Ryan Almeida received his B.S. in biology from Davidson College in 2018 and his Ph.D. in ecology and evolution from Rutgers University in 2023. He is a conservation ecologist broadly interested in the causes and consequences of modern biodiversity loss. Almeida’s dissertation research centered on understanding mechanistic drivers of overexploitation in the global wildlife trade, with a focus on rare and valuable species. His work spans a variety of taxa and methodological approaches, and his recent study systems include global songbird trade, pangolin harvest, and herpetofauna trade in North America.
