Jefferson Y. "Jeff" Han (born 1975) is a computer scientist who worked for New York University's (NYU) Courant Institute of Mathematical Sciences until 2006. He is one of the main developers of " multi-touch sensing", which, unlike older touch-screen interfaces, is able to recognize multiple points of contact. Han also works on other projects in the fields of autonomous robot navigation,
