I love building intelligent systems of people and computers, and working with multidisciplinary teams that make those systems possible. I draw from broad experience spanning entrepreneurship, product management, machine learning, data visualization, software engineering, human-computer interaction, experiment design, and economics.
Co-founder and CEO
Parsnip (“Duolingo for cooking”) applies the same feeling of “leveling up” in a video game to the real-life skill of cooking, so that anyone in the world can conveniently cook any cuisine at home. Our long term goal is to create a personalized AI companion for the home kitchen that teaches cooking and helps you figure out what’s for dinner.
Parsnip gained over 35k organic downloads, reached 4.9⭐ on the App Store, and was featured by Apple. Our users loved us and we probably reached product-market fit. We raised $450k from angel investors including the co-founders of Duolingo and a James Beard laureate, and learned a ton from making many mistakes.
Research Scientist & Product Manager (New York, NY)
Designed a machine learning platform for organizing 1TB+ of time series datasets & TensorFlow models, and automating model performance benchmarks on test data. Prototyped 2D and 3D interaction applications for demonstrating user interface control via machine learning from electromyography data.
Led a cross-team effort to build cloud infrastructure for training user-personalized machine learning models. Product manager for momentary event/signal detection from electromyography data, including R&D, data collection, accuracy metrics, user interface design, implementation, and product release.
Assistant Professor, tenure-track (Aarhus, Denmark)
Developed experiments and analyzed behavioral data on the ScienceAtHome citizen science platform.
Postdoctoral Researcher, Computational Social Science (New York, NY)
Ran the longest experiment of iterated prisoner’s dilemma ever conducted—lasting one month. Studied teamwork and collective problem solving in groups of various size. Developed a web framework for conducting real-time experiments of collective behavior using participants from the Internet.
