About me

I am a passionate researcher with a background in neurobiology and psychology. My research vision is guided by the principle that substance use should not be reduced to isolated mechanisms or deficit models; instead, individual behavior must be understood in its full cognitive, motivational, social, and cultural context. I aim to advance both fundamental science and societal understanding by integrating rigorous neurocognitive research with attention to real-world influences and accurate measurement, translating scientific insights into evidence-informed policy and public dialogue.

Research interests

Cannabis

Most of my research focuses on heavy cannabis use and cannabis use disorder. In recent projects we assessed:

  • Gender differences in symptom endorsement, mental health, cognitive performance, and brain activity
  • The role of cannabis attitudes – in the US and NL – in the association between cannabis use and brain activity
  • The role of attentional bias and craving in cannabis use, and whether cognitive control affects these associations
  • The moderating role of tobacco co-use in the effects of cannabis on a large range of cognitive functions
  • The effectiveness of a self-guided 2-week online intervention for cannabis use reduction

Other substances

My other projects have focused on other substance use, such as alcohol use, tobacco use, and NO use:

  • We developed a social attunement questionnaire – which is now available in Dutch, English, and Danish – and a task to assess the effects of individual tendencies to adapt to peers on alcohol use
  • We assessed the role of nicotine use in cognitive deficits observed in heavy cannabis users
  • We reviewed the existing literature on nitrous oxide use to assess whether nitrous oxide is an addictive substance according to DSM-5 criteria
  • We developed a gender sensitive questionnaire to assess barriers to treatment for alcohol use disorders

Measurement

In my research, I try to integrate different types of measurements and use a variety of analytical methods, including:

  • Assessing the associations between hair-derived cannabinoid concentrations and self-reported cannabis use
  • Using resting state and task-based fMRI to assess the neural underpinnings of cannabis use disorder
  • Developing experimental tasks and questionnaires to assess social influence of peers
  • Using network analyses to explore interactions between symptoms to look beyond diagnoses
  • Using experience sampling methods (ESM) to assess how daily fluctuations in mood affect substance use
