About: I am a research scientist at the Columbia University, working with Prof. Shree Nayar. I did my PhD at the Robotics Institute, Carnegie Mellon University, where my advisor was Prof. Srinivasa Narasimhan.

 

Research Statement: My goal is to build computer vision systems that solve real-world problems. I believe that vision systems perform the best when both image acquisition and image interpretation (inference) modules work together. Following the two modules, my research has two main themes:

       Building high-capability computational cameras that capture maximal scene information in images even in challenging real-world scenarios. Designing such cameras requires using novel optics, electronics, sensing and programmable illumination hardware.

 

       Developing computational models for image inference using the physics and statistics of how light interacts with the world and the image formation process.
