My key research interest has always been to improve our understanding of neural circuitry, neuronal gene expression and neuronal behavior during acute or chronic stressors. I have long held a personal interest in researching cardiovascular disease as I was diagnosed in my teens with an inherited neurogenic cardiovascular disorder and my father died at a young age from cardiovascular disease. My academic experience and research training have provided me the opportunity to understand, in depth, cardiovascular disease progression and the effects of multiple other types of physiological stressors at the systems and cellular levels in the central and peripheral nervous systems. I currently have 12 peer reviewed publications and several more under review in this field. As an undergraduate student I was highly interested in understanding how stress hormones affect the brain to produce behavioral outcomes in animals and humans. I then worked for two years under Professors David Kreulen and Gregory Fink examining molecular changes in autonomic ganglia during hypertension. I completed my graduate research with Associate Professor Ann Goodchild understanding molecular mechanisms that contribute to hypertension, hypotension, hypoglycemia and hyperglycemia. Specifically, I used cholera toxin B neuronal tracing in combination with in situ hybridization and immunohistochemistry for neurochemical markers. During the next two years as a post doc I continued researching hypothalamic pituitary axis responses to physiological stressors including describing hyperglycemic responses to common medications prescribed for the treatment of hypertension. I have been complimented many times by reviewers in papers and by all of my three thesis reviewers for undertaking technically challenging and impressive work in the field of neuronal tracing and in situ hybridization/ immunohistochemical techniques. I additionally have collaborated on a number of studies looking at molecular mechanisms involved in the development and extinction of methamphetamine addiction as well as neurochemical identification of circuits regulating brainstem respiratory responses. My work directly contributed to one publication being featured as the journal cover image for its issue. I have presented my findings at multiple domestic and international conferences and I have trained and/or supervised a number of students at the undergraduate, masters and Ph.D. levels. I also ran the biomedical imaging facility within my department as a post doc, training and managing more than 100 people in our facility, and was instrumental in the success of our department obtaining >$450,000 in funding towards the purchase of a new high end confocal microscope. My current post doc position enables me to facilitate multidisciplinary approaches for studying biological challenges by using innovative novel technologies to enhance imaging capabilities- making nanoparticles and advanced microscopy techniques understandable and accessible to neuroscientists and other biologists. This includes integrating the latest advancements from the fields of microfluidics, biophysics, materials chemistry and photonics to help neuroscientists solve common challenges presented when imaging brain and spinal cord tissues.
