Dr Leo completed his PhD in June 2012 in the Discipline of Cell Biology & Anatomy, School of Medical Sciences at RMIT University, under the supervision of Professor Owen Woodman and Dr Joanne Hart. Prior to joining SUTD, Dr Leo is recruited to join Professor Laura Parry’s laboratory at The University of Melbourne in partnership with the pharmaceutical giant, Novartis AG to lead pre-clinical vascular studies to understand why a reproductive hormone, relaxin has beneficial effect in the phase III clinical trial (RELAX-AHF) for acute heart failure patients. In 2017, Dr Leo joined SUTD under MOE Singapore Teaching And Research Talent Scheme, where his research in natural product pharmacology aims to develop food waste derived nutraceutical products for health benefits. Furthermore, he also involves in multidisciplinary research projects in the area of 3D food printing, bioprinting of vascular mimetics, and serious games for healthcare and education.
