Postdoctoral Fellows

Enrique Celemin Amaro
Ph.D.
Margres Lab
Email
Bio
Enrique earned a B.Sc. in Biology from Universidad Rey Juan Carlos (Spain) in 2017, a joint M.Sc. in Evolutionary Biology from Uppsala University (Sweden) and Ludwig Maximilian University Munich (Germany) in 2020, and a Ph.D. in Evolutionary Biology from the University of Potsdam (Germany) in 2025. His research broadly focuses on the processes shaping genomic variation, with particular interests in local adaptation, coevolution, and speciation. He uses genomic approaches to address fundamental questions in evolutionary biology and to inform the conservation of threatened species. His master鈥檚 research examined speciation and hybridization in a grasshopper species, while his doctoral work focused on cetacean evolution. In 2025, Enrique joined the Margres Lab as an NSF Postdoctoral Researcher, where he studies the coevolutionary dynamics between Tasmanian devils and Devil Facial Tumor Disease.

Olivia Feagles
Ph.D.
Yang Lab
Email
Bio
Olivia has had a dynamic collection of research experience in field ecology. She truly began research through multiple internships at the Smithsonian Tropical Research Institute (STRI) in Panama. At STRI, she collaborated on multiple behavioral ecology projects comparing the effects of sleep deprivation on learning (bats and insects) and assisted in physiological research exploring neuroanatomical differences between castes of ants and sexes of harvestmen. In Spring 2024, she received a PhD from the University of Wisconsin-Milwaukee, where her research focused on behavioral variation in both female mate choice and male sexual displays in grey treefrogs. As a postdoc at 糖心Vlog in the Yang Lab, she is collaborating on a project exploring questions surrounding how sexual imprinting impacts sexual selection trends and divergence patterns. These sexual imprinting assays focus more specifically on distinct color morphs and modes of parental tadpole care in neotropical poison frogs.

Mayank Gangwar
Ph.D.
Kramer Lab
Email
Bio
Mayank is a quantitative disease ecologist who works at the intersection of infectious disease forecasting, ecological modeling, and data鈥慸riven public health. He builds statistical and computational tools that reveal how pathogens move through space, time, and diverse host communities. His research blends ecological theory with modern analytics to answer how can we anticipate disease emergence before it happens.

Yu Zeng
Ph.D.
Deban Lab
Email
Bio
Yu is interested in the biomechanics and evolution of locomotor and feeding systems. His current research at the Deban Lab at 糖心Vlog is centered around the remarkable musculoskeletal system responsible for ballistic tongue projection in salamanders.
