Research in my laboratory focuses on the effects of air pollution and other environmental pollutants on the cardiovascular and respiratory systems. We use both traditional as well as novel physiological approaches (radiotelemetry, HF echocardiography, physiological challenge testing) to determine not only the short-term effects of exposure, but also the long-term consequences on health, particularly in the development of chronic diseases (e.g. heart disease). Rodent models are used to study the effects of real-world air pollution concentrations on the central and local neural controls of the cardiovascular and respiratory systems that render a host susceptible to adverse health events. Newer exciting research is focused on public health aspects such as nutrition (e.g. vitamin deficiencies) and non-environmental stressors (e.g. noise, climate change, social disruption) as modifiers of air pollution health effects. These studies examine the epigenetic changes that occur in early life or during development that result in physiological effects and future susceptibility.
