Financial and Actuarial Mathematics

The statistical processes underlying modern finance generate challenges to both commercial and academic communities. We seek to provide insight into these processes, accompanied by the development of innovative techniques and computational tools.

Current research interests include:

  • Optimal stopping of Levy processes,
  • Option pricing, credit risk models,
  • Portfolio optimization,
  • Measures of risk and deviation, advance data analysis,
  • Statistical methodologies and applications in actuarial science,
  • Financial applications of optimal stochastic controls,
  • Anticipating the critical transitions on markets.
