Profile
Berkant Barla Cambazoglu received his BS, MS, and PhD degrees, all in computer engineering, from the Computer Engineering Department of Bilkent University in 1997, 2000, and 2006, respectively. He has then worked as a postdoctoral researcher in the Biomedical Informatics Department of the Ohio State University. He is currently employed as a researcher in Yahoo! Research. He has worked in several research projects, funded by the Scientific and Technological Research Council of Turkey, the European Union Sixth and Seventh Framework Programs, and the National Cancer Institute. In 2007, he received the Embodying the Vision award as a developer in the caBIG project. His research interests mainly include information retrieval, web search, and distributed computing. He has papers published in prestigious journals including IEEE TPDS, JPDC, Information Systems, and IP&M, as well as top-tier conferences, such as WWW, SIGIR, KDD, WSDM, and CIKM.
