I recently started my PhD in October, 2008 at Department of
Communication Systems (DCS), Lancaster
University. Currently, I am working with Prof.Bahram Honary on
MIMO-UWB systems for performance enhancements. Before, I completed my MS
at Department
of Computer Engineering, King Fahd University of Petroleum & Minerals
with specialization in wireless mobile ad hoc networks. Earlier, I received my
BS degree at Department of Electrical Engineering, UET (University of
Engineering & Technology) Lahore,
Pakistan. Here is my Curriculum Vitae.

The focus of the research is to find efficient channel modelling
for MIMO-UWB system. I have done ray tracing based channel modelling for
UWB under MIMO case. Currently, along with writing-up, I am working on rank
codes and interleaved rank code based STBC. My PhD is at its final stage now.
MS Thesis
I worked on Video transmission over MANETs (Mobile Ad hoc
Networks) as my MS thesis subject under the supervision of Dr.Tarek
Sheltami. The focus of the work was to
optimize the network performance in terms of the number of hops, delay and
power minimization issues when a MANET is subjected to video input. The combination
of mysteries of video compression / video traffic features and MANET are
inspiring to me and best match my interests. I successfully defended my thesis
on September 17, 2006. Here are my accepted proposal, MS Seminar on Proposal, and Final
Thesis Presentation.
