Research Interests

My research focuses on examining host defense responses in the airway in diseases such as asthma and copd as well as how inhaled pollutants alter these responses in exposed humans. My recent interests include examining the effects of vaping on lung macrophages and how macrophage immunometabolic profiles change depending on their anatomic location in the respiratory tract. Finally, my research includes establishing and maintaining the CEMALB Biorepository, where we house over 10,000 biological samples for research interrogation.
