Dr Sebastian Waszak is an Associate Adjunct Professor of Neurology at the University of California, San Francisco (UCSF) and the Head of the Computational Oncology Group at the Centre for Molecular Medicine Norway (NCMM). He obtained his PhD in Bioengineering/Biotechnology from the École Polytechnique Fédérale de Lausanne (2014) and completed his postdoctoral fellowship in childhood cancer genomics at the European Molecular Biology Laboratory (2019). His research focuses on understanding the genetic basis and cellular origin of childhood brain tumours and developing novel approaches for diagnosing and monitoring DIPG/DMGs. His research led to novel clinical practice guidelines for patients with embryonal tumours, protocol amendments for the international clinical trial SIOP PNET 5 MB, and the inclusion of novel entities in the WHO Classification of Central Nervous System Tumors (2021) and the upcoming WHO Classification of Genetic Tumour Syndromes.
