After working as an investment banking analyst in New York City, I switched careers in 2011 to pursue my passion in atmospheric science. Through research experiences at Stony Brook University, Colorado State University's CHILL Radar Facility and NASA's DEVELOP Program, I have become especially interested in the modeling of cloud processes. I received my Master's degree in 2016 with a thesis titled "Latent Heating and Aerosol-Precipitation Interactions within Mesoscale Convective Systems" and my PHD degree in 2020 with a dissertation titled: "Observations of aerosol particles and deep convective updrafts and the modeling of their interactions" under the the co-advisement of Professors van den Heever and Kreidenweis. After my PHD, I became a post-doctoral fellow at the Cooperative Institute for Research in the Atmosphere (CIRA), where I collaborated on various projects from NOAA's Global Systems Laboratory and Atlantic Oceanographic & Meteorological Laboratory's Hurricane Research Division. After my post-doctoral position, I was hired as a Research Scientist in the van den Heever group to work on the NASA INCUS Mission. My research focuses on understanding processes related to convective clouds and their microphysical and dynamical properties using high-resolution modeling and observations, including in situ and radar. In my spare time, I enjoy playing tennis, soccer, hiking, biking, and spending time with my family and friends.

| In 2017, we received some internal funding to purchase and install an OTT Parsivel Disdrometer on the roof of the Atmospheric Science Main Building at the CSU Department of Atmospheric Science (Foothills Campus). This instrument optically measures the precipitation number and fall speed size distributions, as well as a number of other precipitation parameters. We have been archiving this data since June 2018. The disdrometer has also been deployed to the PRECIP and BACS field campaigns. |
