Haochuan Mao

Graduate Student

Haochuan was born and grew up in Hangzhou, China. As he turned 18, unlike most of his high school classmates who continued staying in Hangzhou, he was tired of that city and went to Nanjing, where completed his undergraduate education in chemistry at Nanjing University in 2017. His research in college involves investigating the static spin state of some boron-centered and nitroxyl radicals under the supervision of Prof. Xinping Wang. Unsured about how working in a foreign country was like, he did a two-month research internship in the summer of 2015 at the Universty of Sydney working on Open Source Malaria with Prof. Matthew Todd and felt great. He likes spin, EPR and quantum mechanics, so he joined the Wasielewski group in 2017 and has been working to learn more about the dynamics of spin like teleportation and polarization.

Fangbai Xie

Graduate Student

Fangbai Xie was born and grew up in Wuhan, China. When he was in high school, he decided to study for Chemistry Olympiad and finally got a chance to participate in 46th International Chemistry Olympiad and won silver medal. That became the reason why he decided to studied for chemistry in Peking University in China from 2014. In Peking Univerity, he join in the Prof. Jian Pei’s research group and participated in the research about organic radicals and semiconductors. In the third summer of his undergraduate period, he did a summer research on supramolecular chemistry in Prof. Stoddart’s Group in Northwestern University and found that he is more interested in ESR and spintronics. That’s why he decided to choose Prof. Wasielewski’s group in 2018 for his graduate program. He would like to learn more about quantum computing and EPR/fsTA techniques to become a better researcher.
