Research & Publications

Research Summary

Dr. Hansel’s research focuses on understanding the determinants of health outcomes in obstructive airway diseases, including asthma and chronic obstructive pulmonary disease (COPD). In particular, she has focused on understanding the adverse health effects of low-level air pollution in homes of patients with chronic lung diseases. She is director of the Bridging Research, Lung Health & Environment (BREATHE) Center, and her work has been instrumental in showing that substantially lower pollutant concentrations found in homes not using biomass in developed countries are still an important contributor to respiratory symptoms in patients with chronic lung disease, such as COPD. In addition, her work focuses on identifying subgroups with increased susceptibility to pollution exposure and her work has also focuses on understanding clinical phenotypes of obstructive airway diseases. Understanding different factors, including environmental exposures, that may modify disease expression is critical to accurately targeting personalized disease management approaches.

Clinical Trials

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