I am a PhD student in Astronomy & Astrophysics at UC Santa Cruz. I am interested in high energy astrophysics theory, and am currently working to understand (1) tidal disruptions of stars by massive black holes, (2) common envelope episodes and stellar mergers, especially in the context of GW sources, (3) accretion onto neutron stars in a dense medium, and (4) changing-look quasars. My advisor is Enrico Ramirez-Ruiz. I have also worked on understanding vacuum decay and de Sitter space in string theory with Michael Dine.
I did my undergraduate at Harvard in Physics and Astrophysics. I did work in experimental particle physics on the Higgs to WW decay channel with Joao Guimaraes da Costa, in cosmology on custering-mass/color relationships in SDSS galaxies with Daniel Eisenstein, and on resolving excess large-scale power and North/South differences in SDSS with David Schlegel. Before starting my PhD, I backpacked and taught at a school in India for nine months.

- Within academia and particularly in physics and astronomy, there are far fewer people from underrepresented groups in undergraduate majors, phd positions, postdoctoral positions, and professorships than are reflected in the demographic makeup of the US (and the world). The field needs to do something about this---this includes developing equitable and inclusive hiring, admissions, and grant and telescope proposal reviewal practices, as well as recruiting and retaining students from diverse groups in undergraduate and graduate education. Regarding this aim in astronomy graduate education, the AAS recently put out a report on the status of diversity and inclusion as well as their recommendations: https://aas.org/education/aas-task-force-diversity-and-inclusion-graduate-astronomy-education.
