I'm an exoplanet researcher specializing in yield modeling and mission simulation for future space telescopes. I'm currently a NASA Postdoctoral Program Fellow at Goddard Space Flight Center, where I work with Chris Stark on coronagraph simulations and direct imaging yield studies for the Habitable Worlds Observatory (HWO). I also co-led the Visualizations Task Group for HWO's Exoplanet Science Yield Working Group.

I spend most of my time building Python tools for the exoplanet community. These include coronagraphoto for simulating realistic coronagraphic observations, yippy for PSF interpolation, orbix for extremely fast orbit propagation, and yieldplotlib for visualizing what different yield calculators produce. I'm also a core developer of EXOSIMS, an open-source mission simulation framework created by Dmitry Savransky.

I did my PhD at Cornell with Dmitry Savransky, where I worked on the Roman Exposure Time Calculator and developed methods to use radial velocity precursor data for scheduling direct imaging observations. Before that, I studied fluids and flying snakes at Virginia Tech-the snake research being responsible for my most memorable lab incident.
