I am an astrophysics PhD who recently graduated from Harvard University. I joined University of Chicago's geophysical sciences department as a 51 Pegasi b Postdoctoral Fellow in September 2021. My supervisor is Prof. Fred Ciesla.
While at Harvard, I worked with Prof. Karin Öberg (CfA) and Prof. Ilse Cleeves (University of Virginia) on modeling protoplanetary disk chemistry and physics. I also worked with Prof. Leslie Rogers (University of Chicago) on rocky planet interior structure modeling. I completed my undergraduate work at the California Institute of Technology in Pasadena, CA, where I worked with Prof. John Johnson and Dr. Leslie Rogers on exoplanet statistics. I have presented my work at American Astronmical Society meetings, the Kepler Science Conference II, and the International Astronomical Union's Astrochemistry VII meeting.
Many existing disk models do not take into account the changing physical conditions of the disk as material accretes towards the star. We seek to develop a self-consistent disk model that couples chemistry and dynamics in an efficient way.
Ultra-short-period, rocky planets can be pulled into non-spherical shapes by the extreme gravity from their host stars. We seek to model these shapes — and the resulting transit light curves — numerically.
Simple exoplanet transit models can be enhanced by taking into account the finite integration time of observations using Fisher information matrix analysis. Errors on each parameter are amplified in a predictible way, which can aid in estimating optimal exposure times.
