Curriculum Vitae: pdf
I am a postdoctoral
researcher at the University of Pennsylvania (UPenn). Prior
to UPenn, I was a PhD
candidate at York University (Toronto, Canada) under the
supervision of Prof. Richard
Wildes.
Research
Interests:
- How do we represent the visual dynamic world?
My research focus here is on understanding representational
aspects of video that make it possible to recover salient
information, with considerations made to being flexible to the
wide range of temporal image variation encountered in the
world.
- Perception for robotics: My interests in this
area include the representation of objects with optically
challenging appearance (e.g., semi-transparent, highly
specular or untextured) and the recovery of their pose with
respect to the camera.
