I am a broadly trained integrative physiologist. I use behavioral, neural, endocrine, ecological, and evolutionary approaches to study organismal biology in a variety of systems. Over the course of my career, I have worked with amphibians, reptiles, and mammals using both lab and field-based techniques. My background with comparative systems allows me to take advantage of natural systems that are tractable for discerning principles relevant to all vertebrates, including humans.
I teach Human Physiology, Cell and Systems Physiology Lab, Honors Thesis Research, and graduate courses in Conservation Physiology and Ecoimmunology. I infuse community-engaged learning practices in my courses and into the summer undergraduate research program.
Professionally, I am involved in the Society of Comparative and Integrative Biology, and I am Editor-in-Chief for the journal Herpetologica.

Effects of Environmental Stressors on Vertebrate Physiology and Behavior; Antimicrobial and Pheromonal Properties of Amphibian Skin Secretions; Science Education
Project 1: Impact of Environmental Stressors on Animal Health and Disease
Environmental factors such as pesticides, acid mine drainage, and climate change are potential stressors that disrupt physiological processes and behaviors essential to survival and reproduction. I examine the effects of environmental factors on vertebrate biology using amphibians as models. This work involves characterizing responses to both natural and manmade stressors, in the field and the laboratory. My work measures the effects of environmental factors on a variety of endpoints including gene expression, developmental rate, neurobiology, behavior, hormone levels, brain neuropeptide levels, intermediary metabolism, and immune function, including susceptibility to the amphibian chytrid fungus.
Project 2: Antimicrobial and Pheromonal Properties of Amphibian Skin Secretions
Amphibians have extremely glandular skin remarkable for the wide diversity of molecular structures and functions. I study amphibian skin secretions in three overlapping contexts: 1) the ability of amphibian skin secretions to inhibit microbial growth of bacteria that are relevant to human health; 2) the ability of amphibian skin secretions to inhibit growth of amphibian chytrid fungi that are contributing to serious declines of amphibians around the globe and 3) the role of amphibian skin in producing pheromones that have effects on behavior and physiology.
Project 3: Community-Engaged Learning
As part of an NSF REU Site Award, I am incorporating community-engaged learning into our summer undergraduate research program. This work is an extension of previous work that showed the efficacy of combining community engagement, novel research, and science communication in a classroom laboratory experience.
