My name is Guang Huang. On July 20, 2015, I got my doctor degree in Dalian Institute of Chemical Physics, Chinese Academy of Sciences. My supervisor was professor Hanfa Zou. During my doctoral period, I have prepared polymer brushes grafted nanoparticles for glycopeptide enrichment by control polymerization and stationary phases for racemic compounds and basic compounds separation via click chemistry. After that, I got a postdoc position in the University of Alberta, supervised by professor Xing-Fang Li. Now, my research work focus on identification and quantification of disinfection byproducts (DBPs) of drinking water by HPLC-MS.
