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.
