Pia Siljander

Pia R-M Siljander https://researchportal.helsinki.fi/en/persons/pia-siljander is a principal investigator of the EV group and an adjunct professor at the University of Helsinki. During her PhD at the Wihuri Research Institute, she focused on collagen receptor interplay in platelet activation, which started her ongoing work on platelet-derived extracellular vesicles (EVs) with her first EV paper in 1996 on microparticles. After her Postdoc at the University of Cambridge U.K., she returned to the University of Helsinki as a senior university lecturer at the Faculty of Biological and Environmental Sciences, Molecular and Integrative Biosciences research program until Feb 2026. As a principal investigator from 2011- (https://www2.helsinki.fi/en/researchgroups/extracellular-vesicles ), her continuing interest is to explore the biophysicochemical and functional versatility of platelet and cancer EVs and to develop methodologies for the EV field. The latter passion led to the founding of the world’s first EV core facility in 2016. Her research is driven both academically and through industry-collaboration. She has published over 50 EV-related publications, 31 of which have been cited > 100 times, has an H-index of 47 according to Google scholar, and was cited over 22627 times during the last 5 years.

Pia is a founding member and currently serves as the president of the Finnish Society of Extracellular Vesicles (www.fisev.fi).
