Current Lab Members
PhD student Jesse Delia joined the lab in 2011, after a Masters at East Carolina University with Kyle Summers. Jesse studies parent-embryo interactions, sexual selection, hatching plasticity, and the evolution of parental care in glassfrogs. He has studied glassfrogs in Mexico, Ecuador and Peru, and currently works mainly in Panama and Colombia. [email@example.com]
PhD student Julie Jung joined the lab in 2015 after a BA at Williams College. She is interested in how animals use information. Julie studies vibration-cued hatching in red-eyed treefrogs. [firstname.lastname@example.org]
PhD student Javier Méndez Narváez joined the lab in 2015. He did his Masters at Universidad de los Andes, on thermal ecology of leptodactylid frog embryos in foam nests. He is interested in the underlying mechanisms, including phenotypic plasticity, that facilitate reproductive colonization of land by frogs. [email@example.com]
Brandon Güell entered the Warkentin Lab as a PhD student in 2017, after a STRI-REU project on red-eyed treefrog hatching performance and behavior in 2015. He is studying plastic intraspecific and evolved interspecific variation in the timing of key developmental events that affect embryo escape-hatching in Agalychnis callidryas, Agalychnis spurrelli, and possibly other species. He did his BS in Ecology, Behavior and Evolution at UC San Diego, where he worked in collaboration with NOAA’s National Marine Mammal Lab studying foraging ecology and behavior of northern fur seal pups on the Pribilof Islands.

Luis Alberto (Beto) Rueda Solano began his PhD in January 2017 at the Universidad de los Andes. Beto is a professor of herpetology at Universidad de Magdalena in Colombia. His integrative PhD research on Atelopus is co-advised by an international team: Andrew Crawford (UniAndes, Evolution), myself (behavior, biotremology), and Carlos Navas (Universidade de So Paolo, ecophysiology). A central focus of Beto’s research in my lab is investigating vibration-cued foraging behavior in nocturnally active Atelopus.
Universidad de los Andes MA graduate Laura Bravo Valencia joined the lab as an Intern (2012), returned as a STRI Fellow, and collaborates with Jesse Delia on research in Panama, Colombia and Ecuador. She studies maternal care behavior in glassfrogs.
Team Treefrog Interns – 2017
Adeline Almanzar is a Boston University BA student in Behavioral Biology. She began in the Warkentin Lab analyzing other people’s videos of embryos hatching, then came to Panama to record her own escape-hatching videos to examine how development changes embryo behavior and escape success in snake attacks.
Rachel Snyder recently graduated with her BS in Ecology from Susquehanna University, where she studied salamanders. She is collaborating with Ana Ospina to study how development changes the way embryos use motion and tactile cues in their escape-hatching decisions.
Ana Ospina Larrea recently graduated as a BSc Biologist from Universidad del Quindio, Colombia, where she studied glassfrogs. She is collaborating on the multi-modal mechanosensory/biotremology project with Rachel Snyder, testing embryo responses to combined and separate presentation of motion and tactile cues at different developmental stages.
Team Treefrog Interns – 2016
Alina Chaiyasarikul is a BU Biology student. She joined the lab in 2015, analyzing videos in Boston. In summer 2016 she began using macro-video to study developmental changes in embryo behavior and escape performance in wasp attacks.
María José Salazar Nicholls, from the Pontifica Universidad Católica del Ecuador is interested in embryo behavior. She is collaborating with Karina Escobar to assess developmental changes in embryo self-rescue capacity, or the resilience of the hatching process and will also study glassfrog embryos in collaboration with Jesse Delia and Juana Rivera.
Karina Escobar, from Western Connecticut State University, is collaborating with María José Salazar, using manipulations of hatching embryos at different ages to assess developmental changes in the resilience of the hatching process.
Crystal Tippett, from Frostburg State University in Maryland, is comparing the process of spontaneous hatching and of early hatching induced by the slow, chronic threat of egg drying with the rapid “escape hatching” process induced by acute threats.
Juana Rivera Ordonez from the University of Washington is working with Jesse Delia on glassfrog behavior in the field, and studying effects of hatching timing on hatchling performance in several species of glassfrogs.
Su Jin Kim is a BU Biology student. She joined the lab in 2014 as a sophomore, analyzing videos of embryo behavior, and spent summer 2015 in Panama studying the development of the motion-sensing capacity of embryo ears, using the vestibulo-ocular reflex as an indicator of sensory function.
Nora Moskowitz graduated from BU in 2015 and joined the Warkentin Lab as a research intern in Panama. She is collaborating with Angelly Vásquez Correa to study how development changes embryo metabolism, in the context of hypoxia-cued hatching decisions.
Angelly Vásquez Correa is a Universidad de Antioquia student and research intern in the Warkentin Lab in Panama. She is is collaborating with Nora Moskowitz to study how development changes embryo metabolism, in the context of hypoxia-cued hatching decisions.
