I will be joining the School of Computer
Science at the Georgia Institute of Technology as
an assistant professor in the fall of 2013. I am interested
in developing new technologies and cross-stack solutions to
improve the performance and energy efficiency of computer
systems for emerging applications. For more details, read
my research
statement. I am eagerly looking for students that
ambitiously want to make a difference!

``This paper is not just a doomsday predictor. It raises our
awareness of the problem through scientific quantification;
but it should also serve as a springboard for innovative
research, especially for computer architects. However, the
architect cannot hope to invent in a vacuum; the needed
innovations will surely come, but only by adopting a
holistic, cross-layer view of the full system—from devices,
through circuits, microarchitecture, system architecture,
and the software stack." Pardip Bose
``The last theme presents interesting perspective on
computer architecture trends by looking back and
looking forward. In ``What Is Happening to Power,
Performance, and Software?" Hadi Esmaeilzadeh et al.
analyze measured power and performance of a large
variety of processors and workloads to better
understand the combined effects and interactions of the
rise of parallel processors and managed programming
languages in the past decade. In ``Dark Silicon and the
End of Multicore Scaling," Hadi Esmaeilzadeh et al.
highlight a crucial impending problem where future
multicore chips will be power-limited to the point that
an increasing fraction of cores will have to be kept
powered off ("dark") at every new technology
generation." Co-Chairs of the selection committee
``With the availability of recent extensive and
insightful measurements done by Esmaeilzadeh et al.
[2011], we can look at the performance and energy
benefits of using SMT in single i7 core using a set of
multithreaded applications.'' Chapter three

``This treasure chest of data-recorded in large tables in the ACM Digital Library
in addition to this paper-allows the authors (and the rest of us) to ask and
answer many questions based on real hardware. This opportunity is a refreshing
change from research results based on simulation, which has dominated the
literature for the last decade." David Patterson
The Dark
Silicon paper presented in June 2011 at the
International Symposium on Computer Architecture (ISCA
'11) is profiled in
The New York Times:
``Even today, the most advanced
microprocessor chips have so many transistors that
it is impractical to supply power to all of them at
the same time. So some of the transistors are left
unpowered ... The phenomenon is known as dark
silicon. As early as next year, these advanced
chips will need 21 percent of their transistors to
go dark at any one time ... And in just three more
chip generations - a little more than a half-decade
- ... as many as half of them will have to be
turned off to avoid overheating."
