Let’s build a brighter future.

I study the brain and business at Emory, and I’m building toward a neurotech startup. The goal is simple: make products that genuinely help people, and show the next generation what happens when you dream big and do the work.

Right now that means two things at once: the Jiang Lab at Emory, where I study ALS, and building products people use. The startup I’m working toward lives where those two meet.

My story

My first pitch was a patch of snow. Every Christmas in Seattle, my two older brothers and I kicked the clumps aside and made our own turf. Opponents called me Huggy — I clung to attackers and never let go. The dream was simple: “Kim” on the back of a Barcelona shirt.

At fourteen, things got real. I signed with a Spanish academy and moved to Valencia with my mom. My optimistic expectations were shattered by reality: the language was indecipherable, the cultural barriers took a toll, and the soccer was at a level I had never played before. But with my eyes set on the goal, I carried a Spanish vocabulary notebook everywhere, woke up at 6 a.m. to train alone and hit the gym, and spent long nights studying how the professionals played. By year four I was fluent in Spanish and playing against La Liga youth academies.

Everything seemed to be going perfectly, and I began to see the light at the end of the tunnel.

Then, during a match, a defender slid in. My knee twisted, and the thing I’d built my whole identity on was gone in an afternoon.

I hit rock bottom. My grades were a disaster, and I no longer had soccer to lean on. For months I was depressed, hopeless, and without a sense of purpose.

When a flower dies, it leaves room for others to bloom.

Without soccer, a new interest emerged. Selling fidget spinners in elementary school had already introduced me to entrepreneurship, and with more free time my world filled with Shark Tank and business documentaries. That spark became a double major at Emory, big aspirations in the business world, and a future I can’t wait to run into.

Experience

  1. Undergraduate Researcher

    sept 2026–current
    Jiang Laboratory · Emory Department of Cell Biology

    Research on the mechanisms of neurodegeneration — ALS and frontotemporal dementia — in a lab working across cellular and animal models toward therapies for both.

    Current project. Testing whether the endogenous retrovirus HERV-K drives the mislocalization of TDP-43 — the protein that leaves the nucleus in almost every ALS case — in HEK293T cells: PEI transfection of HERV-K and HERV-K Env constructs against an H2B-mCherry control, fixation at 48 and 72 hours, then immunostaining for TDP-43 and mCherry. Alongside it, routine culture of NSC-34 motor-neuron-like cells carrying human SOD1 G93A, the lab's ALS model.

    In plain terms. ALS kills the neurons that move your body. TDP-43 is the protein that goes wrong in almost every case. We’re testing whether an ancient virus written into our own DNA is one of the things that sets it off.

  2. Founder & Developer

What lasts

“What good is it for someone to gain the whole world, yet forfeit their soul?”
— mark 8:36

One day, everything I build will cease to exist — this website included. So I won't chase things that fade, or treasure metals that rust. Nothing I achieve can give me true peace or joy. That comes from Jesus Christ alone.
