About Me

I'm a physician and software developer experienced in creating digital health applications leveraging a variety of technology including machine learning, wearables & IoT devices, and interoperability standards such as HL7 FHIR. I started coding at a young age and have always been passionate about innovation at the intersection of healthcare and technology.

I recieved my bachelors degree from Cornell University and my MD from the Albany Medical College. I completed a residency program in Internal Medicine from the Icahn School of Medicine at Mount Sinai. I'm currently a practicing, board-certified Internal Medicine physician.

I've created many applications including early work integrating conversational AI and wearables with electronic health record systems. I've worked with machine learning applied to clinical data and co-founded a startup as a medical student helping clinicians extract useful insights from free-text clinical documents.

During the COVID-19 pandemic, I built solutions with teams in the US, UK, Sweden and Germany. I was a mentor in the European Commission's #EUvsVirus program and co-founded Localing, an initiative to help small businesses in the UK struggling due to economic lockdown, launched with the support of the University of Cambridge Judge Business School's Accelerate incubator.

Recently, I have also been working on CardinalKit at Stanford University to make digital health apps quicker to build and mobile health data useful for research and clinical workflows.
