Usha Rao, Ph.D.
Dr. Usha Rao obtained an undergraduate degree in Geology from St. Xavier’s College of the University of Bombay, India, prior to coming to the United States to earn a Ph.D. in Geochemistry at the University of Rochester. She was an Environmental Research Council post-doctoral fellow in Environmental Engineering and Geological Sciences at Northwestern University. Dr. Rao joined the Department of Chemistry at St. Joseph’s University in 2000, where she is currently an Associate Professor of Environmental Chemistry and Geochemistry. Dr. Rao’s classroom teaching has been recognized by a merit award for “exceptional achievement in teaching.”
At Saint Joseph’s, Dr. Rao is the Associate Director of the McNulty Scholars Program for Excellence in Science and Math, a scholarship and leadership development program for exceptionally gifted women students in the STEM disciplines. Dr. Rao also serves as a Board Trustee of the Ardmore Library of the Lower Merion Library System, one of the highest ranked library systems in the country. She has a long-standing commitment to projects promoting children's literacy and scientific literacy, providing invited reviews of approximately 100 new books each year and developing projects to enhance children's reading activities.

Dr. Rao’s research interests lie in the study of the presence of environmental pollutants in bodies of water, soil and sediment. At SJU, she and her students have evaluated the sources of salinity in a spring water system at Saratoga Springs, NY, and analyzed the bottom sediments of Lake Ontario for the presence of iodine radionuclides released during nuclear fuel reprocessing. More recent areas of research in Dr. Rao’s lab have included a study of the distribution of metals that were released to Pennsylvania’s streams during coal mining, and the study of atmospheric acid rain deposition-induced weathering in limestone headstones at Philadelphia cemeteries. Dr. Rao’s research has been funded by grants from the American Chemical Society-Petroleum Research Fund, the Lindback Association, Purdue University’s PRIME Laboratory, and multiple SJU Faculty Development Grants.
