Research in the Meredith McCormack Lab deals primarily with pulmonary diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and the role of environmental exposures in lung diseases. We have researched the factors that contribute to inner-city asthma, with a focus on how particulate matter air pollution impacts pulmonary function. We are also part of the LIBERATE clinical study, which is focused on patients who experience difficulty breathing and have been diagnosed with severe emphysema. We also have a longstanding interest in the effects of race/ethnicity, poverty and urbanization on nutrition and food allergies.
