Environmental Science Associate experienced in aerosol characterization, air quality monitoring, and atmospheric chemistry. Currently a first-year Ph.D. student in Atmospheric Science at Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS), focusing on nocturnal boundary layer dynamics, aerosol transport, and the impact of temperature inversions on air quality and radiative forcing.
As a member of the Aerosol Group at Brookhaven National Laboratory (BNL), I work with aerosol instrumentation and data analysis, including troubleshooting and processing data from the Aerosol Chemical Speciation Monitor (ACSM), serving as an associated mentor. COntributed to large-scale field campaigns, such as the ARM CoURAGE campaign and the Urban Threat Dispersion Project in NYC.
Passionate about environmental research, STEM outreach, and collaborative scientific efforts. Outside of academia, I enjoy music, sports, and sustainability initiatives.
