I am drawn to cardiac research by the sheer volume of those afflicted by debilitating cardiac disease. Heart failure is a near certainty if one lives long enough for the years of cardiac stresses (e.g., atherosclerosis, high blood pressure, etc.) to converge into decompensation. It is astounding to me that with all the money, people and time put into understanding heart failure over the last century, it still remains a largely incurable condition with most treatments focusing on the cardiac stresses rather than the direct cardiac remodeling. My interest is in improving our understanding of how the heart remodels to various injuries, and if these patterns of remodeling can be slowed, prevented, or improved to directly treat the cardiac dysfunction without alleviating the cardiac stress.
Investigating cardiac remodeling following acute (myocardial infarction) and chronic (pressure overload/aortic banding) cardiovascular stresses. Specific emphasis is placed on developing novel therapies to treat adverse remodeling.

While completing my undergrad in biomedical sciences at the University of Guelph, I was fortunate enough to receive an undergraduate research project scholarship in the summer preceding my 4th and final undergraduate year. I joined Dr. Jeremy Simpson's lab that summer and was immediately enamored by the research process. I quickly determined I was interested in a 4th year research project, and quickly following that enrolled as a masters student again under Dr. Simpson. With a year of grad school under my belt, I determined my goals were too large to be met in a Master program, and instead transferred into the PhD stream. Throughout my PhD, I have been involved in many projects outside of the original scope of my thesis, and in doing so have gained a great deal of appreciation for the time, determination and resources required to successfully complete high impact scientific research. I am presently finishing the 4th year of my PhD with the goal of completing my degree by the end of my 5th year. In the future, I look forward to exploring the business side or scientific research with the ultimate goal of directing the flow of funding into new and exciting projects with significant market promise/viability.
I am a huge sports fan with allegiances first and foremost to any Toronto based team (particularly the Leafs and Jays). I play in two ball hockey leagues year round, and in intramural ice hockey through the winter.
