RESUME

Dr. Qiu Longqing was born in Jiangxi province, in August, 1979. He received the B.S. degree and PhD. degree from the Department of Physics of Tongji University in July 2002 and March 2008, respectively. During August 2005 and July 2008, he studied in Forschungszentrum Juelich, Germany, as a sandwich PhD. Student researching ULF-NMR utilizing a HTS-SQUID. From September 2008 to the present, he worked in State Key Laboratory of Functional Materials for Informatics of SIMIT, CAS as an assist professor (2008.09 - 2010.12) and Associate Professor (2011.01 - present). He is currently research on “SQUID and its Applications", focus in “SQUID-based Ultra low field NMR/MRI” and “SQUID technology for geophysical exploration”. He is now working under several projects, such as National Science and Technology Major Project, International cooperation major project of CAS, as well as the Pre-research project of CAS, as a key researcher. He has been authored or co-authored more than 20 technical papers published in journals and conferences, and more than 10 granted and pending patents.
