Research Interests:

My research focus is on algorithmic data mining on large and complex data. Specifically I am interested in the following topics:

  • searching and mining large and complex sequences: DNA, proteins, time series, event-interval sequences
  • searching and indexing non-metric spaces
  • mining electronic health records
  • influence and hierarchy detection in social networks
