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

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.

Nat Harper

Nathanael Harper

PhD Student (Co-supervised with Dr. Paul Craig)

My research focuses on validating eDNA methodologies alongside conventional taxonomic identification in local waterways.

Heather Ikert

Heather Ikert

PhD Student (Co-Supervised with Dr. Paul Craig)

My research investigates the impacts of multiple stressors on fish DNA & RNA production and release. For more information on my research please see my profile at



Alexander Douglas

Alexander J. Douglas

PhD Student

I began my M.Sc. studies in Fall 2019 and transferred to the PhD program in Fall 2020. My research aims to identify novel antimicrobial peptides (AMPs) from the skin of the North American wood frog, determine the factors that influence their expression, and describe their role in innate immune defence.

MSc Student (co-supervised with Mark Servos)

My research is focused on developing and using environmental DNA methodologies to characterize fish populations in remote Patagonian rivers.

MSc Student

I joined the lab as an Undergraduate Honours Thesis Student for the 2020-21 school year. I am currently in my final year of the Honours Biology program after previously receiving an Honours Bachelor of Computer Science with a Bioinformatics option.

My research will look at factors effecting amphibian wound healing using Xenopus laevis skin epithelial cell lines developed by the lab.

Co-op Student

I am joining the Katzenback lab this Spring as a fourth-year student in the Honours Biology Co-op Program with a minor in Anthropology. My research will characterize the potential antibacterial activity of four novel peptides identified by the lab, and their possible antiviral activity to Frog Virus 3.
