My research interests are in:

  • time series analysis (especially for non-stationary time series),
  • change-point and feature detection,
  • high-dimensional inference, regularisation and dimension reduction,
  • data-adaptive and multiscale methods in data science,
  • statistical learning,
  • networks.

I am also interested in the applications of statistics in economics, finance, the social sciences, astronomy and neuroscience.
