I'm a general cardiology fellow at the Heart Institute. I was drawn to this specialty by the intriguing physiology of the cardiovascular system. The opportunity to care for some of the sickest patients in the acute setting and to be able to follow them longitudinally over time has been rewarding.

I'm particularly interested in the single ventricle population. My research has focused on imaging biomarkers of long-term hepatic complications of the Fontan circulation, such as increasing liver stiffness and features of portal hypertension. As these patients are now surviving into adulthood, monitoring for long-term complications becomes imperative and is an exciting field for ongoing research. I'm also interested in pediatric heart failure and am investigating what donor factors may be contributing to transplant outcomes in these patients.

During my residency training, I was awarded the Research Innovation in Support of Excellence (RISE) award, a research grant jointly sponsored by the Cincinnati Children's Research Foundation and the Pediatric Residency Training Program.
