Alessandro Catenazzi, PhD - Assistant Professor
My research interests are the systematics and conservation of Neotropical amphibians and reptiles, and the ecological dimensions of biodiversity. For the first line of research, 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 CORBIDI.

Alex Shepack - PhD Candidate
I hail from the land of Dunkin Donuts and traffic circles, the greatest state in the Union, Connecticut (sorry David). I recently finished my Masters in Environmental Science from the Yale School of Forestry and Environmental Studies examining the effect of urbanization on amphibian populations (w/ David Skelly). Prior to that I worked on oviposition site choice in gray tree frogs at the University of Connecticut (w/ Mark Urban). Since 2008 I’ve been working in Costa Rica with the Forman School Rainforest Project, a high school group focusing on biological monitoring. At FIU i’m excited to return to the Neotropics to work on my PhD. I’ll be studying amphibian community composition and rebounding populations in Bd enzootic areas. I’ll be focusing on the dynamics and genetic structure of rebounding populations, causes for rebounds and overall community structure changes since the declines began. For more info on my current or past research check out my website!

Anne Sabol - PhD student
I'm originally from Ohio (Go Bucks, right Rachel??), where I got my Bachelor's degree in Zoology from The Ohio State University. During undergrad I studied cichlid personality and UV vison and participated in an REU at Oklahoma State University, focusing on bluebird nestling ecology. I then got my Master's degree at the University of Michigan in Dr. Ben Dantzer's lab, studying prairie vole sociality. After graduating, I worked for the San Diego Zoo Conservation Research Institute in Hawaii studying the behavior of the highly endangered 'alala (the Hawaiian crow). During this project I realized I wanted to move my research more in a conservation direction, so I am excited to focus on combining conservation and behavior in amphibians for my PhD.

Rachel Prokopius - PhD student
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! I plan to focus my Ph.D. work 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.

Kenny Anderson - PhD Candidate in Kominoski Lab
I come from the original land of Dunkin Donuts, the state Connecticut wishes it was: Massachusetts (Sorry Alex). Last year I finished my Master’s degree in Biology at Western Kentucky University and my thesis was focused on the effects of mining on pond breeding salamanders as part of the Johnson Lab. I received my Bachelor’s degree from Gettysburg college where I worked in the Kerney lab on characterizing the skin microbiome of red-backed salamanders in relation to their resistance to chytridiomycosis. During my time in the Catenazzi lab my research will be focused on the effects of biodiversity and abiotic filtering on the prevalence of Bd. I hope to determine drivers of Bd distribution across the landscape that will provide important insight for future conservation efforts in landscapes with chytridiomycosis. Profiles: ResearchGate |

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.

Lina Agredo - Undergraduate student (Icesi University)
I am a soon to be Biologist with emphasis in Molecular Biology and Biotechnology from Icesi University located in Cali, Colombia. My research interests are Animal Physiology and Molecular Biology. I participated in a project that studied mechanisms of neuroprotection against ischemia, which later on became my undergrad thesis. I undertook the study of hypoxic pre-conditioning in cerebral primary cultures, learned various procedures and techniques such as MTT cell viability assay, immunofluorescence and immunocytochemistry. Although my projects have mainly focused on Lab related work, I am also interested in (and love) field work. I participated in the 2016 international Bird Fair of Colombia and have a general interest in Conservation and Ecology, specifically in Amphibians and diseases, which led me to the Catenazzi Lab. I analyzed measurements of field body temperatures during the summer of 2018.
