I am currently a senior researcher at Qualcomm AI Research working on computer vision and deep learning. I completed my Ph.D. at the University of California, Santa Barbara, under the supervision of Prof. Yasamin Mostofi.
Research Interests:
- Computer vision and deep learning
- Robot decision optimization
- Human-robot collaboration
- Communication-aware robotics
- Novel RF sensing applications
Released Dataset for Perceptual Image Quality Assessment
The PieAPP dataset is now available publicly! See here for details.
Paper Repository on Human-Robot Collaboration
We have compiled a paper repository to provide a comprehensive overview of the state-of-the-art of different aspects of human-robot collaboration. Please check out the repository for more details.
Released Data and Code for Predicting Human Visual Performance:
We have made publicly available our data and code for predicting human visual performance using machine learning, which is developed in our RSS16 paper. For more details, please check out the data and code site.
