Engineer who studied health policy. Spent six years building software for healthcare at Firefly, studied the system at Harvard T.H. Chan School of Public Health, and heading next to Whoop as an Engineering Manager on Health AI. Curious about most things; enthusiastic about the rest.

001 · About

A short introduction.

The two-minute version. For the curious.

Between high school and college, I took a gap year to fundraise in the US and travel to Japan for tsunami relief. That early resilience training set the tone for everything after.

I studied CS and International Relations at BU because I couldn't pick. I thought a good overlap would be cyber security, but I didn't want a good day to be when nothing happens. I joined Firefly Health as their second engineer because I wanted software to do something that mattered. After six years building tech for clinicians, I came to Harvard T.H. Chan School of Public Health to study the other half of the problem: policy. Next stop: Whoop, as an Engineering Manager on Health AI.

Outside of that: I notarize things for friends, run the occasional half marathon, and keep birthday goals—some years one per age, some years a shorter list that fits the year. I am almost always up for a coffee.

Samsung Research America
Summer 2017
Samsung Research America software intern

A summer spent on a battery-research team, as the only software engineer in a room of chemists. Built a platform for visualizing experimental data and ran more digital experiments than I can count. Crash-coursed crystallography. Fell briefly in love with WebGL.

Boston University CS + International Relations

Magna Cum Laude with a double major because picking one felt unnecessary. Two years away from formal school beforehand gave me the clarity to study what I actually cared about, and a soft spot for women-in-tech advocacy.

2011 / 2012
Generation Peace Academy gap year

A year fundraising in the US and traveling to Japan for tsunami relief. Trudging through rejections on the street and finding gratitude in the mundane taught me resilience—and that bringing joy to those less fortunate is worth the effort.

Illinois Math & Science Academy high school

Three years at IMSA—my first time living away from home. Where I learned to love dance, got involved in leadership development, fell in love with philosophy, and found a community that encouraged me to embrace my nerdiness.

Projects, side quests, & oddities.

Some technical, some personal, all things I'm weirdly proud of.

Community Health Center Search Tool

Cambridge Half Marathon

I started setting goals tied to my age each birthday. That year: run a half, the whole thing. 9:23 pace. Taught me I can do most things if I dedicate the time.

Massachusetts Notary Public

Became a certified notary in the Commonwealth of Massachusetts because, well, why not. Hardest part: finding a practicing MA lawyer to vouch that I'm a good person. Available for notarizing your important documents.
