Research Interests:

My research uses fundamental ideas from machine learning and computational science to study crowds in video and online communities. I develop theoretical and applied models and algorithms to examine problems in:

Computer Vision: physics-based methods for group analysis in video
Data Science: bioinformatics and semantic workflows for multimedia analysis
Social Computing: virtual communities and science learning group collaboration
