I chair the laboratory of Tumor Immunology, Dept Medical Oncology, Erasmus MC-Cancer Institute (since 2000). The laboratory consists of 18 people, including PhD students and postdoctoral fellows, and research aims to understand how solid tumors evade immune control, and to explore therapeutic strategies to (re-) establish tumor-specific T cell responses according to 3 lines:
- Develop and test adoptive T cell therapy
- Understand and intervene with cross-talk between tumor cells and T cells
- Monitor patient T cell immunity
I participate in the research groups of the Division of Onco-immunology and Department of Medical Oncology.
Current research projects
- Treatment of melanoma and head-and-neck cancer patients with MAGE-C2-specific T cells
- Adoptive T cell therapy to treat common cancers: new roads to unique targets and pre-treatments
- Developing and testing combination immune therapies in preclinical models
- Immunophenotyping of tumors and blood of patients
Field(s) of expertise
- T cell biology and its shortcomings in tumors
- T cell treatments, in particular adoptive T cell treatment
- Molecular aspects of T cell receptors and gene-engineering of T cells
- Tools to monitor T cell immunity in tumors and blood of patients
Education and career
I have worked as a postdoctoral fellow for 3 years at DNAX Research Institute, Palo Alto, CA (currently part of Merck laboratories) in the field of immunology. I am a certified Immunologist (since 2005) and professor in T-cell immunity and adoptive therapy of tumors (since 2019).

I organise and lecture courses with a focus on T cell immunity and therapies (2 courses Molecular Medicine, since 2002; 1 course Infection and Immunity, since 2012; and 1 course Nanobiology, since 2018). I am faculty member of Post Graduate Schools (Molecular Medicine and Infection and Immunity, since 2012); departmental coordinator of research internships (curriculum medicine, since 2016); and departmental coordinator of annual research meetings for PhD students (since 2014). I supervise and guide individual research projects of PhDs (completed and ongoing co-promotorships: 14), clinical fellows and bachelor and master students (>40). In addition, I have been educational officer of an Innovative Training Network, an H2020 Marie Sklodowska Curie action (organizing workshops/courses for 12 international PhD students, 2010-2013).
Lastly, I participate in (inter)national thesis defence committees; and give international lectures per invitation as well as workshops for clinical specialists.
Scholarships, grants, and awards
Milestones of our laboratory:
The laboratory’s research resulted in phase I/II studies to assess the activity of gene-engineered T cells in advanced renal cell cancer, the first clinical study of its nature in Europe (completed); and advanced melanoma and head-and-neck carcinoma (scheduled for Q4 2019). Furthermore, translational research resulted in the selection of new targets and T cell receptors as well as strategies to sensitize tumors to T cell treatments (which are currently under development). In addition, immune profiling using multiplex technologies of large cohorts of patients with various tumors and treated with standard or experimental therapies revealed potentially new predictive immune markers.
