Research Interests

My research interests span across statistical theories and applications (mainly in epidemic processes such as earthquake and volcanic hazards), including

  • Point process theory
  • Stochastic models, especially in geophysics
  • Hidden Markov models and their applications
  • Survival analysis
  • Robust statistics
