Principle investigator

foto-24-04-16-06-34-55Martine Hoogman has a background in clinical neuropsychology (MSc, University of Amsterdam), and obtained her PhD by completing her thesis entitled ‘Imaging the effects of ADHD risk genes’ (Radboud University, Medical sciences, 2013).

She currently works as an assistant professor/ junior Principle Investigator (jPI) with a tenure track, at the department of Psychiatry and the department of Human Genetics, Radboud University Medical Center in Nijmegen. For almost 17 years she has been studying ADHD. She uses behavioral, cognition, brain and genetics studies to advance the field of ADHD.

She leads the largest international neuroimaging collaboration on ADHD, called ENIGMA-ADHD. Also, she leads a local study aimed at unraveling both the positive and deficient aspects of ADHD: IMPACT2-NL. In 2018, she was awarded the NWO Veni grant to study the link between creativity and ADHD. In 2020 she was awarded the ECNP rising star award, and in 2021 the KNAW early career award. Her team won the Dutch Open Science Award 2022 for the co-creation of a project on strengths in ADHD together with the Dutch organisation for people with ADHD.  

Her brother was diagnosed on and off with ADHD.  He, and all the other people with ADHD she met during her studies, are her inspiration to learn more about ADHD.
