Clinical training and expertise:

  • 1996-2002: Medical training at University Medical Center Groningen (MD)
  • 2002-2004: Clinical resident at department of emergency medicine, internal medicine and cardiology at Bethesda Hospital Hogeveen and Martini Hospital Groningen.
  • 2004-2007: Specialisation as a Family Medicine specialist at University Medical Center Groningen.
  • Since 2007 I work as a registered Family Medicine specialist, currently at an inner-city practice in Amsterdam, affiliated to Onze Lieve Vrouwe Gasthuis hospital in Amsterdam. Besides the full range of general practice and family medicine, I have a specific interest and expertise in cardiovascular medicine, more precisely thrombotic diseases.

Research activities and expertise:

  • 2007-2011: PhD training at the Julius Center for Health Sciences and Primary Care, University Medical Center Utrecht (thesis 2011: Strategies in suspected venous thrombo-embolism in primary care). Supervisors: professor Moons and professor Hoes.
  • Since 2011, I work as an assistant professor at the department of general practice of the Julius Center for Health Sciences and Primary Care, UMC Utrecht. The focus of my research is on thrombotic disease and management strategies for family doctors.
  • My goals are to develop and validate diagnostic and prognostic strategies in patients with (suspected) thrombotic disease, such as deep vein thrombosis, pulmonary embolism and atrial fibrillation. I work on approaches for early diagnosis and early warning signs for these diseases. Particularly pulmonary embolism too often remains unrecognized in primary care, potentially leading to missed and even fatal cases. It is my strong believe that family doctors play a pivotal role in early recognizing potential patients with thrombotic disease, and thus are in need for validated management tools for this difficult task. After the first phase of treatment is initiated, often in close collaboration with hospital specialists, family doctors again play a role in managing and recognizing the chronic clinical consequences, such as recurrent events, post-thrombotic syndrome, stroke and chronic thromboembolic pulmonary hypertension. This calls for prognostic strategies, which is also part of my research activities. Chronic prevention is often provided with oral anticoagulants, including vitamin K antagonists and direct oral anticoagulants. Balancing treatment initiation, compliance and risk of bleeding complications is often a task where family doctors need to work in close collaboration with hospital specialist to identify the optimal choice of anticoagulant management for their patients. Providing evidence for this task is also one of my keen interests, which is particularly difficult in elderly individuals given the complexity of multiple and conflicting treatment goals in them related to multi-morbidity.

Important awards and achievements:

  • 2013: Member of the Jacob Jongbloed Talent Society for talented young researchers at the UMC Utrecht in the field of cardiovascular disease.
  • 2015: Personal Veni award from the Netherlands Organisation for Scientific Research (NWO) on a project on personalizing diagnostic strategies in suspected pulmonary embolism in the elderly.
