My name is Johannes-Simon Wenzler. I am Associate Professor in the Clinic for Restorative Dentistry, Periodontology and Preventive Dentistry at the University Hospital RWTH Aachen. You will get to know me at the latest within Module 5: Appearance, Adaption and Emergency Management and Module 8: Lasers in Periodontal Therapy with some of my very appreciated colleagues. I myself have been working in the clinical and scientific field for a few years, with a lot of passion, especially in the field of endodontology and periodontology, and I am focusing on the periodontal-endodontic interface. I am looking forward to a lively exchange and many new ideas in our master’s program.
