Personal profile

Research Interests

In the context of acute lung inflammation and injury, my laboratory focuses on DNA methylation and gene expression as features that define T lymphocyte immunoregulatory phenotype and pro-repair function. Our data show that these epigenetic phenomena can potentiate resolution of acute lung inflammation and repair of lung damage. This work is also applicable to the study of aging as well as disease states outside the lung, including autoimmune conditions, malignancy, and organ allograft rejection.

I am a physician-scientist specializing in pulmonary and critical care medicine as well as internal medicine. I received an MD from the Northwestern University Feinberg School of Medicine, where I also completed residency and chief residency in internal medicine. I then undertook fellowship training in pulmonary and critical care medicine at the Johns Hopkins University School of Medicine before returning to Northwestern as a faculty member in 2015.

My clinical focus is in critical care (ICU) medicine. I have a particular interest in acute respiratory failure, the acute respiratory distress syndrome (ARDS), mechanical ventilation, and extracorporeal life support/extracorporeal membrane oxygenation. I also specialize in physician-to-physician consultation regarding medical diagnostic challenges as well as inpatient-based general pulmonary medicine.
