Dr. Liu Xiaogang has a multidisciplinary education, work, and research background. He studied in electrical and electronic engineering (2002—2006, B.Eng.), materials science and engineering (2008—2009, M.Sc./M.Eng.) and physical chemistry (2010—2014, PhD). He also worked in the industry as a product engineer (2006—2008, semiconductor), a research engineer (2010, optics), and a research associate (2013, solar cells). He began his independent research with a SMART Scholar Fellowship (2014—2016), and joined SUTD as an Assistant Professor in 2017.

Dr. Liu Xiaogang’s current research is to study the fundamental structure-property relationships of organic fluorescent dyes and sensors, which can be used in a diverse range of applications, such as fluorescence imaging, solar cells, and dye lasers. Based on such knowledge, he is developing novel fluorophores and sensors with enhanced performance.

His long-term research vision is to set up a complete set of molecular design rules, such that one gains the ultimate ability to molecular engineer “dial-up” properties to suit a given application. He hopes to shift the chemistry of fluorophores from trial-and-error to molecular engineering.

Dr. Liu Xiaogang and his co-workers’ research has been highlighted by ACS Noteworthy Chemistry of American Chemical Society (2014), and voted as the #4 of top 10 breakthroughs in Physics for 2010 by Institute of Physics.
