TitleProfessor of Chemistry
Alessandra Leri teaches courses in organic chemistry, general chemistry, and environmental science. She originated a freshman seminar on the urban ecosystem and coordinates the program in Environmental Studies. Prof. Leri’s research interests include organic geochemistry, urban environmental science, and chemical education. Her work in organic geochemistry has helped to overturn the long-established paradigm of halogens as unreactive inorganic elements in terrestrial and marine environments.
Prof. Leri’s research group, composed entirely of MMC undergraduates, is actively working on a variety of projects, including bacterial analysis of NYC sidewalks and playground sandboxes, geochemistry of peat cores (which are important global reservoirs of carbon), and chemical composition of recyclable plastics. She has brought many students to the synchrotron facility at Brookhaven National Laboratory on Long Island for experimental “beamtimes.” Her students have presented their results at various undergraduate research symposia and earned an impressive list of accolades.
