Research
My research is focused on enhancing our understanding of the mechanisms of placebo and nocebo effects (e.g., expectancies, learning processes such as conditioning and instructions, and physiological correlates) on pain and other physical symptoms. I hereby aim to contribute to improving clinical care and patients’ well-being through harnessing placebo effects and minimizing nocebo effects.
Background
I completed the Research Master Psychology and the Master Clinical Psychology at the University of Amsterdam (2011). I conducted my PhD research first at the Radboud university medical center and then at Leiden University under the supervision of Prof. dr. Andrea Evers, Prof. dr. Madelon Peters, and Dr. Antoinette van Laarhoven. I defended my PhD thesis ‘Harnessing placebo effects by targeting expectancies’ in February 2018. Currently, I work as a postdoctoral researcher and lecturer in Prof. Evers’ research group Psychoneurobiology of Health and Disease.
