I studied computer vision and robotics at the University of Massachusetts at Amherst, and wrote a doctoral dissertation on multiscale representations of images. As a graduate student, I became interested earth’s sustainability and therefore joined the Earth, Atmospheric, and Planetary Sciences at MIT as a post-doc to research state estimation for dynamical systems. I continue at MIT as a research scientist (2004 - present), conducting research in earth systems and computational vision.

My enduring research interest is to design and use methods that can answer queries about the behavior of stochastic spatio-temporal processes. To do so, I broadly study estimation, control, decision and information theories. Currently, I focus on earth systems estimation, specifically to design algorithms that overcome the problems of nonlinearity, dimensionality and uncertainty that is characteristic of earth problems and a real barrier to effective predictability. You can read about specific research topics on this subject and others here.

Some of my research has made it out of academia, specifically to a company (WindRisk Tech) I co-founded in 2005. I served as a board member for Sustainable-step New England (2000-2002). I remain active in the environmental community, and present the (my) latest understanding of Climate and Sustainability to communities throughout New England.

I love to fly (airplanes), play the flute, and garden. I hail from New Delhi and I am married to Julie Marquardt from Connecticut.
