Contribution to Research Areas

Research Area G
My main focus are Backward Stochastic Differential Equations (BSDEs) as a powerful tool for solving stochastic control problems. E.g. we have appealed to BSDEs for solving the Skorokhod embedding problem, and we have derived time bounds up to which probability distributions can be embedded into a Brownian motion, possibly with drift.
Research Area H
A major focus of my research is market risk that cannot be perfectly hedged, but only cross hedged with highly correlated traded proxies. In particular, I have studied the effect of stochastic correlation and cointegration on hedge ratios and hedging error characteristics.
