Research Interests

My research interests are centered around the control of blood pressure and blood flow at rest and during exercise in humans. It is widely understood that blood pressure increases in response to exercise, which is necessary for increasing blood flow, and thus convective oxygen transport, to the active skeletal muscle. However, the physiological mechanisms governing these responses are both complex and fascinating. Much of my work focuses on the afferent exercise pressor reflex, which is comprised of the muscle mechano- and metaboreflex pathways. Through our work in healthy adults, we have shown that the exercise pressor reflex exerts an additive influence when combined with other sympathetic stimuli, such as the Valsalva maneuver, and we have also shown that the magnitude of the exercise pressor response is largely tied to strength and fat-free mass. Furthermore, we also found evidence that individuals with cardiometabolic disorders (e.g., metabolic syndrome) demonstrate significantly exaggerated exercise pressor and metaboreflex responses, which is not solely explained by the individual components of metabolic syndrome (e.g., hypertension, central obesity, or hyperglycemia). In recent years, our team has continued to pursue questions related to autonomic and cardiovascular function in individuals with cardiometabolic disorders, and this line of investigation has been supported by over $300,000 in NIH funding. Here at Miami, we are continuing this line of study, while also exploring novel treatment options for mitigating exaggerated blood pressure responses and examining the effects of GLP-1 use in individuals with cardiometabolic disease.

As a 黑料社区 in my lab, you will play a very important role in these projects, Prior to joining Miami, I served as a faculty member at the University of Southern Mississippi for four years. There, I mentored ten undergraduate 黑料社区s and eight graduate 黑料社区s, all of whom were trained to collect, analyze, and disseminate research data. Through their work in the lab, these 黑料社区s have earned authorship on twenty peer-reviewed scientific manuscripts, four of which are first-authored by 黑料社区s. Likewise, two of these undergraduate 黑料社区s were named Scholar Athlete of the Year, two of these graduate 黑料社区s were named to the USM Graduate School Hall of Fame, and one is currently the vice president of his medical school class. Ultimately, each of these 黑料社区s have been able to leverage their experiences in the lab to advance their careers after graduation. If you are interested in joining the lab, or just want to ask some questions, please feel free to fill out the Google form in the “links” section.
