Research & Publications

Research Summary

Dr. McCormack is a pulmonologist with a research focus on the effect of air pollution, diet, and obesity on populations with underlying obstructive lung disease. She has been funded by the NIEHS and the EPA to conduct home and school-based environmental cohort studies to understand the effects of indoor air pollution on children and adults with asthma and adults with COPD.  Her work is largely focused in Baltimore City but has extended to rural areas of Washington State and Appalachia, as well as the Caribbean.  Dr. McCormack has conducted trials of dietary and environmental interventions to understand the effect of diet and obesity as modifiers of susceptibility to air pollution.  Her long term goal is to reduce environmental health disparities to improve the health of susceptible patient populations with underlying obstructive lung disease.

Clinical Trials

Dr. McCormack is participating in the LIBERATE clinical study for individuals who have difficulty breathing and suffer from severe emphysema. For more information, visit here
