Assistant Professor

About Me

I am a clinical epidemiologist and assistant professor of oncology care at the University of Twente. I also have an external positition at the Netherlands Comprehensive Cancer Organisation (IKNL). I obtained my PhD in 2018 at the University of Twente. My thesis was entitled: “Local management of early breast cancer and clinical risk prediction of survival”. In this thesis I mainly focused on 1) the evaluation of breast-conserving therapy and mastectomy in the daily breast cancer population, in which I worked with several methodologies suitable for observational research, and 2) development and validation of prediction models for use in daily clinical practice.

My current research activities include research on long-term outcomes following a variety of treatments for breast cancer. I am involved in the registration of pathologically confirmed recurrences in the Netherlands Cancer Registry (NCR), which is hosted by IKNL. I am part of the NABOR project team working on a by ZonMW subsidised research on personalised breast cancer follow-up. Here I am responsible for the development/update of the INFLUENCE 3.0 prediction tool that estimates the risk of locoregional recurrence and second primary breast cancer, for which I use the data from IKNL.

I teach on research methodology and quality of care in several modules within the BMT/BME and GZW/HS bachelor and master programmes. Besides, I am co-developer of a new learning line in the BMT bachelor on methodology and statistics.

Furthermore, I am a board member of the Netherlands Epidemiology Society (VvE) in which I focus on advanced epidemiological methods: how do we make sure epidemiologists within and outside of academia know of these methodologies and how can we spread our knowledge. In addition, I am member and coordinator of the national breast cancer working groups (NABON-BOOG) scientific evaluation committee of NCR data requests.
