Professor Walter Stummer, M.D., Ph.D.
Chairman of Neurosurgery, Munster University Hospital
Dr. Stummer is a world leader in the introduction and implementation of advanced fluorescence-based diagnostic methods in operation microscopy and microneurosurgery.
He is the neurosurgeon who introduced the use of 5-ALA in the resection of high-grade gliomas, and has published extensively on the 5-ALA method, from applied laboratory research to the operation room.
Dr. Georg Widhalm
Assistant Professor, Department of Neurosurgery
Medical University - Vienna, Austria
Dr. Widhalm is a clinical scientist/surgeon who is a leader in fluorescent-guided surgery focusing upon biomarkers and disease detection. His dissertation work was pivotal in demonstrating the use of Gleolan for low grade Gliomas that are hiding anaplastic malignancies in 48% of the “nonmalignant" patients. This game changing observation affords the use of Gleolan in all patients in his hospital to assure maximal tumor removal as standard of care. His insight and expertise underlies his translational approach to novel tumor applications.
