Research

I am interested in the complete “story” of exoplanets: how different kinds of planets form and evolve (possibly even evolving into something that can host life!), and how we can observe this process. This leads to my interest in protoplanetary and debris disks (including our own Kuiper Belt), planet characterization, and planet demographics. I am also interested in the intersection between exoplanets and solar system science, using what we know from our own solar system to understand distant systems (and vice versa). In my career so far, I have mostly been looking at these topics through the lens of high contrast imaging, studying the population of young, large semimajor axis giant planets and brown dwarf companions.

   Gemini Planet Imager - Studying Debris Disks
   As a grad student at UCLA in Prof. Mike Fitzgerald's group, I've recently started working as part of             the Gemini Planet Imager collaboration! I'll be characterizing a debris disk from the survey - more           info soon!

   Speckles in High Contrast Imaging
   For my first and second years of grad school, I worked with Prof. Mike Fitzgerald and collaborators at       UCSB on a new tool to remove speckle noise from high contrast imaging data, with the goal of using     this tool to find fainter exoplanets. Results and more info coming soon!

​New Horizons - NASA's Pluto-Kuiper Belt Mission
Starting as a part of STScI's Summer 2017 student program, I worked with data from the New Horizons mission to better understand nitrogen - the dominant component of Pluto's surface and atmosphere - and the factors that influence its transport across the surface, through an analysis of the LEISA infrared hyperspectral data and related composition maps, as well as volatile transport modeling. My initial presentation for the summer program can be viewed on STScI's archive.

Project 1640 - Toward Exploration of Other Worlds
Beginning as an REU student at the American Museum of Natural History in Summer 2016 under the supervision of Dr. Rebecca Oppenheimer, I was a part of Project 1640, a high contrast imaging instrument at Palomar Observatory in CA, used to conduct a survey of nearly 200 nearby stars to search for exoplanets and brown dwarfs. I have worked on various aspects of the survey, including selecting targets and staffing observing runs with the instrument, processing data, and spectral characterization.
