“Science is not just knowledge. It is perhaps more about logical, critical, rigorous and innovative thinking. I wish Westlake University is not only extremely productive in research, but also plays a leading role in shaping the upward scientific spirit and training our future leaders in science. ”
Dr Hongjun SHI received his Bachelor of Biomedical Sciences degree in Human Genetics (1st class honors) from Victoria University of Wellington in 2006, and PhD in Pathology from University of Otago in 2012. After his PhD, he joined Victor Chang Cardiac Research Institute at Sydney as a post-doctoral scientist and conjoint lecturer at University of New South Wales. In 2017, he accepted the Assistant Professor position at Westlake University. His research interest is to understand the molecular mechanisms of cardiac development and congenital heart disease.

Congenital heart disease (CHD) is the most common form of birth defects accounting for ~1% of all new born. Currently only about 20-30% of CHD cases have identifiable genetic or environmental explanations. The majority of CHD arise from unknown causes, reflecting our poor understanding of the pathophysiology of this disease. At Victor Chang Cardiac Research Institute, Dr Shi analyzed the whole genome sequences of a number of CHD families, and identified several mutations in the NAD biosynthesis pathway that disrupt niacin metabolism and cause energy crisis in the developing embryos, resulting multiple congenital malformations including Hypoplastic Left Heart Syndrome-the most severe form of CHD. Dr Shi also found certain environmental insults, such as gestational hypoxia, anemia, and certain prescription drug uses, induce hypoxia and ER stress in the developing heart, resulting CHD. Importantly, these environmental factors may interact with mutations in the key cardiac regulatory genes such as those in FGF and NOTCH signaling pathways, significantly increasing both the severity and penetrance of the heart defects. At Westlake University, Dr Shi continues to investigate the molecular mechanism regulating the heart development and strive to uncover the novel etiology of CHD. His ultimate goal is to establish a more effective tool for the diagnosis and prevention of this disease.
