About

Biography

I am saying "Communication is sharing the past with the future." (Well, until spooky action at a distance has been successfully employed...)

She received M.Phil. degree from University of Liverpool, U.K., and Ph.D. degree from CCSR, University of Surrey, all in Electrical Engineering, in 2005 and 2009, respectively. Since 2009, she has been a Post-Doctoral Research Fellow at the Institute for Communication Systems (formerly the Centre for Communication Systems Research, CCSR), University of Surrey.

Research interests

Her main research interests include physical layer resource allocation, optimization, information theory and wireless communications.
