Research Interests

My research focuses on fertility in men and how the father’s environment (diet, BMI & toxicants) impacts the sperm, clinical outcomes, development of embryos and offspring health. At the crux of this research is the sperm epigenome, a heritable layer of biochemical information that takes the form of methylation of DNA and the post-translational modification of chromatin associated proteins, the histones. The epigenome has been implicated in complex diseases such as infertility, cancer, diabetes, schizophrenia and autism. There is enormous potential in disease prevention and treatment via increased understanding of the establishment of the epigenome. We are interested in how environmental exposures to the father interacts with the developing sperm epigenome, and how this molecular information is transmitted to the embryo. We explore these research questions using transgenic mouse models to establish critical molecular underpinnings, which are then translated and studied in humans. Long-term goals are to develop fertility screening tools, and intervention strategies to improve child and adult health. We are currently developing e-health materials aimed at increasing men’s knowledge across the lifespan regarding lifestyle and fertility.

    • L’épigénétique est utilisée pour décrire l’information biochimique héréditaire au sein de l’ADN et des proteines qui entourent et régulent la condensation de l’ADN. L’information épigénétique régule l’expression génique et peut être influencée par l’environment. Nos modeles animaux nous ont permis de determiner que l’alimentation joue un role capital dans le programme epigenetique et la fertilite. Nos études des profils épigénétiques altérés dans des biopsies prélevées sur des patients atteints de cancer testiculaire ont mis en lumière la possibilité qu’une perturbation du programme épigénétique soit associée avec la survenue cancer. De facon interessante, nos travaux les plus recents montrent que les profils epigenetiques regulent egalement la pluripotentialite et la proliferation dans les cancers testiculaires et chez les cellules souches. Il est particulièrement important de mieux comprendre la contribution de l’épigénétique à la santé reproductive chez l’homme, puisque les modèles épigénétiques peuvent être perturbés par l’environnement et que les erreurs dans le code épigénétique peuvent avoir un impact à long terme sur la santé des hommes et de leur descendance.
