&about_img1=images/research01.jpg& &about_readmore_title1=The Networking Systems Lab &about_readmore_txt1=The vision we have for the Networking Systems Lab (NSL) is to become a leading networking research hub in the region. The lab members and collaborators form a formidable team conducting research at CMU-Qatar in numerous areas of Computer Networks. These areas include Delay and Disruption Tolerant Networks (DTNs), Multi-hop wireless mesh networks, and the intersection between mobile and social networking. The NSL, directed by Dr. Harras, was founded at the end of 2009 at Carnegie Mellon University in Qatar (CMU-Q). Since CMU-Q does not currently have graduate programs in place, the lab follows an industry model to a large degree, where members include Postdoctoral Researchers, Full-time Research Engineers, and Graduate students via internships or NSL collaborators. To learn more about the NSL projects, members, and collaborators, please visit our webpage. & ///////////// teaching //////////// &services_txt1=Courses &services_txt2=At Carnegie Mellon, I am mainly involved in teaching the Systems track of our curriculum next to a few other courses.

Prior to joining CMU, I taught a couple of courses at University of California in Santa Barbara (UCSB) including introductory programming, C, and Unix. & &services_txt3=Philosophy &services_txt4=Personal Teaching Philosophy
The following Chinese proverb largely reflects what my teaching experience and philosophy revolves around: "Tell me and I forget. Show me and I remember. Involve me and I understand". While really difficult at times, I try my best to incorporate this in my classes and style. &services_txt5=READ MORE &services_txt6=Awards &services_txt7=%bb 2010: The "Outstanding Commitment to Undergraduate Teaching" based on student voting at Carnegie Mellon University in Qatar. %bb 2006: The "Outstanding Educator" based on student nominations while working as an Instructor for two courses at the College of Engineering at UCSB. %bb 2002-2005: The graduate level "Outstanding Teaching Assistant" award three times during graduate school while at Computer Science department at UCSB. &services_img1=images/teaching01.jpg& &services_readmore_title1=Teaching Philosophy &services_readmore_txt1=The ultimate goal of a good education is learning how to learn. At the end of the day, this skill is the major asset that students will carry with them as they adapt to the constant changes they will face in their lives. This asset becomes more crucial to those studying computer science and engineering, due to the speed at which these fields are developing and changing. In order to supply students with the ability of learning how to learn, it is not what is poured into them, but rather what is planted, that really counts. The objective of teachers, therefore, does not only involve explaining subject matter to students, but should also include a number of other fundamental objectives. First, teachers must show students how the material fits into the big picture. Teachers should act as guides for their students, directing them toward finding answers and solving problems by providing them with the tools needed to do so. Furthermore, teachers should be approachable and should make students feel comfortable enough so that they will want to interact outside of class, where a large portion of learning actually takes place. On the other hand, it is also necessary for teachers to let students see the human side of them, and more importantly, for teachers to see the human side of their students. This human element creates an overall atmosphere of excitement and passion, which facilitates the ultimate objective of quality education. Indeed, we all remember our effective teachers, but those who had a special impact on our humanity, we remember with a genuine sense of appreciation and gratitude. & ///////////// service //////////// &solutions_txt1=Professional and Institutional Service &solutions_txt2=Professional Service Dr. Harras has been on the Technical Program Committees (TPC) or served as a reviewer for various conferences and journals including: IEEE Transactions on Vehicular Technologies (TVT), IEEE Transactions on Networking (ToN), IEEE Transactions on Parallel and Distributed Systems (TPDS), ACM Conference on Modeling, Analysis, and Simulation of Wireless and Mobile Systems (MSWiM), Communication Systems and Networks (COMSNETS), IEEE International Conference on Electronics, Circuits, and Systems (ICECS), IEEE Ad hoc and Sensor Networks (AHSN), IEEE Transactions on Mobile Computing (TMC), and IEEE Sensor, Mesh and Ad hoc Communications and Networks (SECON). He is also a member of the ACM and the IEEE. Institutional Service At Carnegie Mellon University, Dr. Harras has been the CS program director since Spring 2015, and serves as the chair of the Events and Outreach Committee (EOC) in the CS program. With the help of many people in various departments, this committee runs various events such as MindCraft, CS4Qatar for Teachers, CS4Qatar for Students, Internal Programming Competitions, Student Treasure Hunts, and High School Programming Competitions (HSPC). Khaled also served on several other committees including the CS hiring committee, IT assessment committee, Admissions assessment committee, Akhbar editorial board, CMU-Q's magazine, the Academic Advising board, and the first year experience committee. He has also previously served on the research committee. Finally, Khaled is currently the Computer Science club advisor. & &solutions_txt3=Sample Events &solutions_txt4=CS4Qatar
Computer Science for Qatar (CS4Qatar) has quickly grown to become one of the popular events in Qatar. Along with a large team at CMU-Q, we run workshops for high school students and teachers in order to raise computing and technology awareness in the community. &solutions_txt5=READ MORE &solutions_txt6=HSPC
The High School Programming Competition (HSPC) is an example of another major event we hold at CMU-Qatar. We expose high school students in Qatar to the excitement of problem solving through programming competitions similar to that held by the ACM. &solutions_txt7=READ MORE &solutions_img1=images/services01.jpg& &solutions_img2=images/services02.jpg& &solutions_readmore_title1=CS4Qatar &solutions_readmore_title2=HSPC &solutions_readmore_txt1=To be filled with CS4Qatar details and statistics soon. & &solutions_readmore_txt2=To be filled with HSPC details and statistics soon. & ///////////// other //////////// &partners_txt1=Non Academic Interests &partners_txt2=- Traveling: I have always enjoyed being exposed to various cultures and regions. Like many, I enjoy travelling and exploring the unique things one can experience in each country we visit. Countries I have lived in or visited include: Austria, Canada, China, Czech Republic, Egypt, England, France, Germany, Greece, Hong Kong, Hungary, Italy, India, Iraq, Jordan, Kuwait, Malaysia, Maldives, Netherlands, Portugal, Qatar, Saudi Arabia, Spain, Sri Lanka, Thailand, United Arab Emirates (UAE), and the United States of America (USA). - Reading: When not reading technical papers and books, I mostly enjoy reading about politics, history, and non-fiction novels. Some of the books that I recommend include: "My Life (Bill Clinton)", "The Audacity of Hope", "The Arabs", "Freakonomics", "The Fourth Star", "Ghost Wars", "Licensed to Kill: Privatizing the War on Terror", "Stones into Schools", and "Failed States". & &partners_txt3=Sports &partners_txt4=While this certainly counts as a non-academic interest, I felt that it is worth its own section.
