Research Area: Human health and performance

While animal models have lead to huge advancements in our understanding of neurobiology, there is controversy over whether overexpression/silencing of gene expression is representative of diverse disease states. Indeed, the lack of availability of primary human neurons has made evaluating the pathological consequences of genomic mutations arduous. The use of human induced pluripotent stem cell (hiPSC) technology overcomes these limitations by providing a source of human neurons from both normal and disease genetic backgrounds. We currently focus on stem cell based models of Parkinson's Disease (PD) to study how mitochondrial stress mechanisms impact on neuronal function in human disease.

We currently have several projects in various areas that explore aspects of the gut microbiome and beyond:
1) Understanding how gut microbes are involved in the modulation of disease in colorectal cancer, diabetes, infection, and inflammatory bowel diseases
2) Isolation and characterisation of hunter-gatherer people's gut microbiome in an effort to discover novel microbial species and understand their function
3) Characterisation of the non-bacterial microbes of the human microbiome and their functions
4) Building model systems to study human gut microbes in vitro and in vivo
5) The study of 'oncomicrobes' (in particular, Fusobacterium nucleatum), and the development of colorectal cancer.
6) Translation to the clinic - development of 'microbial ecosystem therapeutics'

My research program adopts a broad and integrative approach to the study of chronic musculoskeletal pain, incorporating both basic and clinical sciences. A major arm to my research program is investigating the underlying pathophysiologic mechanisms using both animal and human models. My research also aims to advance reliable diagnostic criteria (imaging, biomarkers) and physical assessment techniques (quantitative sensory testing, electromyography) that enable effective and reliable treatment and management strategies. By emphasizing transdisciplinary and multi-institutional collaborations, my research program will continue to inform future clinical and experimental initiatives in the field of chronic musculoskeletal pain.

The growth of neurons and their organization into circuits is a tightly controlled process that follows a series of well-defined steps. Once differentiated and integrated into networks, neurons also retain a remarkable capacity to rapidly change the arrangement of their connections in response to activity, a feature that is believed to critically support cognition as well as our ability to learn and retain information for long periods of time. Accumulating evidence strongly suggests that perturbation of the molecular interactions responsible for the growth of neurons, or the capacity of these cells to adequately respond to activity-dependent signals, contributes to the pathophysiology of different brain disorders. Our laboratory uses a multidisciplinary approach to explore these questions.

More than 4 million Canadians have arthritis and the number of people living with arthritis continues to increase year after year. Osteoarthritis involves multiple tissues and often includes cartilage damage, bone sclerosis and synovial inflammation. A pressing need remains for joint localized therapies and interventions that could slow or ideally stop this debilitating disease.
In our research, we use genetic and surgical models of spontaneous osteoarthritis (with old age) and post-traumatic osteoarthritis (following injury). We follow the progression of disease in a joint in order to better understand how proteins such as TRPV4, integrin alpha1beta1 and cilia influence chondrocyte signal transduction and thus the development of osteoarthritis.

Currently, there are several major areas of research focus including the study of basic fatty acid metabolism, understanding the association between plasma fatty acids and health outcomes, omega-3 fatty acids in the prevention of breast cancer, and examining determinants of health in the Guelph Family Health Study. In addition, related projects include the study of fats in brain health (concussion, Alzheimer's Disease), fatty liver disease, fatty acid metabolism, bone development and nutrigenomics.

My interest in clinical biomechanics and neurophysiology evolved during my years as a primary health care provider in chiropractic and acupuncture. Over two decades of clinical observation underscored the fact that these, and other commonly adopted conservative clinical therapies/interventions, have a profound impact on human physiology, the scope and mechanisms of which are still poorly characterized. I began private practice in 1992 where I quickly developed a fascination for the clinical enigma of chronic musculoskeletal pain, the most common form of which being chronic myofascial pain.

Skeletal muscle is a remarkable tissue which regulates many metabolic processes, generates heat and is the basic motor of locomotion allowing us to meaningfully interact with our environment. When a muscle is activated at various lengths it produces a given predictable amount of force. However, when that muscle is actively lengthened or shortened those predictions go out the window. We actually know very little regarding dynamic muscle contraction. My research program focuses on muscle contractile properties and gaining a deeper understanding of how muscle works. I use altered states to tease out some of these fine muscle details such as: Muscle fatigue, Aging, And Training.

Our research centres on the application of physical activity and other acute/chronic perturbations to human physiology to understand how and why the body adapts to these stresses. We take an integrative systems approach, with our work focusing on interventions and assessments of cardiovascular, respiratory and muscular physiology. Specific focus areas include projects to understand the effects peripheral blood flow manipulation, the consequences of particularly stressful exercise, and novel training methods to optimize targetted physiological adaptations. From a health perspective, we are interested in understanding how exercise can be used to prevent and control risk factors for cardiovascular and cardiometabolic disease.
