We are fortunate to work with excellent high school and undergraduate students! Mentoring students is an important component of our lab. Central to our mentoring philosophy is identifying the students’ goals to help them grow towards them. By developing a relationship founded on mutual respect, we promote a friendly and engaging environment for students to learn through inquiry.

Undergrads in the lab participate in projects  both at Purdue University (West Lafayette, IN) and at the Smithsonian Tropical Research Institute (Gamboa, Panama), where our main lab and field facilities are located. Some of our undergrad students have also been involved in research projects with us at other locations including field sites in Florida (USA) and Irimote Island (Okinawa, Japan).

Leonardo de Campos
Graduate Student


I am a doctoral student in the postgraduate program in Ecology at Universidade Federal de Santa Catarina, I hold a Master's degree in Ecology from the same program and a Bachelor's degree in Biological Sciences from the Universidade Federal do Paraná. I have experience in Macroecology and evolution, with emphasis on phylogeography, geometric morphometry and niche modelling, working mainly on the following topics: Conservation, diversity and distribution of anuran amphibians, ecological interactions and molecular ecology between Diptera insects and amphibians.

Katherine González
Graduate Student


I am a tropical biologist from the National University of Costa Rica. After graduating I studied the ecology and post-reproductive movements of a Neotropical toad in the tropical dry forest. More recently I worked with tree frogs in the Osa Peninsula studying adaptive embryo behavior and environmentally cue hatching. I am interested in exploring the roles that eavesdroppers play in anuran communication and behavior during mating aggregations. I also plan to investigate how predation and parasitism could be altered by the presence of heterospecific anuran signalers.

Stephanie Gutierrez
Graduate Student


I graduated from the University of Texas at Arlington in 2015 with a bachelors degree in Biology and Science Education. While earning my undergraduate degree I worked as a biology teacher at James Bowie High School and with the volunteer department at the Perot Museum of Nature and Science. As a graduate student at Purdue, I am co-advised between Dr. Bernal and Dr. Minchella. I am interested in studying the effects of trypanosomes on the behavior of anurans as well as the population biology, evolution, and genetics of host-parasite interactions.

Andrew Mularo
Graduate Student


I received my bachelors degree in Evolution and Ecology from Ohio State University, with a minor in Entomology. While there, I conducted research on the chemical ecology and population genetics of Neo-tropical ants, as well as worked as a seasonal park naturalist. Here at Purdue, I am interested in using genetic and behavioral approaches to study various aspects of population dynamics in túngara frogs.

Brian Leavell
Graduate Student

I come from Dr. Jesse Barber's lab at Boise State University where I studied sensory ecology, behavior and evolution within bat-insect interactions. Here, I have continued along these lines of inquiry while focusing on frog-biting midges. I am particularly interested in understanding the sensory ecology of frog-biting midges and the effects this micropredator eavesdropper has on sexual selection in anurans.

Ana Maria Ospina
Graduate Student
 I am a biologist from the Universidad of Quindio in Armenia, Colombia. I have been studying aspects of natural history, sexual selection, and parental care in anurans, doing field recordings and analyzing frog calls emitted in different contexts. After graduating, I worked at the environmental sound collection of the Humboldt Institute in Colombia. I am interested in exploring how acoustic signal production and/or perception might be affected by the introduction of novel disturbances associated with urbanization.

Dr. Shilpi Singh
Postdoctoral Researcher


I obtained my doctoral degree working at Dr. Joby Joseph's lab at the University of Hyderabad, India. During my PhD, I worked on the organization of the olfactory circuitry and computation in a grasshopper species, Hieroglyphus banian. Here, I am investigating the neurophysiological mechanisms underlying the eavesdropping behavior of frog-biting mosquitoes.

Dr. Richa Singh
Postdoctoral Researcher


I am interested in understanding how anthropogenic changes in the sensory environment alter animal behavior. During my Ph.D. at Dr. Manjari Jain’s Lab at the Indian Institute of Science Education and Research (IISER), Mohali, India, I studied how changing environmental factors affect cricket calling behavior. Here, I am interested in examining the effect of noise pollution on auditory neurons in frog-biting mosquitoes.
