Miikka Vikkula, MD, PhD, is an internationally recognized leader in human and medical genetics, with more than 30 years of research at the intersection of molecular genetics, vascular biology, and rare diseases. He trained in molecular genetics at the University of Helsinki (MD–PhD), completed postdoctoral research at Harvard Medical School, and later earned a second PhD at UCLouvain. In 1997, he founded his independent research group at the de Duve Institute in Brussels, where he has been a Full Member since 2004 and Full Professor of Human Genetics at UCLouvain since 2013. Professor Vikkula is a pioneer in uncovering the genetic and molecular bases of vascular and lymphatic anomalies. His discoveries identified causes of numerous inherited and sporadic vascular disorders, defined key disease entities, and clarified central pathogenic pathways, including PI3K–AKT–mTOR and RAS–MAPK signaling. A defining feature of his work is its clinical translation: his team developed disease models and contributed to multiple clinical trials, including the phase III VASE trial of sirolimus and precision-medicine studies for arteriovenous malformations. He has authored over 250 research articles, cited more than 31,000 times (H-index 88), and received major international awards. He is a member of the Royal Academy of Medicine of Belgium and a Commander of the Order of Leopold.
