Dr. Patel is a primatologist who has been working in northeastern Madagascar in Marojejy National Park every year since 2000, where he has been studying the behavioral biology and conservation of one of the most critically endangered primates in the world, the silky sifaka lemur (Propithecus candidus). He also serves as the Madagascar country field representative for the international environmental organization Seacology and as a member of the Madagascar Primate Specialist Group of the International Union for the Conservation of Nature (IUCN).
From 2012 to 2015 Dr. Patel served as the project director of Duke Lemur Center’s SAVA Conservation Project. His fieldwork has garnered considerable media attention, including several televised feature films (by the BBC, Dan Rather Reports, Animal Planet, Earth Touch). In April 2010, “Saving the Ghosts of Madagascar” made the cover of Smithsonian Magazine. In 2020, the New York Times featured LCF’s programs on the front page of the Science section. In 2021, Cornell University Alumni Magazine featured our programs as well (for the second time).
