Dr. Lei Chen received the B.S. degree from the Department of Physics, Fudan University in 2003. He received the PhD degree at the Department of Physics, Florida State University (USA) in 2010. During PhD, he developed an on-chip SQUID measurement system at the high magnetic field (7 Tesla) and at the ultra-low temperature (5 mK), and studied the quantum tunneling effect of the single molecular magnets. From 2011 to 2013, he worked at the department of Chemistry and Chemical Biology as an post-doc researcher and developed a magnetic resonance force microscope for the study of the microscopic mechanism of the dynamic nuclear polarization. In 2013, he joined the SIMIT as the Associated Professor focusing on the research work of the nano-SQUIDs and the related applications.
