Dr SUN Lei is an Associate Professor in the Program of Cardiovascular and Metabolic Disorders, Duke-NUS Medical School. He received his B.S degree from Beijing University in 2001 and Ph.D in Biochemistry from Case Western University in 2008.  From 2008 to 2012, he underwent postdoctoral training in the lab of Harvey Lodish at the Whitehead Institute in Boston, MA. In 2012, he was awarded an NRF fellowship award in Singapore and joined the faculty at Duke-NUS. His research focuses on the RNA-regulatory network governing the development and function of major metabolic organs such as adipose and liver at various physiological and pathological conditions. The work from his lab has been published in scientific journals such as Cell Metabolism, Nature Metabolism, Nature communication, PLOS Biology and Diabetes.


Modern sedentary lifestyle and consumption of calorie-dense food are precipitating a rapid growing population of metabolic diseases such as obesity, type 2 diabetes and heart diseases. It is predicted, for the first time, that the current generation will have a shorter life-span than previous one. Understanding the molecular mechanisms underlying these metabolic diseases is urgently needed for us to prevent them or develop novel therapeutic strategies. Our studies are revealing a sophisticated RNA-regulatory network governing the development and function of major metabolic organs such as adipose and liver at various physiological and pathological conditions. We aim to determine the role of RNA regulatory network and how these RNA components crosstalk with the more well-understood protein network in the context of metabolic diseases. Our research topics encompass the regulation and function of non-coding RNAs such as microRNAs and lncRNAs, RNA processing such as splicing and editing, and RNA binding proteins.
