Research Interests
My prior work and training have focused on gaining a deep understanding of complex genetic eye diseases including Retinitis Pigmentosa (RP) and Stargardt disease. In particular, the additional time I have spent working with patients affected by these eye conditions has helped me to understand their unique visual deficits. The past few years, I have been working to develop and validate outcome measures for patients with RP. My goal is to not only develop better outcome measures for visually impaired patients with inherited retinal disease, but also to advance our understanding of how and when various aspects of functional endpoints are impacted with disease progression.
Clinical Interests
I am trained as a low vision specialist but also see patients for primary care and urgent eye care services. I am also interested in EMR/clinical informatics, the Merit-based Incentive Payment System (MIPS), and proper billing and coding compliance.
