 Dr. Brian Trevelline - Postdoctoral Researcher
Dr. Trevelline’s research interests span the fields of molecular ecology, host-microbe interactions, and conservation biology. Broadly, Dr. Trevelline uses molecular approaches to investigate how wildlife respond to changes in resource availability and environmental conditions. For his dissertation, Dr. Trevelline used residual prey DNA in avian feces to show that anthropogenic stream acidification influences the behavior and diet of breeding migratory birds by reducing prey availability. Dr. Trevelline currently has two on-going studies investigating the influence of local environmental conditions on the diet and gut microbial communities of migratory birds wintering in the Caribbean. In the Kohl Lab, Dr. Trevelline uses molecular and metagenomic techniques to study how changes in diet affect the digestive physiology and gut microbiota of wild rodents.

Samantha Fontaine - Graduate Student

​Sam's research interests include host-microbe interactions, disease ecology, conservation biology, and herpetology. She is specifically interested in how environmental factors and anthropogenic stressors can affect the relationship between ectothermic hosts and their associated microbes, ultimately impacting animal physiology, ecology, and evolution. In the Kohl lab, Sam is studying the impact of temperature on amphibian gut microbiota, and the resulting functional effects on animal performance, which will be important in predicting animal responses to climate change. As an undergraduate at SUNY Oneonta, she studied disease dynamics in green frogs and wood turtles of upstate New York. Before beginning her graduate studies at Pitt, Sam was lucky enough to work on conservation projects involving threatened and endangered species such as eastern box turtles, Wyoming toads, and Kemp’s ridley sea turtles. 

Elizabeth Rudzki - Graduate Student

Elizabeth’s research interests encompass host-pathogen interactions, parasitology, disease ecology, microbiology, immunology, and developmental biology. Elizabeth is a student of both the Kohl Lab and the Stephenson Lab, and is studying the flatworm parasite Gyrodactylus in the Trinidadian guppy model and how the host’s infection susceptibility to this parasite relates to the host’s skin and gut microbiome. Prior to graduate school, Elizabeth worked as a research specialist at the University of Pittsburgh in Dr. Jon Boyle’s lab, studying Toxoplasma gondii and how it crosses the placental barrier during congenital infection. As an undergraduate at Edinboro University, Elizabeth researched the presence of angiogenic inhibitors in the hemolymph of corn furrow spiders, as well as assisted in a large-scale study of big game migration in Botswana.

Karen Peralta Martínez - Graduate Student

Karen is interested in host-microbe interactions, microbiology, genetics, and cellular biology. In the lab, Karen is studying how, under different diet strategies, the activity of the gut microbiota aids hosts with rapid physiological adaptations. She is excited to explore this question using a combination of metagenomics, cellular and molecular techniques. Before moving to Pitt, she worked as a laboratory technician under the mentorship of Dr. Clement Chow in the department of Human Genetics at the University of Utah. A central research focus of her job was to identify the impact of genetic variation on the outcome of N-Glycanase 1 (NGLY1) deficiency, a rare, autosomal recessive disease. As an undergraduate at Bucknell University, she studied chloroplast relocation in ferns grown in the dark and supplemented with cytokinin.

Jaclyn Adams - Research Technician

Jaclyn is interested in vertebrate conservation biology and animal health. She has worked at veterinary clinics, natural history museums, and volunteered at wildlife rescues and zoos. She holds a Bachelor of Science degree from Shippensburg University where she studied bird physiology and anuran behavior. Jaclyn also has a Master of Science degree from Eastern New Mexico University where she studied the landscape ecology of black bears. As a field technician at the Illinois Natural History Survey, she studied the demographics of threatened species, including amphibians, mussels, and snakes. She has also interned at the Bureau of Land Management in New Mexico, completely a census and demographic study of a federally threatened plant species. Jaclyn is excited to pursue gut microbiome research on frogs and tadpoles in the Kohl Lab.
