Under the supervision of Dr. Kate Daniel, I have developed a novel method (PECCARY) for distinguishing between regular and chaotic orbits, as well as natural stochasticity and computuational noise in galaxy simulations. To do this, I am also creating a suite of various tracer particle simulations to test this method.

During my first few years of graduate school, I developed a first-order post-Newtonian astrometric and spectroscopic model to describe stellar orbits around black holes, under the supervision of Drs. Dimitrios Psaltis and Feryal Özel. The model was based on the well-known two-body model developed for the pulsar community by Damour and Deurelle in the 1980s, which we adapted for stars such as the S stars in the nuclear cluster in the Galactic Center.

Since 2018, I have been studying the 3C 220.3 galaxy system under the supervision of Dr. Belinda Wilkes. The system is comprised of two foreground galaxies at redshifts of around z = 0.685 that are lensing a submillimeter galaxy at a redshift of 2.2205. One of the foreground galaxies is a Type II radio-loud AGN. My work on this system includes spectral energy distribution (SED) modeling for stellar masses, X-ray analysis, magnetic field strength calculations of the radio lobes, and optical and near infrared photometry. The paper on the 3C 220.3 system is nearing publication, and a catalog paper on additional galaxies and stars from our MMT data is forthcoming.
