Biography:
Mohd Adzir Mahdi received his B.Eng. degree from the Universiti Kebangsaan Malaysia, and M.Sc. and Ph.D. degrees from the Universiti Malaya in 1996, 1999 and 2002 respectively. He joined the Department of Computer and Communication Systems Engineering, Faculty of Engineering, Universiti Putra Malaysia on January 21, 2003.

He is now an associate professor at the Universiti Putra Malaysia. Prior to the current position, he worked for a start-up company; Pine Photonics Communications Inc. in Fremont, CA, USA during the period of economic boom there. He then opted for another start-up company; IOA Corporation in Sunnyvale, CA to further sharpens his skills and widens experiences. It was during his stint at both companies that he came up with 2 commercial designs, 1 alpha prototype and 4 engineering prototypes that all related to optical amplification technologies. Adzir served as a research officer at the Photonics Laboratory, Research and Development Division, Telekom Malaysia Berhad.


Since 1996, he has been involved in photonics research specializing in optical amplifiers and lasers. His notable research contributions in this area have earned him international recognition awards; IEEE LEOS Graduate-Student Fellowship, Australia-Malaysia Institute Research Fellowship and TWAS Young Affiliate Fellow. He has published more than 240 scientific papers in journals and conference proceedings. Together with his research team, he has supervised 6 PhD, 19 MS students, and currently supervising more than 15 post-graduate students.

Adzir is a senior member of the Institute of Electrical and Electronics Engineers (IEEE), a member of the Optical Society of America and International Association of Engineers. His research interest includes optical fiber amplifiers and lasers, optical fiber communications and nonlinear optics.
