Wouter received his postdoctoral training in the lab of Ton Schumacher at the Netherlands Cancer Institute, where he focused on dissecting the interactions between T cells and tumors. He has a particular interest in developing new technologies that enable the large-scale mapping of T cell specificities. Now, he aims to apply these technologies to interrogate the tumor-reactivity landscape of T cells, as well as to develop the next generation of TCR gene therapies.
