Forschung

Forschung und Lehre spielen eine wichtige Rolle in der Medizin. Nur wer selber zu den aktuellsten Methoden geforscht hat, kann seinen Patienten kompetent Auskunft über Sinn und Unsinn neuer Therapien geben. Und der alte Grundsatz "docendi discimus", lehrend lernen wir, ist auch wohl bekannt - denn nur wer etwas wirklich verstanden hat, kann es auch anderen erklären und beibringen. 

Dr. Vavken ist aktiv in der Lehre an der Harvard Medical School und der Medizinischen Universität Graz tätig, sowohl im Gebiet der Orthopädie, als auch für Public Health und einen Health Care MBA und Hospital Management.
