In more than 30 years of clinical activity TWLS worked at three  academic university hospitals in two European countries, getting a broad overview  and being involved in multiple teaching activities in the fields of anaesthesiology  and intensive care medicine. His PhD thesis at the University Hospital in Düsseldorf,  Germany included numeral studies on cardiovascular physiology, and was  completed in 1999 after which he got his Habilitation (Associate Professor, Privat Dozent).

He was appointed as a full Professor of Clinical and Experimental  Anaesthesia at the University of Rostock, Germany in 2004, and as full Professor of  Anaesthesia and Cardiovascular Physiology at the University Medical Center in  Groningen, The Netherlands in 2010. At present, TWLS runs an active research  group on cardiovascular physiology and hemodynamic monitoring at this Dutch  University hospital.

His long-lasting interest in the fields of cardiovascular  anaesthesiology and physiology, particularly focussing on haemodynamic  monitoring including the microcirculation and tissue oxygenation, has led to more  than 100 peer reviewed publications in international scientific journals and  numerous lectures at national and international scientific meetings.

He is past Chair of the Section Cardiovascular Dynamics of the European Society of Intensive  Care Medicine. Furthermore, TWLS is Editor-in-Chief of the Journal of Clinical  Monitoring and Computing and Associate Editor of the journal Anesthesia &  Analgesia.
