Current Lab Members

PhD student Kristina Cohen joined the lab in 2010, after training and working as a middle and high school science teacher. Kristina studies the evolution and development of hatching mechanisms and hatching performance. She divides her time between tropical and temperate fieldwork, molecular lab work, and electron microscopy. []

Jesse DeliaPhD 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. []

KW-5006-Laura-p300Universidad de los Andes MA graduate Laura Bravo Valencia joined the lab as an Intern (2012), returned as a STRI Fellow, and continues to collaborate with Jesse Delia on research in Panama, Colombia and Ecuador. She studies maternal care behavior in glassfrogs.

Julie JungPhD 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. []

Javier Mendez Narvaez

by Alejandro Montoya

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 developmental plasticity, evolution, and ecology of foam-nesting frogs that vary in their use of aquatic and terrestrial nest sites.

Su Jin Kim is a BU Biology student. She joined the lab in 2014 as a sophomore, initially analyzing videos of embryo behavior. Su is now 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.

AngellyRespirometry-p300Angelly 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.

BrandonGuell-KMW_0589adj-sBrandon Guell is a University of California, San Diego student who joined the Warkentin Lab through the STRI-REU program. He is studying developmental changes in hatching performance, hatching complications, and embryo behavior.
