  • I have been teaching science courses on mineralogy, petrology, and geochemistry to undergraduate and graduate students for three decades at the University of Rochester.

  • I have served as an executive committee member of Volcanology, Geochemistry and Petrology, American Geophysical Union, 1998-2004. 

  • My research has yielded significant insights into continental flood basalt volcanism, their petrogenesis, and geochemical heterogeneities in the Earth’s mantle. Using Nd-Sr isotopes and trace element geochemical tracers, I have documented Mid-Miocene ridge-trench collision in California. I have also contributed to the understanding of arsenic release mechanisms in groundwater of the Bengal basin and on submarine groundwater discharge using Sr-isotopes as tracers with implications for the marine strontium isotopic budget.

  • I am a Fellow of the Geological Society of America, and the American Association for the Advancement of Science (elected 2004.

  • I have supervised the research of a number of undergraduate and graduate students, and provided training to several under-represented minority and women scientists.

  • I have been involved in outreach activities throughout my professional career in visiting schools, giving public lectures, all in efforts to promote the welfare of the geosciences.

  • I have advised the International Atomic Energy Agency’s Isotope Hydrology Division in studying groundwater Arsenic contamination in Bangladesh.
