Welcome!

Update: I successfully defended my thesis on Feb 29, 2008. I have now joined the Honda Research Institute in Cambridge, MA where I am working on computer vision for vehicular and robotics applications.

I am was a PhD student at the College of Computing where I work in the BORG Lab. My advisor is Frank Dellaert.

My research revolves around the application of Bayesian statistics to robotics, computer vision, and machine learning problems.

On the robotics side, my interests include mapping, localization, planning and spatial reasoning. I work mainly on geometric reconstruction and object recognition in vision. In the machine learning domain, my interests span hierarchical modeling, model selection, and linear dynamical systems. All these problems share the requirement of modeling data obtained from systems working in complex, real-world environments. In addition, the diversity of data sources, such as sensing devices on robots, each with its own error characteristics and limitations, adds to the challenge. My research is driven by the belief that theoretically sound algorithms based on probabilistic modeling are well-suited to the task of providing robust solutions to these problems.

Here is a list of projects I have been involved in (in reverse chronological order) -


Spherical harmonics based structure from motion without correspondences

Real-time Smoothing and Mapping (SAM)

Learning Applied to Ground Robotics (LAGR)
  Probabilistic Topological Mapping

Motion planning in high-dimensional spaces
Fast replanning in partially known environments
