About Me

I am a third-year Ph.D. student in the Computer Vision and Geometry Lab at ETH Zürich, working under the supervision of my advisor, Prof. Marc Pollefeys. My current research focuses on full autonomy for vision-guided micro aerial vehicles in both dynamic and unknown environments. Such research entails the development of algorithms for state estimation, visual SLAM, real-time 3D mapping, path planning, and exploration; all these algorithms are expected to run on-board the MAV.

I was involved in the recently concluded sFly project, and am currently involved in the V-Charge project.

I received my undergraduate degree in computer science with an additional major in economics from Carnegie Mellon University in 2006, and my Master's degree in computer science from Stanford University in 2007. I am currently sponsored by the DSO Postgraduate Scholarship.

Automatic Intrinsic and Extrinsic Calibration

I am working on algorithms enabling automatic intrinsic and extrinsic calibration. Accurate calibration is important for vision-guided robots. For more details on ongoing work, check out CamOdoCal.


3D Mapping, Path Planning, and Exploration in Dynamic Environments

I am developing algorithms that are able to run at high frequencies onboard a MAV with limited computational resources and enable the MAV to safely navigate cluttered indoor and urban environments with moving objects. The MAV builds a 3D occupancy grid that closely represents the geometrical structure of the environment, and plans a 3D path that keeps a minimum distance from obstacles and allows the MAV to reach its destination in the shortest time possible.

3D Reconstruction from RGBD Images

I am working on real-time techniques to build 3D structured and textured maps using data from RGBD cameras such as stereo rigs and the Kinect. Such maps can be used by robots for both path planning and visualization.
