Yi-Tao Long received his Ph.D. in bioelectroanalytical chemistry from Nanjing University in 1998. After completing his two-year postdoctoral research at Heidelberg University, Dr. Long moved to Canada, and worked as a research scientist for 5 years at the University of Saskatchewan and the University of Alberta. Then he worked at the Department of Bioengineering, UC Berkeley as a senior research scientist from 2006 to 2007. Since 2008, he has been appointed as a Professor at the School of Chemistry and Molecular Engineering, East China University of Science and Technology (ECUST), China. Dr. Long received the Distinguished Young Scientist Fund from National Natural Science Foundation of China in 2011, and has been elected as a distinguished professor under the Changjiang Scholar Program of Ministry of Education of China since 2012. His research interests include nanospectroscopy, biointerfaces/biointerphases, spectroelectrochemistry, integrated biosensors, and nanopore single-molecule analysis. Chao Jing graduated with a B.S. degree from ECUST in 2010. She is currently pursuing her Ph.D. in analytical chemistry under the supervision of Prof. Yi-Tao Long. Her research interests include single-nanoparticle spectroelectrochemistry and biosensors.
