My research is in the health and disease relevance of a family of G protein-coupled receptors. This work combines cell culture, animal models, and various pharmacological and biochemical signalling assays.

My research explores how early nutrition can permanently change metabolism, increasing the risk for diseases later in life. More specifically, we delve into the role of amino acids, creatine and vitamins in liver and intestinal metabolism and how early nutritional stresses can program metabolism. We use the surgically altered pig as a model for the human and trace nutrients through metabolic pathways using isotope kinetics.

My research is on how cells communicate with their environment. Specifically, I focus on the role and regulation of extracellular vesicles (EVs), nanoparticles secreted by all cells, in normal B cell development and the use of EVs in monitoring leukemia. I am also interested in the interaction between breast cancer cells and fat cells.

My lab investigates the effects of nutrition and exercise on body composition, focusing on fat, muscle and bone tissues in both pre-clinical and clinical settings. We aim to develop preventive strategies through nutrition and exercise to optimize body composition and improve health span.

The resource burden cardiometabolic diseases place on healthcare systems is staggering. My research group aims to better understand how and why certain foods, dietary patterns, and lifestyle choices promote health while others promote disease. Our research focuses on physiological and metabolic aspects of dietary sugars and fats that change with changes in lifestyle factors (e.g. sleep and exercise). We are also studying the impact of public health policies that are aimed at reducing obesity and chronic disease burdens in the Newfoundland and Labrador population (e.g. sugar tax).  

My research program primarily focuses on elucidating small RNA-guided post-transcriptional gene regulatory mechanisms underlying human health and disease. It includes cellular, molecular, and biochemical approaches coupled with functional genomics, aimed at characterization of proteins involved in small RNA function and gene expression, with implications in cell fate determination and death.

My research interests are focused on food chemistry/biochemistry with emphasis on bioactives from plant, animal and other sources.
Nutraceuticals, functional foods and dietary supplements constitute the core of this programme and these include phenolics and polyphenolics, natural antioxidants, omega-3 and other specialty oils, lipid oxidation, lipid biotechnology,  protein hydrolysates and biopeptides, bioactives in health promotion and disease risk reduction, seafood (fish, shellfish, marine mammals), by-product utilization in zero-waste circular economy, aquaculture and process induced chemical changes in food.

I study Life-Sciences Pedagogy in the context of Higher Education, with a focus on long-term retention and transfer, metacognition, inclusive and Universal Design for Learning (UDL), and the impact of student health and lifestyle on various aspects of learning. My work ranges from the Scholarship of Teaching and Learning (SoTL), with studies examining the impact of instructional strategies within courses, to broader, longitudinal studies that explore impacts on learning within and beyond academic programming.

My research uses multiscale computational modeling to obtain high-resolution dynamic structural and mechanistic information about biochemical processes. Specifically, I am interested in understanding the structure and function of glycosyltransferase enzymes and the effects of the resulting glycans on modulating biochemical processes related to human health and disease.

I do research in fish endocrinology with a focus on the regulation of food intake and reproduction. My work ranges from in vivo treatments and behavioural observations to molecular biology.
