Lydia Visser received a PhD from the University of Groningen, the Netherlands in 2000 on her thesis titled: ‘Antibodies against leucocyte common antigen (CD45)-applications in immunomodulation’. She subsequently held a post-doctoral position at the Robards Research Institute of the University of Western Ontario in London (Ontario, Canada) on a project on the mechanism of anti-CD45RB tolerance induction. She is currently working at the department of Pathology and Medical Biology of the University Medical center Groningen as a scientist. She is as a PI part of the SALL. Her research is mainly focussed on the immunology of lymphoma and consists of interactions of tumor cells with the micro environment and signalling pathways in Hodgkin lymphoma and non-Hodgkin lymphomas.
