Profile

Chrishan Ramachandra is Assistant Professor in the SingHealth Duke-NUS Cardiovascular Sciences Academic Clinical (CVS ACP) Programme, and Junior Principal Investigator at National Heart Research Institute Singapore (NHRIS). His research focus is on modelling human cardiac diseases with induced pluripotent stem cells (iPSCs), to discover personalised therapeutics, and new treatment targets for heart failure. He has modelled cardiac arrhythmias and cardiomyopathies, to elucidate mechanisms underlying disease pathophysiology, and has discovered potential targets for therapeutic intervention. He has been PI on grants, and authored over 40 papers in various cardiovascular disciplines, and serves on editorial boards. His scientific contributions have advanced the field in cardiomyocyte differentiation and maturation, cardiac disease modelling, and drug discovery. He has received several awards for his innovative research. He played a leading role in establishing the iPSC infrastructure at NHRIS, and now oversees the iPSC core, which conducts its own independent research, while extending support to other research groups.
