Hi, I'm Vishnu.

I'm a physician & software developer passionate about innovation at the intersection of medicine and technology.

About Me

I'm a practicing physician and software developer experienced in creating digital health solutions leveraging a variety of technology including machine learning, wearables and medical devices, and health data interoperability standards such as HL7 FHIR. I've done early work integrating conversational AI and wearable devices into clinical workflows and extracting insights from unstructured health data using machine learning.

Recently, I've built solutions for COVID-19 with international teams and I've been working on a framework for building digital health apps and making mobile health data useful for clinicians and researchers with CardinalKit at the Stanford Byers Center for Biodesign.

I started learning to code at a young age and have always been passionate about applications of technology to medicine. 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 and am certified by the American Board of Internal Medicine.

At Cornell, I co-founded the largest student media group and developed novel streaming technology. During my medical training, I built several digital health apps and co-founded a Techstars-backed startup developing software to extract insights from free-text clinical reports using natural language processing.

In 2020, at the start of the COVID-19 pandemic, I served as a mentor in the European Commission's #EUvsVirus program and built solutions with teams in the UK, Sweden and Germany. I co-founded Localing, an initiative to help small businesses in the UK survive the lockdown and subsequently was accepted to and completed the Accelerate Cambridge enterpreneurship training programme at the University of Cambridge Judge Business School.

Recently, in addition to practicing clinically, I have been working on CardinalKit, an open source platform for creating, managing, and scaling digital health apps at the Stanford Byers Center for Biodesign. I've also had the pleasure of mentoring engineering students at The George Washington University using machine learning to assist in the early detection of genetic disorders for the Children's National Hospital.
