Area of Study: Cardiac Electrophysiology
Dublin, OH


Research interests
I am interested in mechanisms of cardiac arrhythmias and how mechanistic understanding can guide novel imaging and treatment engineering.

Long term goals/aspirations

I would like to develop a practice in which I work with a team of scientists and biomedical engineers in the creation of novel devices and software to map cardiac arrhythmias. The dream would be to run the first in human tests of these diagnostic and treatment strategies.

Post MSTP Training dream job

After finishing med school, three years of internal medicine residency, three years of cardiology fellowship, two years of electrophysiology fellowship, and maybe some post-doc years thrown in there for fun, I hope to get hired as an electrophysiologist at a large academic center with an 80%/30% clinical to research split.


What you enjoy outside of school?

I enjoy Netflix movies, plein air painting, and Overwatch.

A talent you have always wanted:

Anything musical.

Favorite book:

The Count of Monte Cristo by Alexander Dumas

Favorite quote:

“You can never be overdressed or overeducated..” –Oscar Wilde

Can’t live without …

Can’t live without trees. Applied to be an astronaut for Mars One, but in reality I couldn’t leave all the beautiful greens and blues behind (also they rejected me).

If you weren’t in MSTP, what would you be doing now?

I would like to think in a different life I could pursue a career as a painter, but the lack of job security and need for public approval would stress me out too much.
