Andrew joined Etsy in 2014, and lives in London, making him their first data scientist outside the USA. Since then he has worked on a variety of challenges including localized recommendations, image similarity search and anomaly detection. Prior to Etsy he spent almost 15 years designing machine learning workflows, and building search and analytics services, in academia, startups and enterprises, and in an ever-growing list of research areas including biomedical informatics, computational linguistics, social media analytics, and educational gaming. These days he’s interested in probabilistic algorithms and data structures, online learning, deep learning, data visualization, and the convergence of search and recommender systems. He can count to over 1000 on his fingers but doesn’t know how to drive a car.
