To date, my research program has focused on strategies used to execute safe movement during adapted locomotor tasks (steering, obstacle circumvention, obstacle stepping) and the role of vision in these tasks. I am also interested in exploring the impact of cognitive or brain function on locomotor control. Given the commonness of dual tasking in our daily living, I hope to map patterns of cognitive-locomotor interference for multiple adapted locomotor (e.g. obstacle circumvention) and cognitive activities (e.g. visuo-spatial cognitive tasks) and ascertain optimal training strategies for dual-task performance.

My research is primarily focused on understanding the regulation of mitochondrial bioenergetics, with a particular interest in studying fatty acid oxidation (breakdown of fat yielding energy) in skeletal and cardiac muscle. We also study human exercise performance as well as type 2 diabetes, heart failure, diabetic cardiomyopathy and various neuropathologies, all conditions that have been affiliated with alterations in mitochondria as a key event in the progression and/or development of the disease.

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.

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.

Our research is dedicated to understanding mechanisms that dictate healthy function of the human spine, and ultimately the causes and consequences of low back injury and pain. To do this we study the mechanics and physiology of the lumbar spine and its musculature. We use both human and animal models to understand different aspects of how spine movement is achieved and what "normal" movement looks like, the role of muscle in producing this movement and stabilizing the spine, and how the spine and muscle both adapt to injury and how they can be rehabilitated from injury.

The primary aim of my research is to better understand the mechanisms that control, and functional consequences of, sympathetic outflow at rest and during stress in humans with and without cardiovascular disease. To uncover these mechanisms, my laboratory employs direct intra-neural recordings of postganglionic sympathetic traffic, studying both multi- and single-fibre preparations. Additionally, we are also interested in understanding the mechanisms responsible for the large inter-individual variability in blood pressure responses to stress, as well as testing novel interventions to reduce resting blood pressure, a major modifiable risk factor for cardiovascular disease.
