Research Focus

Our group is interested in the mechanisms of tumour clearance in response to targeted therapy with monoclonal antibodies. In particular, we aim to increase our understanding of the molecular pathways leading to non-apoptotic forms of cell death after ligation of surface antigens in lymphoma and leukaemia cells.

Research

Our group is interested in the mechanisms of tumour clearance in response to targeted therapy with monoclonal antibodies. In particular, we aim to increase our understanding of the molecular pathways leading to non-apoptotic forms of cell death after ligation of surface antigens in lymphoma and leukaemia cells.

At the systemic level, we are interested in how targeted therapy modulates the tumour niche via secretory and metabolic changes and what impact modulation of the stroma has on tumour growth and clearance.

From an applied cancer therapy perspective, we are interested in establishing the biological basis of synergy between various forms of targeted therapy and conventional radio- and chemotherapy.
