Especially his short fellowship in epilepsy surgery at the Cleveland Clinic in Cleveland, Ohio, with Professor Lueders and Professor Comair gave him the competence to establish a new program for Epilepsy Surgery at the Ludwig-Maximilians-University of Munich together with Professor Noachtar.

He established a Research Laboratory for Microsurgical Neuroanatomy in Munich and became speaker of the Section Microsurgery and Neuroanatomy of the German Society of Neurosurgery. His thesis for the Venia Legendi and Professorship at the Ludwig-Maximilians-University of Munich deals with lesions in and around the III. ventricle and the associated morphometrical, neuroanatomical, functional and neuropsychological investigations.
