He has been steering committee member of the group for the last two decades, he has published (from a total of over 300) around 50 peer reviewed manuscripts with various members of the group including many in high ranking journals such Lancet, Nature, JNCI and JCO. As PI or co-PI he received various grants for translational research with our group (BioMED1/2, DNA methylation, BASIS). He, together with several other members of our group, has been responsible for the biomarkers uPA/PAI-1 being listed in the current St Gallen guidelines as Level 1 prognostic markers for lymph-node negative breast cancer.
