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

Current Projects:

1. Computer Vison

  • Multimedia Integration via Data-Driven Hamiltonian Monte Carlo (DDHMC)
  • Group Detection and Analysis in Video
  • Human Action Image/Hamiltonian Energy Signatures for Video Activity Recognition

2. Social Computing for Science Learning

  • Collaborative Argumentation
  • Threaded Discussion Metrics and Analysis
  • Question & Answer Online Communities

3. Data Science

  • Multimedia Analysis for Human Trafficking Detection
  • Machine Learning Methods for Data Analysis using Semantic Workflows
  • Reproducibility via Semantic Workflows
