Bio

I am a Senior Researcher at Microsoft Mixed Reality. My research focuses on the intersection of Human Computer Interaction, Augmented Reality and Machine Intelligence. To tackle this broad problem space, I re-purpose off-the-shelf devices or build specialized hardware using my diverse skills in signal processing, machine learning, and RF engineering. I also design and conduct evaluation studies to quantify system performance in real-world scenarios. More specifically, I work on enabling human-level understanding of object behaviors using advanced statistical and machine learning algorithms. I also work on bringing the next generation of Augmented Reality experiences to IoT connected devices. I collaborate with experts across computer science, electrical engineering and design, which help me to identify great research and product opportunities and deliver broader impacts to the community.

I previously finished my PhD in Computer Science & Engineering, University of Washington advised by Dr. Shwetak Patel and Dr. Alanson Sample. with a focus on enabling sensing of user interaction with everyday objects.

Past Projects

Sensing and understanding user interactions with everyday objects can enable immersive Internet of Things (IoT) applications. In the following projects I explore several sensing and interaction techniques to blur the line between physical and digital experiences.

PaperID: A Technique for Drawing Functional Battery-Free Wireless Inter- faces on Paper.

IDSense: A Human-Object Interaction Detection System Based on Passive UHF RFID.

DeviceAR: Techniques for Device-oriented Augmented Reality Interactions

MoveVR: Enabling Multiform Force Feedback in Virtual Reality using Household Cleaning Robot

IDCam: Precise Item Identification for AR Enhanced Object Interactions

ID-Match: A hybrid computer vision and RFID system for recognizing individuals in groups.

FlexTouch: Enabling Large-Scale Interaction Sensing Beyond Touchscreens Using Flexible and Conductive Materials

ShopSight: A Retail Analytics Platform Tracking Consumer Behaviors in Physical Stores.
