Research Interests

At present I work for the Wildlife Conservation Society in Tanzania and am conducting conservation focused scientific research on cetaceans in the Western Indian Ocean.  I was awarded a Pew Fellowship for marine conservation in 2013 that is supporting this work.  We are focusing on conducting a national assessment of whales and dolphins along the entire 800km + Tanzanian coast using both visual and acoustic survey methods.  We are focusing work on the west coast of Pemba Island which appears to be an important area for cetaceans.  Much of the work is centered around research and conservation of Indian Ocean humpback dolphins which are probably the regions most endangered cetacean.

I have been involved in research and conservation of marine mammals, primarily in South and Southeast Asia, for about the last fifteen years. A large focus of my previous work has been river dolphins in Asia, especially the Indus River dolphin which is a subspecies endemic to Pakistan. Indus dolphins are classified as endangered by IUCN and they persist in a river system fragmented by dams and barrages and degraded by water diversion for irrigation. My work has been conducted in association with the Pakistani Ministry of Environment, WWF-Pakistan and the Pakistan Wetlands Programme, as well as with numerous Pakistani researchers. The goal of the research was to determine the population status and to understand the effect that dams and barrages have played in the dolphins range decline.  As the primary threat to the population is depleted and degraded habitat I have been examining in detail which aspects of the habitat influence dolphin distribution at both fine and large-scales with the ultimate objective of using this information to propose protected areas. I also have a long-term study to evaluate whether the Indus and Ganges dolphins are separate species using both molecular studies and morphometrics techniques.

In addition to my work in Tanzania and Pakistan I have been involved in work with river dolphins on the Brahmaputra River, India, in the Sundarbans of Bangladesh and was involved with the final efforts to save the Yangtze River dolphin in China. I have a long-term interest in training and facilitating biologists in Iran to establish marine mammal research and conservation programmes in the Persian Gulf and Arabian Sea.
