I'm a postdoctoral researcher at the Jet Propulsion Laboratory and I recently finished my PhD under the direction of David Spergel in the Astrophysical Sciences Department at Princeton University. I like to think about testing theories of dark matter and dark energy with astrophysical data. I have also recently been interested in the gravitational waves produced by supermassive black hole binaries.

My research focuses on testing theories of dark matter and dark energy. Together, dark matter and dark energy make up over 95% of the Universe; however we still don't know their true natures. Astrophysical and cosmological observations are so far the only places we have observed either of these phenomena, and they remain the best places to test for their different properties.

I began my thesis work by considering novel tests of modified gravity. I tested Verlinde's Emergent Gravity Theory with dwarf galaxy velocity curve data and higher-dimensional theories for dark energy with gravitational waves.

I have now begun to focus on tests of dark matter particle theories. In collaboration with Harry Desmond and Pedro Ferreira (Oxford), I tested dark matter self-interactions using galaxy warps. I plan to continue thinking about particle dark matter tests in the future.

In my previous life, I worked on X-ray observations of dwarf galaxies to place limits on the number of supermassive black holes at their centers. This is one promising avenue for finding how supermassive black holes form.

I grew up in South Florida and completed my undergraduate degree in Physics & Mathematics at Furman University in 2014. In my spare time, I volunteer with all of the good doggos at the Pasadena Humane Society. I also enjoy rock climbing, running, and hiking.
