- Data Science at Amazon Robotics. I am currently a data scientist at Amazon Robotics. I'm working on improving robotic fulfillment and transportation buildings, all toward the goal of optimizing a logistics network that handles billions of items each year.
- LP. I am a limited partner in funds focused on software (typically SaaS) and artificial intelligence. For inquiries here, my email address is < first-name >.< last-name >[at] gmail [dot] com.
- Instagram content moderation. As a data scientist at Instagram, I worked on content moderation, including the measurement and automated removal of objectionable content that violates FB's community standards. The problems in this space lie at the intersection of free speech and creating safe online communities.
- Health care. Before that, I was a data scientist for a hospital working on population health. Our goal was to manage patient care to prevent them becoming sicker and incurring more expensive and intensive care. I built predictive models to forecast all-cause inpatient readmission risk and other events to reduce unnecessary patient care.

My academic research
sits at the intersection of the social sciences, physics, and computer science. I am interested in how individual actions give rise to collective phenomena in large populations. Applications include the complex interplay of social forces that produce collective intelligence
, group problem-solving
, consensus formation
, and social norms
in human social systems.
To understand the dynamics of complex systems, I rely on agent-based models to gain theoretical traction on a social behavior. Then, I test these ideas using online experiments to see if these theories hold true.

I have an occasional blog
where I write about research projects and interesting things like
causal discovery (or how you can learn the causal structure of a system)
, and hopefully more things!
