Dans le but de limiter la croissance impressionnante qu’a connu la population de la grande oie des neiges à la fin du XXe siècle, les autorités concernées ont libéralisé les règlements de chasse pour cette espèce au Canada et aux É.-U. en 1999 et 2009, respectivement. La chasse serait un outil efficace pour limiter la […]

Arctic temperatures are increasing twice as fast than the global average. In fjordic ecosystems of Svalbard, the Atlantification, the process leading to warmer conditions in the area impose new challenges to Arctic living community. Those changes alter cryosphere regime (i.e., ice component covering the surface) and associated species habitats. The black-legged kittiwake is a predator […]

Mesenchymal stromal cells (MSC) hold promise as cell-therapy candidates for numerous diseases such as Graft v. Host disease due to their ability to influence the immune system. MSCs have been shown to be capable of a broad range of immunomodulatory effects, including the production of factors that allow them to serve as Medicinal Signaling Cells […]

La majorité des essais nutritionnels sont réalisés chez des porcs nourris deux fois par jour avec une quantité restreinte de nourriture. Ces conditions ne sont pas représentatives de la régie alimentaire des élevages commerciaux où les porcs mangent plus de deux repas par jour sans limitation de la quantité ingérée. Or, la féquence et la […]

Recent scientific breakthroughs have led to the development of methods to differentiate human PSCs (hPSCs) into skeletal muscle cells. This has allowed, for the first time, the development of cellular models to study muscle diseases such as Duchenne Muscular Dystrophy and the possibility to utilize these cells for cell therapy applications. However, the reliability, efficiency […]

It remains unclear which factors drives variation in the gut microbiome across humans. Past work has taken an evolutionary perspective and compared the gut microbiome of humans on Western diets to wild primates and humans on non-Western diets and identified particular microbes which are at different abundances. However, the focus of these studies has mainly […]

The intention of this project is inquiry into the role of force signaling in skeletal muscle repair. Before muscle damage, muscle stems cells that are yet to be incorporated in the muscle fibers are relatively inactive, but when injury occurs they can multiply and are recruited to the site of damage. Many aspects of the […]

Diseases and injuries can affect essential activities of daily living like holding objects or walking. Investigating ways to optimize motor learning and performance is important for patient (i.e., stroke patients) and healthy populations (i.e., athletes). Exercising muscles to fatigue on one side of the body may improve motor tasks executed by the opposite limb. This […]

The heart beats 3-4 billion times in a person’s lifetime, making it the only part of the body that continues to work – without a break – for one’s entire existence! For this to occur, the heart must be highly regulated, so that is continues to function normally. Much of this regulation occurs within the […]

My research focus is shorebird ecology and conservation. Shorebird populations are declining globally, likely as a result of environmental changes and the expansion of human development. These birds are particularly vulnerable to habitat loss or degradation at their coastal wintering sites where they refuel from migration and prepare for their next breeding season. I will […]

The focus of this project is to screen for small-molecules that may interact with the machinery that controls the decision of life and death in the cell. Diseases can arise from aberrant control of cell life and death like cancer and neurodegeneration. By shutting off the cell death pathway when cells are injured, or stressed […]

Beef cattle play an important role in food production worldwide by making use of resources from which humans can derive little nutritional value to provide a nutrient-rich foodstuff containing protein, minerals and vitamins. However, greenhouse gases and ammonia that are produced by the cattle industry are associated with climate change. Producing nutritious beef that meets […]
