Research Interests

My primary research focus is conservation-focused research on marine and freshwater cetaceans in Asia and Africa. In 2013 I was awarded a Pew marine fellowship that addressed the challenge that the greatest numbers of at–risk marine mammals populate the coastal waters of tropical developing nations.  Basic information such as species presence or absence is lacking along tens of thousands of kilometers of coastline in many of these areas, so important conservation issues are frequently missed. I designed and tested a marine mammal rapid assessment in Tanzania that allowed for broad–scale spatial data on marine mammal populations to be quickly generated at a national or regional level. The information gathered is helping to identify further research needs and address critical conservation efforts in the Tanzania region, a significant but poorly understood area.

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.
