Greetings from the CSE Chair

Chairman Barrett Bryant

Dear CSE Alumni and Friends,

Our UNT Department of Computer Science and Engineering celebrated its 40th anniversary on October 26, 2012. We are glad that so many of you came back to celebrate with us. It was a fun evening of connecting with old friends and meeting new friends. We are grateful to Nelson Cicchito, BS 1989, whose company Avatier Corp. sponsored this event. Alumni support is very important for the success of our CSE Department.

I want to share the news of many of our research groups in our CSE Department. We have a new NSF grant to support PhD students in our Center for Information and Computer Security. The Language and Information Technologies group is growing with the addition of Dr. Rodney Nielsen. Dr. Cornelia Caragea will also contribute to this group, and also the Center for Computational Epidemiology and Response Analysis. The Net-Centric Software and Systems Industry/University Cooperative Research Center is also growing and just had its semi-annual meeting. We are building our strength in software engineering with the addition of Dr. Renee Bryce. Please read below about all the activities in our department.

There are always opportunities for you, our alumni, to come back to campus. The week after our 40th Anniversary, UNT had its Homecoming weekend and the College of Engineering hosted a tent full of food with current CSE students making presentations. The Dean, Dr. Costas Tsatsoulis, and I were there to talk with alumni. It was good to see a few of you there. In Spring, you are invited to be a Professor for a Day and share your professional expertise with our students. Of course, you are welcome to visit us any time at Discovery Park!

Thanks for your support of our CSE Department!

In response to the success of the department's 40th anniversary celebration, university officials and alumni had the following comments:

The 40th anniversary event that the Department of Computer Science and Engineering held at Apogee Stadium in late October was not just a highly enjoyable experience, but appeared to me to be a turning point in the relations between the department and its alumni. The energy and enthusiasm was palpable, and several alumni indicated that they would come back every year to a event like this, not waiting for the next 40 years! The department is to be commended on this effort, as are the alumni who take obvious pride in their UNT education.

Warren Burggren, UNT Provost


It was a distinct pleasure to attend the celebration of the 40th anniversary of Computer Science and Engineering at UNT. Talking to the alumni it was clear how proud they were of their UNT degree, how their education had been instrumental to their professional successes, how connected they felt to their old department and alma mater, and how committed they were to give back. To all our alumni and to all our current students, I promise that we will continue to offer an outstanding undergraduate and graduate educational experience that can lead to life-long professional attainment, we will continue to add value to your degree, we will continue to make CSE and UNT ever better, and will strive to build stronger, long-lasting relations with everyone who calls himself or herself a Mean Green CSE graduate.

Costas Tsatsoulis, Dean and Professor, College of Engineering


It was my pleasure as Chair to see so many alumni and former faculty at our department's 40th anniversary celebration. There were graduates from all five decades of the department's history, including from the first undergraduate and Ph.D. Graduating classes, and the first faculty member, Dr. Tom Irby. Our department has grown a lot over the last 40 years and we will continue to advance and strive to be a department our alumni and former faculty can be increasingly proud of with each year.

Barrett Bryant, Professor and Chair, Computer Science Department



The 40th anniversary UNT Computer Science Celebration was a tremendous success. It brought together several decades of graduates and faculty from the 1970's all the way up to present. It was a chance for families and students and faculty to reconnect with people they have not seen for many years. New business relationships were forged and friendships created.

Before the evening's festivities, we received a personalized presentation from the Dean of the college and met with Chair of the department.

In addition to the great venue, food, drinks, and music, the evening offered incredible stories, shared experiences as well as a tour of the new Computer Science and Engineering Department. During the tour we were surprised to have a private demonstration of the latest computer science research from UNT. You were also surprised to learn graduates of UNT created the game "Call of Duty" and held important IT roles for major companies like PepsiCo.

UNT's Computer Science and Engineering Department has expanded a lot since I graduated but has been able to maintain the great staff while improving the quality of education they produce. Everyone should be proud as I am to graduate from this great university.

Nelson Cicchitto, BS 1989


It was a wonderful event! I had a lot of fun, and learned a lot about the new CSE Department. It felt great to be back on campus after so many years. Thank you!

Bin Li, MS 1996



I had a wonderful time at the 40th Anniversary Celebration! It was a great opportunity to meet with others in the industry, as well as catch up with past professors from the university! I was very glad I went, and I hope to attend any future events!

Stefan Zuefeldt, BS 2012



I graduated in 1998 and have so many fond memories of my time as a Computer Science student — from Ian Parberry's Games Programming class to Don Retzlaff's programming classes — all in the General Academic Building.

It was around 1996 when I took my first programming class with Don Retzlaff. The class was called Assembly Language and was very special to me because it marked the beginning of my rewarding and challenging profession in Computer Science. Eighteen years later I'm still in the Information Technology field. My career has been absolutely amazing and I owe it all to that first class I took with Don. He showed me the fun you can have with programming that eventually led to my decision to choose Computer Science as my major.

I'm grateful I was able to meet with Don and his lovely wife at the celebration event to thank him in person - 18 years later!

Danielle Gaither travels to Portugal for conference

Danielle in the courtyard at Belém Tower.

By Danielle Gaither, CSE PhD student

On the morning of September 9th, I arrived in Lisbon, Portugal for the purpose of attending the 3rd International Summer School on Domain Specific Modeling from September 10th-14th. Domain-specific modeling (DSM) is one approach to model-driven development (MDD). One goal of MDD is to have software models more tightly integrated into the code writing process than is currently the case in most instances. Many researchers believe that DSM is a better way to achieve this goal than using general purpose modeling languages such as UML (Unified Modeling Language).

Lisbon's excellent subway system took me from the airport almost all the way to my hostel door. In fact, nearly all my travel in Lisbon was by subway. I also visited Lisbon's Oceanarium, which contains marine life from all the world's oceans.

The summer school brought speakers from both academia and industry to talk about their work with various aspects of DSM. Topics included domain analysis, metamodeling, model transformations, model checking, model compositions, and methods for evaluating modeling solutions. We also had ample opportunities to work with some of the tools that the speakers discussed.

After the summer school ended, I traveled to Belém, which contains significant historical attractions. Belém Tower was built in the 16th century as part of a defense system for Lisbon and provides great views of the Tagus River, which runs through Lisbon. The nearby Hieronymite Monastery was also built in this time period and is a magnificent piece of architecture. One surprising attraction was the Berardo Museum, which contains art by many well-known modern and contemporary artists.

The summer school provided me with a lot of good information on DSM, as well as the opportunity to experience a wonderful city. I look forward to incorporating what I learned into my research.
