From Montreal, to Ottawa, to Ann Arbor, and back to Montreal again: my career in mugs!
-JH
Principle Investigator

Jessica Head, PhD
I am an ecotoxicologist with expertise in developmental models (fish and birds) and toxicogenomics. My career has taken me through laboratories in industry (Pharmaceutical), academia (McGill, University of Ottawa, University of Michigan) and government (Environment Canada, National Oceanic and Atmospheric Administration). I'm thrilled to be at McGill and in my hometown of Montreal! I am motivated to do research by my fascination with molecular biology and my passion for the natural world. Research questions that I find compelling relate to how seemingly simple relationships between exposure to chemicals and toxic effect are modulated by 'real-world' complexity (e.g. multiple stressors, variable genetic background, species-differences, variable histories of exposure). The McGill Ecotoxlab explores the fundamental science behind these questions and works towards applying our expertise to solving problems in the field of ecological risk assessment and regulatory toxicology.

Current Lab Members

Emily Boulanger, technician and former MSc student
I have always been passionate about marine biology/ecology, more specifically aquatic wildlife. Recently, I have become fascinated with ecotoxicology and the effects contaminants could have on marine mammals, birds, and fish. Many contaminants can cause birth defects, malignant tumors, and other developmental disorders in living organisms. After finishing my M.Sc. degree, which involved looking at the effects of contaminated sediments on the early life stages of fish, I am currently working at McGill University as a research assistant/laboratory technician in Dr. Jessica Head's lab. This work allows me to interact and assist many students with their projects.

Hugo Champagne Marchand, PhD student
I am graduated in both kinesiology and wildlife biology, which express my interests in physiology and nature. I breed ornamental fish as a hobby, hence my interest in fish reproduction and contaminants’ effects on fry. My research focuses on the early life exposure to polycyclic aromatic hydrocarbons and agricultural pesticide runoff on fishes. I have the opportunity of working with the copper redhorse, an endangered fish endemic to Quebec, which has a spawning season that coincides with a major agricultural flush of herbicides and pesticides.

![]() Yeonseon Jeon, PhD student Watching birds has widely altered my thoughts, career, and life. The hobby led me to get interested in ecology and population genetics, to join the molecular ecology lab in Ewha Univ., South Korea, and finally to join this ecotoxicology lab in McGill Univ., Canada. My current studies are built around the transcriptomic and histological effects of ethinylestradiol exposure in birds such as Japanese quail and double-crested cormorant.

Elena Legrand, Post-doctoral fellow
Daughter of sailors, I grew up with stories about the ocean. I naturally became interested in marine biology and ecology, and then in understanding the impact of chemicals in aquatic and marine organisms, which I specialized in my M.Sc. and PhD. During my PhD, I investigated the effect of endocrine disruptor compounds in an estuarine copepod. I discovered the ‘omics tools which I have been using in all my postdoctoral research projects. After working at the University of Maryland Center for Environmental Science - Institute of Marine & Environmental Technology, in Baltimore, MD, USA and the National Institute of Standards and Technology - Hollings Marine Laboratory, in Charleston, SC, USA, I am really happy to have joined Pr Jessica Head’s lab in Montréal, where I am investigating the molecular effects of chemicals in diverse aquatic and marine species as well as expending my horizon in avian toxicology.

Jonathan Sangiovanni, MSc Student I was initially drawn to science to understand the chemistry behind the everyday molecular interactions in my previous career in the culinary world. Yet, keenly aware of the ongoing global shifts in climate and the effects of human activity on diverse habitats, I was instead compelled to contribute to progress in environmental research. Since, I graduated with honours from McGill University in Environmental Biology, ever favouring an interdisciplinary approach that included stints in both plant science and microbial ecology labs. Now a Master’s student in Dr. Head’s lab, my present work focuses on the molecular mechanisms underlying differential sensitivity among bird species to polycyclic aromatic hydrocarbons (PAHs) exposure.

Paul Béziers, Post-doctoral fellow
PostDoc Mobility fellowship – Swiss National Science Foundation
I am an evolutionary biologist and ecologist, interested in understanding how organisms deal and adapt to the challenges that are inherent to their life and environment. My research line focuses on evolutionary endocrinology and ecotoxicology. I work with wild birds and domesticated species and use techniques from endocrinology and quantitative genetics to behavioural observations. I am mostly interested in questions related to stress physiology, environmental contaminants and fitness.
