Kang Yan is an associate professor at the college of aerospace engineering, Nanjing University of Aeronautics and Astronautics, Nanjing, China.

He received B.E. and M.E. degrees in Materials Science and Engineering from Nanjing Tech University and Shanghai University in 2000 and 2006, respectively. From April 2006 to March 2009, he studied at Department of Intelligent Systems Design Engineering of Toyama Prefectural University, Toyama, Japan, and received his Ph.D. in Intelligent Systems Design Engineering in 2009. From October 2009 to October 2016, he was a postdoctoral researcher in Nanoelectronics Research Institute (2009-2012) and Department of Energy and Environment (2013-2016) of National Institute of Advanced Industrial Science and Technology (AIST), Tsukuba, Japan. From April 2012 to September 2013, he worked as a postdoctoral researcher in Advanced Materials Processing Unit of National Institute for Materials Science (NIMS), Tsukuba, Japan. He has authored/coauthored more than 30 papers in refereed journals.

In early years, he focused on the research of fabrication technique of piezoelectric/ferroelectric ceramics and films. He has firstly reported a high-performance BaTiO3-based ceramics using a novel two-step sintering technique in Toyama Prefectural University, and also studied the fabrication of ferroelectric gate field effect transistor (Fe-FET) in AIST. Recent years, he began to study the morphotropic phase boundary (MPB) of piezoelectric/ferroelectric ceramics and discovered a crucial structural difference between the high- and low-performance piezoelectric MPBs. His current research interests are in the field of piezoelectric/ferroelectric materials and related applications, especially for designing high-performance MPBs in lead-free piezoelectric ceramics.
