Short Bio

I am currently a scientist in Social Computing Group at Qatar Computing Research Institute (QCRI). Before joining QCRI in 2014, I was a postdoctoral researcher in the Teleimmersion Lab working with Prof. Ruzena Bajcsy at the University of California, Berkeley (UCB). I obtained my B.Sc. degrees, both in electrical & electronics engineering and computer engineering, and the Ph.D. degree in electrical engineering from Koç University, Istanbul, Turkey, in 2005 and 2010, respectively. I pursued my Ph.D. work in the Multimedia, Vision and Graphics Laboratory (MVGL) at Koç University under supervision of Prof. Engin Erzin, Prof. Yücel Yemez and Prof. A. Murat Tekalp. I received the Graduate Studies Excellence award in 2010 for outstanding academic achievement at Koç University.


Research

My research interests span the areas of multimedia signal processing, computer vision, machine learning and human-computer interaction. I have also recently gotten interested in wearable computing, quantified self and personal informatics.

Currently, I am working on two interesting topics. On one hand, I try to apply computer vision and machine learning techniques on large collections of social media images as well as aerial (UAV) images captured at disaster-hit locations for automated damage assessment and disaster response. On the other hand, I try to build an architecture for holistic view of individuals' health using rich data available from online social networks, wearable devices, mobile apps, and electronic health records.

During my postdoctoral studies at UCB, I built a multimodal data acquisition system, collected a comprehensive human action database and researched on human body motion analysis and action recognition from 3D data. I also worked on design and development of an interactive physical exercise system for remote coaching of elderly population.

My doctoral studies at Koç concentrated on multimodal dance performance analysis and music-driven dance synthesis and animation, as well as, facial expression analysis and speech-driven facial expression synthesis and animation.
