My Rresearch interests include: Telecommuncations Network, SPC Switching System, ATM technology (especailly Voice Over ATM), Wireless Communication, Frame Relay and etc.

Currently I am involved in the area of teletraffic aspects of wireless communication system, for both traffic model and mobility model.

I am a student member of IEEE Communications Sociaty.
