Mark Marvin-DiPasquale, PhD

Dr. Marvin-DiPasquale is a Research Microbiologist for the USGS Water Resources Mission Area.

A native of Rochester NY, Dr. Marvin-DiPasquale is Project Chief of the USGS-Earth Systems Processes Divison (ESPD) effort "“Biogeochemical Cycling at Regional Scales”. He completed a B.S. in Chemistry at SUNY StonyBrook in 1987, and a Ph.D. in 1995 from University of Maryland, Marine and Estuarine Environmental Science Program, with a focus on the microbial ecology of Chesapeake Bay sediments. He began a career at USGS (Menlo Park, CA) as a ‘National Research Council’ post-doc in 1995, and became a Project Chief in 2004. During much of his USGS tenure, his research focus has been on mercury cycling in various ecosystems, including: the San Francisco Bay watershed and associated mining areas throughout CA; FL Everglades;  Carson River, NV (mercury Superfund site); coastal Louisiana; Pategonia region of Argentina; Puget Sound, WA; USGS-NAWQA and USGS-WEBB Study Units in OR, FL, WI, SC,  NY, CO, GA, PR, and VT.
