Premise
Take a system apart and put it back together until you understand exactly how it works. Then build the version that should exist.
My interests sit where hard physics meets computational theory. In my scientific research, that means biophysics: I built mathematical models of how DNA-based polymers can be used to perform experiments (aka 'lab on a molecule'), which fed into a drug-discovery platform now developing therapeutics. Outside scientific research, I build systems that move and learn, like a robotic arm I built and taught to manipulate objects via imitation learning.
I'm also interested in societal problem solving through serial entrepreneurship.

Building a dexterous robotic hand paired with an instrumented glove. The glove captures human hand motion so the robot can be trained directly on teleoperated demonstrations, giving it a path to develop the fine-grained manipulation that standard robot arms lack.
Three summers building a DNA-nanoswitch platform for therapeutic discovery. I derived polymer-physics and enzyme-kinetic models predicting nanoswitch conformational states, reaction rates, and binding equilibria, and used AlphaFold and Python to model nanobody-target interactions across autoimmune and viral pathways. I ran native PAGE gel-shift assays measuring binding enhancement of nanoswitch-discovered nanobodies on the PD-1/PD-L1 complex implicated in autoimmune disease. The platform has since spun into a company developing therapeutics, with candidates advancing toward clinical trials.

Venture Capital Intern
I evaluated spinning DNA-nanoswitch drug-discovery technology out into a new company, Merge Bio, assessing platform scalability, IP positioning, and commercialization strategy. I built the financial model end to end, a risk-adjusted revenue build, DCF, and sensitivity analyses spanning market sizing, pricing benchmarks, and probability-of-success adjustments across clinical phases. I also authored the scientific positioning on nanoswitch-based therapies for Type 1 Diabetes, covering PD-1/PD-L1 agonist mechanisms and the competitive landscape. The work fed into a $15M seed round.
