 I was born in Naini Tal, India, and educated at the University of Chicago, where I received
my Ph.D. in Mathematics (Differential Geometry and Topology) in 1987.
After teaching at Northwestern University for a year, I moved to the
University of Wisconsin,
Madison, as a Van Vleck Assistant Professor in
the Mathematics Department. In 1992 I became interested in the
applications of differential geometry to computer vision, and the
following year, I spent six months as an SERC
Visiting Fellow in the Program in Computer Vision at the Isaac Newton
Institute for Mathematical Sciences, University of Cambridge. In
1994, I became an Associate Scientist in the Mechanical Engineering
Department and later at the Center for Mathematical Sciences at the University
of Wisconsin. Subsequently, I moved to WHOI, where, since 2003, I have been a Research
Specialist in the Biology Department.
