Dr. Rob W.J. Collin
Dr. Collin is associate professor within the department of Genetics of the Radboud Academical Medical Center. His research group is working on the development of gene therapies for treatment of selected genetic subtypes of inherited retinal dystrophy. This disease causes blindness or severe visual impairment. The therapeutic strategies that are developed within Dr. Collin’s lab are aimed at correcting the genetic deficiencies causing the disease.

Prof. Hidde J. Haisma
Prof. Haisma earned his degree in Medical Biology at the University of Utrecht, The Netherlands, in 1983 and from 1982 till 1987 worked as scientist for the biotech company Centocor Inc. Malvern PA, USA (1985-1986), Dana Farber Cancer Institute, Brigham and Women’s Hospital Boston MA, USA (1986-1987), and as instructor at Harvard Medical School , Boston MA , USA (1986-1987). In 1987 he obtained his Ph.D. at the University of Utrecht, the Netherlands, with the thesis “Monoclonal antibodies and cancer”. From 1987-1997, he worked as scientist for the Section Experimental Therapy of the Department of Medical Oncology, University Hospital of Amsterdam, the Netherlands, and in 1997 he was appointed Assistant Professor/section leader of the Division of Gene Therapy within this department. In 2000, he left Amsterdam to become full professor at the University of Groningen, the Netherlands. Haisma’s research is devoted to the development of genetic medicines for therapeutic intervention of gene expression in patients. Prof. Haisma is member of the editorial board of several journals and has co-authored over 150 publications and holds several patents. He is former president and member of the board of the Dutch Society of Gene and Cell Therapy. In addition, he is member of the Gene and Cell Doping Expert Group of the World Anti-Doping Agency (WADA).

Prof. Enrico Mastrobattista
Prof. Mastrobattista obtained his PhD in Advanced Drug Delivery from Utrecht University in 2001 and spent over two years as a Marie Curie postdoctoral fellow at the MRC-Laboratory of Molecular Biology in Cambridge (UK). He currently leads a research group that develops biomimetic drug delivery systems for the targeted delivery of therapeutic proteins, peptides and nucleic acids. His main areas of expertise are drug delivery, pharmaceutical biotechnology and nanobiotechnology with a focus on the intracellular delivery of nucleic acids and genetic vaccines. Dr. Mastrobattista has published over 90 articles in scientific journals, contributed to several book chapters in pharmaceutical biotechnology and holds several patents to his name. In 2013 he was awarded the prestigious Galien research price, the Netherlands, for his research on drug delivery ( In 2018 he was appointed full professor in Pharmaceutical Biotechnology & Delivery at the department of pharmaceutical sciences, Utrecht University.

Dr. Jan Theys
Dr. Theys graduated as bio-engineer at the Catholic University of Leuven (KUL). Following the completion of his PhD at the Department of Immunology and Microbiology (Rega Institute, Leuven), he joined Maastricht University and became one of the co-founders of Maastro lab. He has been working as postdoctoral fellow, is staff member at Maastro and was appointed A/Professor at the Faculty of Health, Medicine and Life Sciences of the University of Maastricht. His main research interest centers around the importance of the tumor microenvironment with the goal to implement knowledge into innovative approaches that allow better treatment. Within that context, he leads an international consortium to generate a safe, antibiotic hypersensitive medical-grade armed non-pathogenic Clostridium vector that upon injection as spores, will germinate and thrive in necrotic tumour regions, providing cancer-specific colonisation, a totally natural exquisitely specific phenomenon. Upon concise development of the required technology, we stably “armed” Clostridium with a chemotherapy-activating gene (nitroreductase, NTR). We term this approach Clostridial-directed Enzyme Prodrug Therapy (CDEPT). We have obtained the critical proof-of-principle that the CDEPT paradigm can work and with all the technology required now in place, we aim to establish the clinical value of CDEPT.

Dr. Jeroen de Vrij
After receiving his PhD in 2012 (“Viral capsid modifications to improve oncolytic Adenoviruses”, LUMC, Leiden), Dr. de Vrij continued his research in the Dept. of Neurosurgery, Erasmus MC, with a major focus on the development of oncolytic viruses (OVs) for glioblastoma brain tumors. He has a major focus on the particular subject of using extracellular vesicles/exosomes as theragnostic system: (1) to improve OV therapy by packaging OVs in vesicles, (2) to analyze tumor-secreted vesicles in body fluids as a method for non-invasive monitoring of OV efficacy. Dr. de Vrij’s research ranges from vector construction towards clinical trial-related investigations. Novel OV therapies and diagnostics are tested in patient-derived xenograft mouse models as well as on patient-derived tumor cultures. The cultures rang from  classic 2D monolayers to highly complex 3D Avatar models, which strongly mimic the patient’s tumor microenvironment, including presence of immune cells, endothelial cells and extracellular matrix components.

Dr. Ingrid de Visser – Kamerling
Dr. Visser-Kamerling obtained her degree in Medical Biology at the University of Leiden, the Netherlands in 1998. From 1999 until 2004 she worked as a clinical scientist at the Centre for Human Drug Research (CHDR), Leiden the Netherlands. In 2003 she obtained her PhD degree with the thesis: “Clinical target validation for a non-peptide motilin receptor antagonist” at the University of  Leiden. In 2005 she became a registered clinical pharmacologist. From 2004 until 2007 she worked as policy coordinator at the research department of the Netherlands Heart Foundation. In 2007 CHDR appointed her as interim manager of education. From 2008 onward she holds a position of senior clinical scientist in different research fields, with main focus on gene therapy, viruses and vaccines.

Prof. Gerard Wagemaker
Prof. Wagemaker is emeritus professor of Hematology at Erasmus University Rotterdam, was trained in medicine, and in radiation, transplantation and stem cell biology.
