Computer Science from Northwestern University in 1983 and 1980,
respectively. He received his B.S. in Computer Science from University
of Arkansas at Little Rock in 1979.
At UAB, Dr. Bryant served as Associate Chair and undergraduate program
director. He was an ACM Distinguished Lecturer twice, received two
University-wide teaching awards, and was nominated for three Dean's
teaching awards at UAB. He advised 14 Ph.D. and 36 M.S. students,
published over 130 refereed articles in books, journals, and
conferences, and was PI or co-PI on research grants totaling over $9.3
Dr. Bryant's research interests are programming languages and
compiler design, component-based software engineering, and formal
methods in software engineering. In addition to his Chair duties, Dr.

Denis Conrady remembered
Denis Conrady died June 13, 2011 after a long illness. Dr. Conrady was
a faculty member in the Computer Science Department from 1974 to 1995.
Dr. Conrady taught classes in programming languages, compilers, and
After he retired from UNT, he moved to Indiana, but he came back in
2008 to visit the CSE Department in their new home at Discovery Park.
Don Retzlaff took pictures of his visit for this media gallery page.
Following Dr. Conrady's death, Don Retzlaff created this Memorial for
Denis Anthony Conrady and asked students to send their
remembrances. Many former students wrote to share their memories of
him and you can see that Dr. Conrady was a beloved faculty member of
the UNT Computer Science Department.
Dr. Tamara Schneider is new Lecturer
Dr. Tamara Schneider joins the CSE faculty as a Lecturer.
Dr. Schneider received her Ph.D. in Computer Science and Engineering at
the University of North Texas in December 2010. Following her
graduation, she was a post-doctoral research associate with the UNT
Computational Epidemiology Research Laboratory. Her research is in
analyzing and optimizing regional bio-emergency response plans,
disaster preparedness and synthetic cities.
Dr. Schneider is teaching two sections of CSCE 2100, Computing
Foundations I, and CSCE 4600/5640, Introduction to Operating
Systems/Operating System Design. More information about Dr. Schneider
is available at her website.
CSE Department celebrates 40th Anniversary
The Department of Computer Science and Engineering was founded as the
Department of Computing Sciences in 1971. When the department moved to
the newly formed College of Engineering in 2002, the name was changed
to what it is today. A history of all the faculty who have served in
the department is given on our website. We will
be celebrating this throughout the year with a number of special
Dr. Mikler gives keynote address at UNT Convocation
Dr. Armin Mikler gave the keynote address at the UNT New Student
Convocation on August 24, 2011. Freshmen and transfer students filled
the UNT Coliseum and were officially welcomed by Dr. Dale Tampke, Dean
of Undergraduate Students, and Dr. Warren Burggren, Provost and Vice
President for Academic Affairs. For pictures of the UNT Convocation,
please go to the CSE media gallery.
Dr. Mikler was selected to deliver this address since he received the 'Fessor Graham Award at the UNT Honors Day Convocation in Spring 2011. This
award is the highest honor given to only one faculty member each year
by the student body at UNT. This was the first time a faculty member
in the Department of Computer Science and Engineering has received
this prestigious award.
UNT CSE Summer Programs
UNT faculty members Robert Akl and David Keathly, along
with their camp staff, hosted four Robocamps and three Xbox Game
Development camps this summer. Funding was provided by the Texas

Dr. Krishna Kavi, Net-Centric IUCRC Director, received two new research
grants from NSF. In one case, he is part of team that was awarded
$975K for 3 years. The team includes faculty from UTD and SMU, in
addition to Dr. Kavi. UNT's share is $191K. In a separate project, Dr. Kavi
received $98K for 2 years from NSF. Both projects aim to explore how
applications behave when using Cloud computing. Specifically the teams
will develop tools to measure such properties as execution times,
vulnerability to security attacks, reliability and dependability of
applications when they are deployed on different Cloud platforms.
Dr. Kavi is continuing to work on a project funded by AMD. In this
project, Dr. Kavi and his students are exploring how to organize memory
using emerging technologies that permit stacking DRAM circuits on top
of processor cores.
Dr. Kavi and Dr. Robert Akl are working with Raytheon on developing
sensors to detect movement of fingers and forearm so that hand signals
used by soldiers can be translated into electronic signals and
communicated to other soldiers who are out of sight.
The NSF Net-Centric
Industry/University Cooperative Research Center will hold its
next semi-annual Industrial Advisory Board meeting at Arizona State
University in Tempe, AZ on October 18-19, 2011.

News from NanoSystem Design Laboratory (NSDL)
|(L-R) Karo Okobiah, Saraju Mohanty, Oleg Garitselov, Geng Zheng|
As strong demonstration of leadership research in low-power
electronics, NSDL director Dr. Saraju Mohanty has been
appointed to the editorial board of the Journal of Low Power
Electronics (JOLPE). JOLPE is a top-notch international journal that
publishes peer-reviewed papers focused in the areas of low-power VLSI
including AMS electronics and digital electronics.
As the first assignment he is working on to bring special issues under
the title "Power, Parasitics, and Process-Variation (P3) Awareness in
Mixed-Signal Design". In addition, Dr. Mohanty also guest edits a
special issue for the ACM Journal on Emerging Technologies in
Computing Systems (JETC) based on the selected papers from the IEEE-CS
technically co-sponsored International Symposium on Electronic-System
Design (ISED) 2010 in which he served as a program chair.
NSDL alumna, UNT's first woman Ph.D. with VLSI specialization, Dr.
Garima Thakral, has been employed with Aperia Solutions. NSDL
welcomes two new Ph.D. students. Geng Zheng joined NSDL to conduct his
Ph.D. research in Verilog-AMS behavioral modeling. Karo Okobiah, who
was awarded as the best Computer Engineering Masters student at the
last Honors Day celebration, joined for the Ph.D. in the area of
Kriging metamodeling for analog circuit. Oleg Garitselov's polynomial
and non-polynomial metamodeling research has already resulted in 3
highly-selective publications. In the last academic year, NSDL members
published 7 peer-reviewed journal papers and 9 highly-selective
conference papers. Most of these conferences follow the double-blind
review process with a typical 30% acceptance ratio.
NSDL has a Facebook page in an effort to popularize science and engineering with
the public. The research and education outcomes of the funded research
projects are presented for worldwide usage.
Dr. Paul Tarau presents 6 new research papers
During the Summer, Dr. Paul Tarau has presented the paper "Integrated
Symbol Table, Engine and Heap Memory Management in Multi-Engine
Prolog" at the International Symposium on Memory Management in San
Jose, CA, the paper "Coordination and Concurrency in Multi-Engine
Prolog" at the 6th International Federated Conferences on Distributed
Computing Techniques in Reykjavik, Iceland as well as a paper at the
International Conference on Logic Programming LPMAS'2011 workshop and
two papers at the CICLOPS'2011 workshop in Lexington, KY as part of
an NSF-supported project. The paper "Emulating Primality with Multiset
Representations of Natural Numbers" describing new results on
Computational Mathematics aspects of the same project were presented by
Dr. Tarau at ICTAC'2011
in Johannesburg, South Africa in early September.
Convergence Technology Center grant continues
UNT CSE has received an additional $24,905 as part of the three year
sub award from Collin College to participate in the Convergence
Technology Center. The CTC is an NSF funded center as part of the
Advanced Technology Education Program. David Keathly, Senior
Lecturer, is the UNT Principle Investigator and a Co-PI on the NSF
grant. The center works with other colleges around the country to help
establish programs and curriculum in Convergence Technology areas,
like networking, security, VOIP and mobile platforms.
The group is currently working on the next grant application to move
from a regional center to an NSF National Center. UNT's BAIT program
plays a large part in the efforts for this center as it provides a
transfer point for students completing Associates Degrees and
Certificates in Convergence Technology, as well as being a model
program for other 4 year schools in the partner college geographic
areas. Mr. Keathly has been a featured speaker at a number of
conferences representing both UNT CSE and the CTC, including the
Hi-Tech conference this summer.
