After early commitment to basic science during MD studies, Ph. Lysy undertook a PhD on the regenerative potential of stem cells for liver-based inborn errors of metabolism, under the supervision of Pr Etienne Sokal (UCL).

While finishing his formation in Pediatrics, he had the opportunity to spend two years as a postdoctoral fellow in the laboratory of Dr Susan Bonner-Weir at Joslin Diabetes Center, Harvard Medical School, to study the role of human pancreatic ductal cells as progenitors in the setting of beta-cell replacement strategies.

He learned his skills in pediatric endocrinology and diabetes at UCL and with Pr Lori Laffel and Pr Lynne Levitsky in Boston. Back in Brussels in 2011, Ph. Lysy joined the pediatric endocrinology unit of Cliniques Universitaires St. LUC (UCL) where he is currently involved in both clinical and basic research activities, these latter being focused on the finding of new technologies to maintain or restore the deficient beta-cell mass in type 1 diabetes.

Besides activities in international societies for pediatric endocrinology and diabetes (including ISPAD and ESPE), Ph. Lysy is co-chairing the research commission of the Belgian Society for Pediatric Endocrinology and Diabetes (BESPEED) and Association Belge des Pédiatres Diabétologues de langue Française (ABEPEDIAF), and is vice-president of a transversal research group inside UCL which focuses on obesity, metabolism and diabetes (OMEDIAB).
