Research group(s)

• Basic Oncology Research in Head and Neck Cancer
  Members:
  Gregor Heiduschka
  Sam Augustine Kandathil
  Victoria Stanek
• Hirtler Lab
  Head: Lena Hirtler
  Research Area: The members of this research group address a wide range of anatomical and clinical-morphological questions. Starting from classical anatomical and histological evaluations to clinical applications, e.g. minimally invasive surgery and imaging procedures, research questions are processed by the use of state-of-the-art techniques. Apart from stand-alone projects, the group is characterized by collaborations with a variety of partners to tackle currently relevant issues in clinical practice.
