Derek E. Lee

Derek Lee (also known as Derek E. Lee or Derek Edward Lee) is an American ecologist and wildlife biologist specializing in population biology, conservation biology, and quantitative ecology. Lee is the principal scientist and CEO of the Wild Nature Institute, with ongoing long-term research regarding conservation demography and genetics of Masai giraffes in the Tarangire and Serengeti ecosystems of Tanzania.

His master's work was focused on migratory behavior of black brant geese in Humboldt Bay, using capture-recapture statistics to estimate stopover duration and space use. Lee's Ph.D. thesis-work studied the spatial demography of giraffes in the Tarangire ecosystem of Tanzania. His discovery of a white leucistic giraffe was widely reported in popular media.

Lee worked at Point Blue Conservation Science from 2002 to 2010 on Southeast Farallon Island, studying how ocean climate change affects the population dynamics of marine predators such as elephant seals, Cassin's auklets, and common murres. In 2010, he founded Wild Nature Institute, a research organization which he currently operates as CEO as well as principal scientist. From 2018 to 2024 he also worked at Pennsylvania State University as an associate research professor. Lee's research on the management of ungulate populations in Tanzania was the recipient of a Fulbright fellow grant in 2012 and 2013.
