Research Areas of Interest:  Health benefits and potential mechanisms of post exercise hypotension (PEH).  My investigations attempt to determine the impact that a range of exercise durations and intensities plays in lowering the post exercise blood pressure in normotensive, prehypertensive, and hypertensive individuals.
