Though after the PhD I am shifting my research focus to Machine Learning (mostly Deep Learning), the majority of my research so far has centred around optimal decision making under uncertainty. In more detail, I have engaged in the study of

  • sequential testing/estimation and quickest change-point detection problems in Bayesian Statistics,
  • optimal sequential decisions (typically, trading strategies),
  • stochastic differential equations and filtering techniques.
