlinear dynamics and chaos theory for comparison to traditional Fourier-based techniques and Bayesian statistics as a means to create a new and complementary classification of transient and variable astrophysical systems. Her side projects include developing radiation-hydrodynamic simulations of the accretion disks around black holes and exploring interdisciplinary applications of novel time series analysis methods.
