Dr. Junping Geng received his B.E degree in plastic working of metals, M.S. degree in corrosion and protection of equipment, and Ph.D. degree in circuit and system from the Northwestern Polytechnic University, Xi’an, China, in 1996, 1999, and 2003, respectively.

From 2003 to 2005, he was a Postdoctoral Researcher with Shanghai Jiao Tong University, Shanghai, China. In April 2005, he joined the faculty of the Electronic Engineering Department, Shanghai Jiao Tong University. He was promoted to an associated professor in 2008, and he is now a doctoral supervisor.
From 2010 to 2011, he was a visiting scholar with the Institute Electrical and Computer Engineering, University of Arizona, AZ, USA.
He is a committee member of Antenna Society of Chinese Institute of Electronics. And he has been the Senior member of IEEE in 2017, and he also is the editor-in-chief of the Modern Antenna book series (Springer). Besides, he is among the editorial board of Nano Material, Journal of Antennas, and ever was among the editorial board of International Journal of Antenna and Propagation and International Journal of Aerospace Engineering. He has served as session chairs or member of Technology Program Committee (TPC) for more than 30 international conferences.
He is mainly engaged in the teaching and research work on the fields covering antenna, array and electromagnetic theory, wireless communications, and nano technology, etc. 
In 2015, he received the best paper award in IEEE MAPE 2015. In 2013, he was awarded the third rank of Shanghai Award for Natural Sciences. In 2010, he received the best paper award in IEEE i WAT2010. In 2008, he won the second prize of Chinese National Technology Innovation Awards as the third co-author. In 2007, he won the first prize of Technology Innovation Awards of the Ministry of Education as the fourth co-author. In 2009, he won the second Prize of ‘Hengshan Liangci’ Excellent Paper. He won the Shanghai Jiao Tong University excellent annual assessment in 2007, 2014, 2016, 2017, and 2018 respectively, and he also won the third prize for excellent teachers in 2008, excellent in the appointment period 2014-2016 in Shanghai Jiao Tong University too. He won the third prize of postdoctoral award fund in 2006.
