Professor LIU YouCheng is a pioneer of free radical chem-istry in China. He was elected as a Member of the Chinese Academy of Sciences in 1980 and as a Fellow of the Royal Society of Chemistry in 2008. Professor Liu set up the first laboratory of free radical chemistry in China at Lanzhou University, Lanzhou, Gansu Province and has made out-standing contributions to many aspects of free radical chemistry. Therefore, he is generally known as the founder of free radical chemistry in China. I was fortunate enough to be a student of Professor Liu for my MS and PhD qualifica-tions and had the privilege of being educated and guided by him. I have been deeply impressed and influenced by his dedication and enthusiasm to science, his rigorous attitude towards scientific research, his hard-working and modest personality, and the great care and attention he pays to his students and colleagues.
