Summary


ecturer at the University of Edinburgh Business School and Assistant Professor (Universitair Docent, UD) at Wageningen UR.

My research is focused on automated reasoning. I develop systems that aim to be robust and scalable in such a way as to enable computers to act intelligently in increasingly complex real world settings and in uncertain environments.

I have expertise in a variety of fields such as decision making under uncertainty, risk management, supply chain management, inventory control, production planning and scheduling, autonomic networking and cryptography. 

My research has appeared in international journals and conferences.
