Principal Investigator

Dr. Vance Trudeau

Vance L. Trudeau was born and raised in Dartmouth, Nova Scotia, Kjipuktuk, Mi’kma’ki, the unceded territory of the Mi’kmaq People.

Trudeau received his BSc and MSc from McGill University and PhD at the University of Alberta under the supervision of Richard E. Peter. After post-doctoral training in Canada with Leo Renaud and in France with Dominique Poulain and Dionysia Theodosis, he took up his first academic position at the University of Aberdeen (Scotland). He later joined the Department of Biology, University of Ottawa in 1998.

Trudeau holds the University of Ottawa Research Chair in Neuroendocrinology (2011-2026) and leads a team of dynamic trainees with wide interests and talents. Worldwide collaborations are also fundamental to the advancement of our research and are deeply appreciated. His group's research is directed towards understanding how the vertebrate brain regulates anterior pituitary hormones that control sexual development and reproduction using fish and frog models. Applications of this basic research include spawning induction methods for endangered amphibians, among others. The team also studies the effects of sex steroids and pollutants (pharmaceuticals, pesticides, petroleum products) on development and reproduction in fish and frogs. This concept is called endocrine disruption. Research conducted by TEAMENDO.CA has implications for environmental and human health because many of these hormonal systems are conserved across species. This means that what is discovered in one species, has major implications in other vertebrate, including humans.

Trudeau was founding Vice-President of the North American Society for Comparative Endocrinology ( and is the current President of the International Society for Fish Endocrinology (

Teaching philosophy: to share the wonders of animal physiology and endocrinology and to help students at all levels to critically assess and conduct research on these topics. 

Hobbies: composing and playing music, hiking, fermentation biology, cooking

Graduate Students

Udeesha Erandani | PhD Candidate


Udeesha is a PhD student who studies the role secretogranin 2 and secretoneurin peptides in zebrafish reproduction. She uses a range of  approaches including gene editing, behavioural analysis and neuronatomy. Other than research, she likes to bake, crochet, travel and music as her hobbies.

Jeffrey Ethier | PhD Candidate


Jeffrey is a behavioural ecologist with a focus on acoustics and animal vocalizations. His current PhD research project focuses on the vocal behaviour of boreal chorus frogs (Pseudacris maculata). When he isn’t recording frog calls, Jeffrey can be found going for hikes, reading science fiction and fantasy novels, or fostering animals in need. He has a cat, Penelope, whom he adores.

Maddie Empey | PhD Candidate


Madelaine is a Ph.D. Candidate studying the effects of pesticides on amphibians. Her research aims to provide critically missing data on the impacts of Bacillus thuringiensis (Bt) and deltamethrin insecticides on Canadian frogs. Madelaine’s passions include herpetology, natural history museums, and spending time in nature. After her Ph.D., she hopes to continue a career in conserving Canada’s natural heritage and protecting species at risk through research.

Brianna Raven | PhD Candidate


Brianna is a PhD candidate that joined the lab in 2020. Her research is focussed on the reproductive neuroendocrine functions of kisspeptin and secretoneurin in the Western clawed frog, Silurana tropicalis. This research will be accomplished using methods including droplet digital PCR, immunohistochemistry, and RNA-Seq. Her hobbies include rock climbing, cooking, and exploring the outdoors.

Emmanuelle Monniez | PhD Candidate


Under the co-supervision of Drs. Vance Trudeau and Carole Yauk (GReAT lab), my research aims to determine the effects of developmental exposure to selective serotonin reuptake inhibitors (SSRI) on the regulation of the stress axis in zebrafish. I am investigating both long-life and transgenerational effects and will compare transcriptomic, physiological, and behavioural endpoints.

Victoria Spadacini | MSc Student


My research is focused on the activity of the secretoneurin-producing neurons in the zebrafish brain during the female ovulatory cycle. I am using neuronal activation biomarkers, with the goal to further illuminate the role of secretoneurin in the hypothalamic-pituitary-gonadal axis and in promoting essential reproductive processes in the zebrafish model.

Dinusha Rajapaksha | PhD Student


My name is Dinusha Rajapaksha. I am Ph.D. student working under Drs. Jan Mennigen and Vance Trudeau. I  investigate the role of oxytocin in zebrafish reproduction. I will explore the activation of oxytocinergic neuronal circuits and potential co-localization with other neuropeptides. 

Chunyu Lu | Post Doctoral Fellow


Chunyu Lu is a skilled postdoctoral fellow with a diverse background in engineering, analytical chemistry, and solid phase peptide synthesis. For this PhD, he investigated the role of the emerging reproductive peptide secretoneurin.  As a member of the TEAMendo group, he also provides critical analytical support for fellow lab members. Currently, research is focussed on an exciting conservation project in collaboration with Environment and Climate Change Canada. He wants to develop steroid analysis methods for large mammals such as caribou and bison.
