Hey, I'm Alyssa! I'm a security engineer at Stripe in San Francisco. I've helped build machine learning models for Radar, our product to stop payment fraud, infrastructure to help businesses handle chargebacks, and a number of account takeover protections for the Stripe Dashboard, including login and two-factor authentication flows.

Before joining Stripe, I did a PhD in biostatistics at Johns Hopkins with Jeff Leek. My research focused on computational biology, specifically developing statistical methods and software for finding differential gene expression with RNA sequencing data. A lot of my graduate work is publicly available, including papers, R packages, and talks.

I spent the summer after my 3rd year of grad school (2013) at the Recurse Center in New York City and loved it. Before grad school I studied math at St. Olaf College in Minnesota.

You can find me on Twitter, LinkedIn, and GitHub, or biking, hiking, skiing, painting, or doing improv around the Bay Area.
