👨💻I’m a Director and Principal Data Scientist in Microsoft’s Core Search and AI group, where I contribute to the ChatGPT based New Bing. Prior to Microsoft I was a senior scientist/manager at Apple where I worked on teams that reinvented Apple Maps and launched the Apple Card. I’ve contributed to products used by hundreds of millions of people worldwide.
👨🏫I’ve held academic positions at Columbia, Brown, and the University of Colorado where I was a tenured professor of Geography and Information Science and the university’s inaugural Chief Data Officer. As an academic I worked at the intersection of Maps and Data Science. I wrote Urban Analytics and lots of articles, I received a distinguished scholar award from the American Association of Geographers, and the Brehny Prize for work in Urban Analytics and City Science.
📚Before becoming a professor and data scientist I briefly lived an insanely analog life as the sole propreitor of an antiquarian bookshop in Manhattan.
