Research Activities

I have completed my post doctoral study from USA after completing PhD and Master Degrees from India in Marine Biology. I have more than 25 years research experience in marine environmental studies and marine fisheries covering the geographical regions such as: Arabian Sea, Bay of Bengal, Arabian Gulf, Red Sea and Puget Sound (Washington, USA). Currently, I am working as Research Scientist I/ Professor in the Marine Studies Section of Center for Environment and Water, Research Institute, King Fahd University of Petroleum & Minerals (www.kfupm.edu.sa), Dhahran, Saudi Arabia.


During 1986-2008, I worked as Senior Scientist and Principal Scientist in the Central Marine Fisheries Research Institute in India. I have proven ability to work in a team to achieve organizational goals in a multi-cultural, multi-ethnic environment with sensitivity and respect for diversity. I have published around 60 peer reviewed research papers and attended several symposiums, conferences, workshops and public consultations and presented scientific papers, lectures and speeches in national and international venues.
