Uğur Güdükbay is an associate professor at Department of Computer Engineering, Bilkent University, Ankara, Turkey. He received his Ph.D. degree in Computer Engineering and Information Science from Bilkent University, Ankara, Turkey, in 1994. Then, he conducted research as a postdoctoral fellow at Human Modeling and Simulation Laboratory, University of Pennsylvania, Philadelphia, Pennsylvania.
Dr. Güdükbay is doing research in the fields of Computer Graphics and Multimedia Databases and has research contributions in these areas. In the area of Computer Graphics, he developed techniques for the visualization of complex geometric environments, such as terrain height fields and urban models. He developed algorithms for stereoscopic view-dependent visualization of terrain height fields. He proposed a slice-wise representation for buildings, which is a data structure that stores buildings using axis-aligned slices, and exploited this representation to develop an occlusion culling algorithm for urban areas. Slicewise representation brings significant computational and storage gains.
Dr. Güdükbay also have contributions in various aspects of crowd simulation, such as impact of personality models on crowd behavior, path planning and modeling crowd behavior in emergency situations. He also involved in research activities for 3D scene representation technologies for 3D Television.
In the area of multimedia databases and content-based retrieval, he and his colleagues developed an MPEG-7 compliant video database system. The system allows text-based semantic, color, texture, shape, location, motion and spatio-temporal querying of video databases. They also worked on techniques for content-based retrieval of historical document archives.
He is also very active in terms of professional involvements. He is a senior member of both ACM and IEEE. He served as the Chair of IEEE Computer Society Turkey Section between 2004 and 2006. He co-chaired three conferences: IEEE 3DTV-CON 2011, IEEE 3DTV-CON 2008 and ISCIS'98, and was the guest editor of a journal special issue (Special Issue on Advances in Three Dimensional Television and Video, Signal Processing: Image Communication, Vol. 24, Nos. 1-2, January 2009.) He was on the Editorial Advisory Board of the computer graphics journal "Journal of WSCG" for 2009. He is a reviewer for many prestigious journals.
He served on the Program Committees of 1st IEEE Workshop on Modeling, Simulation and Visual Analysis of Large Crowds (MSVLC), November 7, 2011, Barcelona, Spain and the Pattern Recognition and Crowd Analysis Workshop (PRCA 2012) at ICPR 2012, Tsukuba, Japan. He also took conference duties for many prestigious conferences, such as ACM SIGGRAPH International Resources Committee Member, ACM SIGCHI Conference Reviewer.
He has authored/co-authored 47 peer-reviewed journal articles, 51 international and national refereed conference papers, 4 book chapters and edited three conference proceedings and a journal special issue. His publications received about 620 citations by other researchers, 320 of which is listed in ISI indexes. He has supervised/co-supervised 6 PhD Theses and 32 Masters Theses.
