Dr Sandipan Roy

Research interests:

  • Statistical analysis of networks and graphical models
  • High dimensional inference
  • Optimization Methods

Sandipan’s core research is at the intersection of statistics, machine learning and optimisation methods. His research is focused on modelling data with complex high dimensional network structure, providing methodology for estimating the corresponding structure. He uses tools from nonparametric statistics, graphical models and high dimensional inference. The emphasis is placed on developing new theoretical techniques and computational tools for network problems and applying the corresponding methodology in many fields, including biomedical and social science research, where network modelling and analysis plays an important role.
