I am interested in Financial and Insurance Mathematics, mainly Stochastic control and its applications in Economics, Finance and Insurance. Some specific problems are
- Expected utility maximization under endogenous permanent market impacts
- Non-concave optimal investment with constraints.
- Transaction costs and the problem of approximate hedging
- Collective investment and risk sharing
- Optimal utility-based risk measures
