PhD. Porsius, J.T.

Academic Background

Jarry Porsius studied Psychology at the University of Amsterdam with a specialisation in Social Psychology. After graduating in 2006 (cum laude), he worked as a junior researcher on the topic of implicit learning at Leiden University, and was a lecturer of applied psychology at the University of Applied Sciences Leiden.

In 2011 he started as a PhD candidate at the Department of Public and Occupational Health of the VU University Medical Center in Amsterdam. His PhD project was about the role of psychological mechanisms in symptom reports of nearby residents after a new high-voltage power line was installed. Most people are familiar with positive responses to placebo medication, but negative responses occur as well. In that case people report more health complaints after a placebo treatment, which is due to negative expectations of the treatment. In his PhD project he found support for these so called nocebo mechanisms to operate during the introduction of an uncertain environmental health risk, i.e. an overhead high-voltage power line. He received his PhD in Medicine in March 2016.

Currently he works as a postdoctoral researcher on the HiPP project. Working together with design professionals, industrial partners and orthopaedic surgeons, the main aim of this project is to optimise the patient experience journey of people undergoing total hip or knee replacement.
