Ian started work in the Russell Lab during the summer 2023. He is a student at Washington University in St. Louis double majoring in Applied Mathematics and Economics with an interest in mathematical modeling. His work focused on generating back-trajectories, creating probability plots through a potential source contribution function, mode-fitting, and merging hourly aerosol size distributions using SEMS and APS measurements from EPCAPE. Additionally, he worked in the clean room running pre-scans using the FTIR spectrometer for use in the EPCAPE campaign.
