Principal Applied Scientist at Meta
I started my career as a wet-lab biologist, before switching to computer sciences, earning my PhD in Artificial Intelligence from the University of Wisconsin - Madison. My early research spans biomedical informatics, statistical relational learning, and uplift modeling. I worked at Cisco and Google, as well as a biomedical informatics researcher, before joining Amazon in 2013 as the first recruit for Core ML, a central hub for ML excellence, whose mission was to disseminate ML throughout the company. I established and was the thought leader behind Amazon’s adaptive testing frameworks, researching, deploying and evangelizing bandits, with forays into reinforcement learning, causality, and diversity. I helped launch 27 business products across Amazon, Google, Cisco, and UW Health, which generated $2 billion incremental yearly revenue. I have published over 25 peer-reviewed papers in leading ML conferences and journals, and my work has been recognized with 4 paper awards.
