Ali Çağatay Cırık

Ali received the B.S and M.S. degrees in telecommunications
and electronics engineering from Sabanci University,
Istanbul, Turkey, in 2007 and 2009, respectively. While he
is a member of CTT Group at Sabanci University, we completed
his M.S. thesis entitled “Iterative Low-Complexity Detection

of Dr. Mehmet Keskinoz. As a successful CTT member, we has
got scholarship from the Department of Electrical
engineering at University of California, Riverside(http://www.ee.ucr.edu/) to
pursue his Ph.D study. He is currently working towards the
Ph.D. degree on “Transceiver Designs for Full-Duplex MIMO
Radios with Self-Interference”, where he has developed
efficient algorithms for the optimization problems related
to full-duplex MIMO systems for such a promising technology
of future mobile networks. His industry experience includes
internships at Mitsubishi Electric Research Labs (http://www.merl.com),
Cambridge, MA, in 2012 and at Broadcom Corporation (http://www.broadcom.com/),

Mümin İmamoğlu

Mümin İmamoğlu was a member of CTT group durin 2006-2008 for
his M.S. thesis entitled “Distributed Detection Strategies
for Wireless Serial Sensor Networks”. In his thesis,
suboptimal fusion rules to the optimal fusion rule for
serial distributed detection were proposed . In particular,
the low and high SNR approximations of the optimal rule have
been derived. Then, the effects of node failure on the
serial distributed detection performance were investigated
and robust decision fusion rules under node failure have
been devised. Lastly, feedback strategies have been proposed
and appropriate decision fusion rules for the suggested
strategies have been derived. From 2009-2011, he worked in
Nortel Netaş, Istanbul/Turkey as a Design & Software
Engineer. Now, Mumin Imamoglu works as a researcher at the
Informatics and Information Security Center of the
Scientific and Technological Research Council of Turkey (TUBITAK),
Kocaeli, Turkey.
