CWI researcher Kees Oosterlee has been appointed professor 'Hierarchical numerical methods' at the TU Delft on October 15, 2007. Oosterlee efficiently solves mathematical problems from industry with numerical methods. His focus is on engineering problems, such as problems in computational finance that require heavy and fast computation. One of the examples of his research is the development of numerical methods in credit portfolio loss modelling. This is related to the current subprime mortgage crisis at many banks: The risk of loss resulting from obligor's inability to meet its obligations has to be computed.
At CWI, Oosterlee works four days a week as a senior researcher in the Scientific Computing and Control Theory group (MAS2), in the field of numerical analysis and computational science and engineering. He is specialized in an efficient method - the multigrid method - which employs different problem scales or 'hierarchies' during the solution process. Oosterlee will concentrate his research at the TU Delft on the efficient combination of deterministic and stochastic solution methods.
