Patient Care Setting



I primarily treat patients with pulmonary hypertension, heart failure, and pulmonary embolus (blood clots in the lung). My goal is to improve and provide access to care for patients with pulmonary vascular disease across New York and central Pennsylvania. We are a nationally accredited PHA (Pulmonary Hypertension Association) Comprehensive Care Center with an outpatient clinic and inpatient service at Strong Memorial Hospital. The URMC Pulmonary Hypertension group consists of my partner and mentor Jim White, MD,PhD; three full time nurse (Ali Theuer, Jenn Demarco, and Karen Frutiger); two research technicians (Deborah Haight and Jackie Bruno); a full time administrator (Jocelyn Dixon); and a post-doctoral research associate (Allison Light PhD). We are involved with multiple pharmaceutical clinical trials, translational research, and laboratory research.

Professional Background

I grew up in Ohio before moving to Philadelphia where I obtained my undergraduate degree (Biology) and was a collegiate rower at St. Joseph's University. I obtained my medical degree at the Philadelphia College Osteo Medicine. Afterwards I came to the University of Rochester for my internal medicine training and stayed for my Pulmonary and Critical Care fellowship. During my last two years of fellowship I joined Jim White's laboratory doing research on pulmonary vascular disease. I am now apart of the URMC Pulmonary Hypertension group that is a nationally accredited PHA Comprehensive Care Center.


I have been fortunate to work and collaborate with members in the division of Pulmonary and Critical Care Medicine at the University of Rochester Medical Center. Before focusing on pulmonary vascular disease I worked on improving detection of infections in immunosuppressed patients with pneumonia. Now I am working on developing biomarkers (extracellular vesicles and digital biomarkers) to help identify treatment response in patients with pulmonary arterial hypertension. This will allow for personalized medicine in this rare disease. We are also working on better understanding chronic thromboembolic disease by following up all submassive and massive pulmonary embolus admitted to Strong Memorial Hospital.
