Research Interests

Dr. Smith is Director of the Thermal and Microvascular Physiology Laboratory which focuses on human thermoregulation and physiological responses to environmental stressors.  Current research includes utilizing novel approaches, including microdialysis and laser Doppler flowmetry, for assessing dermal carcinogen absorption and elucidating key factors modulating absorption during occupational exposure in firefighters. Understanding carcinogen exposure routes is of fundamental importance in various occupational settings to inform risk mitigation strategies and improve long term health outcomes. Additonal ongoing lines of investigation include examining in vivo signaling mechanisms underlying thermoregulatory and microvascular dysfunction in primary aging and cardiovascular disease groups.
