Alessandro Catenazzi, PhD - Associate Professor
My research interests are the systematics and conservation of Neotropical amphibians and reptiles, and the ecological dimensions of biodiversity. I work primarily in the Andes and the Amazon. I collaborate with colleagues in museums and other research institutions in describing new species and developing phylogenies of frogs from the mega-diverse eastern slopes of the Andes. I am interested in using phylogenies as a road map to compare and contrast physiological traits among species, As part of these investigations, my collaborators and I are studying thermal preferences, tolerance to heat, and the influence of temperature on physiological functions, in order to understand how climate warming will affect these animals. Finally, a major theme of my current research is exploring the effects of fungal disease on the ecology of amphibians, a group that is experiencing staggering biodiversity losses worldwide. After documenting the collapse of a species-rich amphibian assemblage, I am interested in developing strategies to mitigate the impact of the fungal disease chytridiomycosis on surviving species. I'm an Amphibian Red List Authority and an Associated Researcher with the Instituto Peruano de Herpetologia and with CORBIDI. I'm the current Half-Earth Chair with the E.O. Wilson Biodiversity Foundation.

Rachel Prokopius - PhD (July 2025)
I am a life-long Ohio resident, and have lived in two opposite corners of the state. Go Buckeyes (sorry, not sorry, Anne)! I received a Bachelor’s degree in Science with a chemistry minor from Northern Kentucky University, an area containing some of the highest amphibian diversity on the planet. During undergrad my research focused on macroinvertebrate bioenergetics and their contribution to the inner workings of lotic systems, as well as the conservation status of big-game fish in Caribbean waters. My macroinvertebrate research took me to Karlstad, Sweden for six months and factored into my Honors Thesis, which compared macroinvertebrate biomass and attributes between two biomes. I was also able to spend three weeks in Belize comparing presence and size of economically-important marine species between conservation and general-use fishing zones off the Belizean coast. My research interests are not necessarily limited to one group of organisms; I think all animals are freaking awesome! My Ph.D. work focuses on animal behavior and the connection between it and the conservation of various species and populations of organisms. My interests include niche partitioning, intra and interspecific competition and invasive species.

Jon Adamski - PhD candidate
Hey all! I am originally from northeastern Pennsylvania. I went to East Stroudsburg University (ESU), PA while using my GI Bill to pursue my Bachelor of Science in Biology. I conducted minor research while pursuing this degree that focused on exploring the range limits of two rare species, the eastern fence lizard and eastern worm snake, in northeast Pennsylvania. I continued at ESU to pursue my Master under Dr. Thomas LaDuke, where I primarily worked with the timber rattlesnake and ArcMap to measure how anthropogenic habitat features affect population size. Across both degrees I worked on many different projects to gain the most diverse background possible. These projects focused on Hymenoptera pollinators, raptors, songbirds, bats, bears, and many amphibian species. Ultimately, I want nothing more than to be a professor while working on meaningful research. My research interests include herpetology, entomology, conservation, ecology, education, and museum maintenance and preparation. I am studying chytrid transmission among various frog species in Peru as part of an NSF grant within the lab.

Gustavo Ruano - PhD candidate
I am a Biologist from Guatemala with an interest in amphibian ecology in the Neotropics. During my undergraduate studies at the Universidad de San Carlos de Guatemala – USAC, I investigated salamanders and bromeliads interaction. After graduating, I was awarded the OAS scholarship to gain a master’s degree in Brazil at the Universidade Federal de Alagoas -UFAL; I researched bromeligenous amphibians and their risk of infection with the chytrid fungus in the Northeastern Atlantic Forest of Brazil. My current research interests are the amphibian microbiome, host-pathogen interactions, and bromeliads micro-ecosystems. Bromeliad tanks are important for amphibians in
the current global change scenario, as environmental refuges from diseases, climatic change, and habitat loss. Understanding amphibian dynamics within this microhabitat could be fundamental for amphibian diversity in a global change scenario.

Kevin Rivera - Bachelor in Biology
I'm a biology student at the Universidad Nacional San Cristóbal de Huamanga (UNSCH) in Ayacucho, Peru. During my studies, I specialized in herpetology and worked on projects in different ecosystems in Peru. As an Associate of Profauna Silvestre Ayacucho and collaborator with Conservación Andina, I am committed to the research and conservation of our local biodiversity. Currently, I have started working on my thesis, which will be located in the Relict High Andean Forests of the Historic Sanctuary of the Pampa de Ayacucho . In these ecosystems, which are still relatively understudied at this moment, I will study the diversity of amphibians and reptiles as well as their habitat preferences. In addition, I will research species interactions and the influence of the environment on the distribution of herpetofauna. With my research, I hope to learn more about local species and develop concrete strategies to conserve them

David Burkart - MS (December 2015, SIUC)
I come from North Carolina, home of everything great and wonderful from Krispy Kreme donuts to the world's highest salamander diversity. Luckily it was the latter, not the former, that caught my interest during my formative years and inspired my passion for nature, particularly, herpetology. I received my B.S. in Biological Sciences from N.C. State University. Following my graduation, I pursued varied dreams by conducting field work in both the southeast and South America in between touring the United States in a rock and roll band. My interests in both herpetology and conservation channeled my pursuits towards studying chytridiomycosis, eventually leading me to the Catenazzi lab at SIU. Here I have focused my efforts on the natural methods that make frogs resistant to the disease and how these can be applied towards mitigation strategies. In particular, I am investigating why two closely related species of marsupial frog differ in their response to chytridiomycosis - one is resistant and one susceptible. Using analytical techniques like mass spectrometry and next generation DNA sequencing, I identified the compositions of each species' antimicrobial peptides and cutaneous bacterial symbionts, two amphibian defense mechanisms that have been linked to chytridiomycosis resistance.

I am a freshman and a Physiology major on the Pre-Medicine track. In the past, I was involved with the IJAS Science Fair, and I researched the effects of spices on the growth if E. coli. I love going to new places and taking pictures throughout my travels, and I one day hope to visit all 50 states. In the lab you can find me preparing plates for PCR. |
Isaac Harris
I am a freshman hailing from Carbondale pursuing my degree in zoology and a minor in environmental studies. I hope that when I finish with school, I am able to pursue a career in park and recreation management. I enjoy being in nature, taking photographs, and playing basketball. While working in the lab I am normally preparing plates for PCR. |
Nathan Hooven

I have been involved with research on recent amphibian declines due to chytridiomycosis infection using quantitative PCR. I'm interested in the ecology and management of mammals. Now Master student at The University of Kentucky. |
Undergraduate researchers 2014/2015 (SIUC)
Shannon McQueen
I'm a junior in the animal biology track for zoology. My favorite animal is the polar bear,Ursus maritimus. As an undergraduate assistant in the lab, I have been involved in a variety of projects including preparing samples for stable isotope ratio mass spectrometry, PCR and real time PCR, and peptide quantification. I am also starting to work on a collaborative project between the Catenazzi and Fisher labs involving mammalian cell tissue cultures and toxicity assays. |
Dan Sears
I am currently a second year student working towards a Science Degree in Zoology with a specialization in Wildlife Biology and Conservation and a minor in Environmental Studies. It should not be a surprise that wildlife conservation is a field I find particularly interesting and hope to pursue in the future through graduate studies. As an undergraduate assistant, I mainly aid in prepping Bd swab samples for PCR. Also, I have helped with David Burkart's microBCA assay for his graduate work and inputted the Peruvian sample data in a spreadsheet. |
Cody English
I'm a volunteer undergraduate assistant. I assist with PCR analysis and any other areas where help is needed in the lab. I major in zoology and would like to pursue a career in conservation. |
Julie Driebergen
I'm a junior in Zoology and Geology with a minor in Creative Writing and I am also the president of the SIUC Chapter of the Wildlife Society and Zoology Club. For graduate school, I hope to study paleontology pertaining to early amphibians or early mammals/synapsids. In the lab, I help with PCR and I listen to recorded audio for frog calls. |
Megan Colburn
I am a sophomore majoring in zoology, and I hope to go to veterinary school when I graduate. In veterinary school, I hope to specialize mainly in reptiles. In my free time I like to play guitar and ukelele, play video games, and spend time outside. While working in lab, I prepare plates for PCR and microBCA, as well as enter data. |
