Project: Understanding and Influencing Personal Health Behaviors

2013--present
Mobile and wearable devices enable us to study people's health behaviors in great details. In this project we aim to develop practical, energy-efficient, and user-friendly systems to automatically recognizing and influencing health behaviors.

Project: Mobile Analytics and Usability Testing

2010--2016, funded by NSF
We developed toolkits and algorithms for preditive analytics of mobile networking and app usage. In particular, currently there are few automatic mobile app usability testing systems and industry practice still heavily relies on manual efforts. We designed the first fine-grained interaction event logging system and a model-based event analytical system that can automatically identify usability problems for mobile apps.
