Research interests
- Critical Care
- Sarcoidosis
Additional Research Interests
Critical Care Research themes:
- Mitochondrial mechanisms of organ failure during sepsis
- Biomarkers for the early detection of sepsis in the hospital setting; particularly the monocyte distribution width (MDW), FDA approved (2020) for the detection of sepsis in adults admitted to the Emergency Department
Sarcoidosis Research themes:
- Genomic studies of granulomas to determine disease mechanisms and to identify novel therapeutic targets
- Clinical practice guidelines for the diagnosis and management of sarcoidosis
- We established the first tractable laboratory disease model
Current Research
- We are establishing novel biomarkers for early sepsis detection based on machine learning and employing the electronic medical record in conjunction with the US Government and FDA
- We are investigating novel therapies for COVID-induced acute lung injury
- We are conducting translational research in the field of pulmonary sarcoidosis to elicit disease mechanisms, establish novel biomarkers and to investigate novel therapies.
