Professor Girguis' focuses on understanding how marine organisms have adapted to their habitats, and how they respond to a changing world. His highly interdisciplinary, residing at the crossroads of ecology, physiology, and biogeochemistry. His lab uses molecular biology (e.g., genomics, transcriptomics, proteomics), as well as physiological and geochemical techniques (in situ and laboratory mass spectrometry) to examine the relationship between organismal ecology, physiology, and biogeochemical cycles. Professor Girguis and his lab also develop novel ocean instruments and samplers such as underwater mass spectrometers, underwater microbial fuel cells, and deep sea autonomous laboratories. Equally important, Professor Girguis is deeply committed to supporting scholars from underrepresented groups at Harvard and beyond by developing and supporting progams that earnestly improve diversity, equity, and inclusion. He co-founded a Harvard/high school internship program, leads DEI efforts in ocean sciences in the U.S. and abroad, and works closely with United Nations delegates to promote democratization of ocean sciences around the world. He received his B.Sc. from UCLA, and his Ph.D. from the University of California Santa Barbara. He did postdoctoral research at the Monterey Bay Aquarium Research Institute with Dr. Edward Delong on the growth and population dynamics of anaerobic methanotrophs.
