I work at Apple, doing research and development in the Geo Team.
Before joining Apple in 2012, I was in academia for ten years, first as as a student at ETH Zurich, then as a Ph.D. student (and briefly as an Assistant Professor) at the University of Tokyo, and later as a Postdoctoral Fellow at MIT.
My research expertise is graph and network algorithms, in particular shortest-path (query) algorithms.

This website is almost entirely about my academic research, with some links to teaching materials.
