Biography

Professor Alex Ka Nang LEUNG received the B.Eng., M.Phil., and Ph.D. degrees, all in Electrical and Electronic Engineering (now the department is renamed to Department of Electronic and Computer Engineering), from the Hong Kong University of Science and Technology (HKUST).  He stayed at HKUST immediately after he got the Ph.D degree in 2002 and became a Visiting Assistant Professor. After his 3-year service to HKUST, he joined Department of Electronic Engineering of the Chinese University of Hong Kong (CUHK) in 2005. He is currently an Associate Professor.

He is a senior member of IEEE, and he is the chairman of IEEE (Hong Kong) Electron Device/Solid-State Circuit Joint Chapter. He serves in the editorial board of Active and Passive Electronic Components, Hindawi Publishing Corporation, and he serves as paper reviewer in numerous IEEE & IET journals and international conferences. Moreover, Professor LEUNG involves actively in the organization of several IEEE international conferences.

Professor LEUNG is the recipient of the Young Scientist Award of the Hong Kong Institution of Science in 2003. He received the Departmental Exemplary Teaching Awards in 2007-2008, 2009-2010 and 2010-2011, and he received the Faculty Exemplary Teaching Awards in 2007-2008.
