Research interests

A recurrent theme in my research is how to build statistical models to predict and explain task outcomes, which are essentially subjective opinions about a software failure. My models help me investigate how to aggregate conflicting opinions, decide if more opinions are necessary about the same item or different items, and who should we ask for further opinions.

While pursuing these research problems, I rely on a set of models and technology:

  • Theory: Decision Theory (e.g., voting, utility, prospect theory)
  • Probabilistic Models: Causal Inference, Bayesian Inference, Markov models and Bayesian Optimization
  • Empirical research: Quasi-experimental and Observational studies, Survival analysis, Analyses of covariance, and Sensitivity analysis
  • Application domains: Crowdsourcing, Software Debugging, Self-Adaptive Systems, and, more recently, Comments from Q&A sites or Newspapers
  • Tools/Languages: R, Python, Graph Database, Spark
