Dr Christoph Kreitz Kestrel Institute 3260 Hillview Avenue Palo Alto CA 94304 U.S.A.

Dr. Christoph Kreitz's research focuses on the development of logicbased formal methods and their application to the design, verification, and optimization of reliable and secure software systems. He has built logicbased tools that automatically improve the performance of faulttolerant communication systems and guarantee that the improvements do not introduce errors. He also works on enhancing the automatic reasoning capabilities of tactical theorem provers such as Nuprl, Coq, and Isabelle and has developed machinecheckable proofs for the proof obligations in Specware's library.
He is interested in using his expertise in theorem proving and formal methods to help formally specify network protocols, develop code generation strategies, and develop strategies for the creation of machinecheckable proofs that verify the properties of the generated implementations.
