My name is Marjolein Verbiest. I recently started as a Research Fellow within the National Institute for Health Innovation and I will be working on three new HRC funded smoking cessation trials. I grew up in the Netherlands where I also obtained my Master’s degree in Health Psychology (2010) and PhD in Public Health (2014). My doctorate research focused on the implementation of smoking cessation care in general practice. I examined the effect of training health professionals in delivering evidence-based smoking cessation care and I looked at the impact of national tobacco control policies on GPs’ guideline adherence and on smoking prevalence. I look forward sharing my experience with you, being involved in the exciting projects within NIHI and CFAR, and being able to contribute to a smokefree Aotearoa 2025!
