I received my B.S. degree in Computer Engineering from the Middle East Technical University, Ankara, Turkey in 1994, and M.S. and Ph.D. degrees in Computer Science from the University of California Santa Barbara in 1997 and 2002, respectively. I joined the Computer Science Department at UT Dallas in September 2002 as an assistant professor and currently serves as a professor in the same department. I also serve as an associate department head for academic affairs and as the director of cybersecurity education programs in our department. Please see my CV for more details here.
My research interests include computer networks and protocols. More specifically, I have worked on network monitoring and Internet measurements; security of software-defined networks; and future Internet architecture design. In the past, I also worked on sampling of large scale complex networks; energy efficient broadcast in ad hoc networks; overlay networks and their use in network security; and group communication and IP multicast.
My current research efforts include use of ML based models in understanding and inferring topological structure of the Internet and BGP protocol; developing ML based intrusion detection systems for software-defined networks. I am also highly interested in the area of next generation Internet architecture design.
My recent work has been on Internet topology measurements area. Together with my PhD students, I worked on several practical problems in building representative Internet topology maps that are used to model and study the topological characteristics of the Internet.
My earlier work included using overlay networks to provide Denial-of-Service (DoS) resistant end-to-end communication service in the Internet; developing polynomial time algorithms for several energy efficient communication problems in ad-hoc wireless networks; and developing multicast debugging tools to facilitate multicast management and support multicast deployment efforts in the Internet. Some of our work was adapted and standardized by the IETF for implementation and deployment in the Internet (e.g., IETF RFC 6450).
So far, I graduated 6 PhD students four of whom now serve as tenured or tenure-track faculty member in academia.
I teach both undergraduate and graduate level courses on computer networks and network security. During the last several years, I taught Computer Networks Lab (undergrad), Advanced Computer Networks, and Network Security courses several times.
In early 2010s, I have written a computer networks laboratory book that I use for my Computer Network Lab course. This book includes eight lab exercises on GNS3 based virtual environment. The labs use Linux based virtual end systems and Cisco, Juniper, VyOS, or Quagga based virtual routers to build various network topologies to experiment with traditional networking protocols such as RIP, OSPF, BGP, and others. Students can deploy the virtual environment on their PCs/Laptops without incurring any additional equipment cost for the institution or for themselves.
Currently, I serve as the director of cyber security education programs at the CS department. I am also managing NSF sponsored Cybercorps: Scholarship for Service (SFS) Program for the department (awarded in 2010, 2014, and 2019). In this role, I am advising over a dozen scholarship students and mentoring them toward their successful degree completion and job search activities with Federal Government agencies.
