As an undergrad I helped design a new online database of radio lightcurve data and updated/maintained the Supernova X-Ray Database (SNaX) for Professor Vikram Dwarkadas in the Astrophysics department.

Early in undergrad I worked as a lab tech in a geophysical sciences lab where I did some otimization work on the data processing pipeline for research on water isotopologue ratios in the atmosphere.

Way back in high school I did psychology research on project based learning and presented a poster at the National Association of School Psychologists with my collaborators.
