Barb Katzenback.

Barb Katzenback

Assistant Professor

Current research in my lab focuses on host-pathogen-environment interactions and applies an interdisciplinary approach to evaluate how environmental stress influences the immune system, and health, of animals at the organismal, cellular and molecular levels.

Lauren Todd

NSERC Post Doctoral Fellow

My research interests include non-coding RNA-based mechanisms that regulate of gene expression as it relates to the host-pathogen interactions in wildlife infectious diseases. My current research as an NSERC Postdoctoral Fellow focuses on microRNA-mediated regulation of the amphibian immune system in response to Frog Virus 3 infection.

Alexander Douglas

Alexander J. Douglas

PhD Student

I began research for my thesis in Fall 2019. I am working to assemble a transcriptome of North American wood frog skin and isolate transcripts of novel antimicrobial peptides (AMPs). I will be investigating the effects of these AMPs on a panel of microbes, the epizootic amphibian pathogen Frog Virus 3, and cultured frog cells.

Research Technician

As a research technician in the lab, I am involved with a number of projects with primary focus on exploring the interaction between frog cells and Frog Virus 3, and detection of fish/amphibians and amphibian pathogens in eDNA samples.
