I am a Professor in the Department of Computer Science, University of Surrey where I am Joint Head of the Distributed and Networked Systems (DANS) group, and also affiliated with the Secure Systems Research Group and the Surrey Centre for Cyber Security.
Prior to joining University of Surrey in 2020, I was a Professor and the Head of the Centre for Distributed and Global Computing at Royal Holloway, University of London (RHUL) from 2012 – 2019, a Research Staff Member at IBM Research from 2005 – 2012, and a Postdoctoral Associate in the Theory of Distributed Systems group at the Computer Science and Artificial Intelligence Laboratory (CSAIL) of Massachusetts Institute of Technology (MIT) from 2003 – 2005.
I obtained my PhD, MSc, and BSc degrees in Computer Science from Hebrew University of Jerusalem in 2003, 1998, and 1993 respectively.
My research interests are broadly in the area of distributed computing and systems spanning both theory and practice. I am particularly interested in real-world problems seeking to uncover deep tradeoffs (such as lower bounds and algorithms) and their implications for the system engineering practices. My current focus is on scalability and robustness in modern large-scale computing and storage infrastructures, such as blockchains, cloud services, large-scale data centres, Internet of Things (IoT) platforms, and multi-core architectures. I am involved in a number of projects tackling various challenges arising in these environments including Byzantine consensus, distributed transactions, data replication, data diffusion, coding and caching among others.
I have co-authored several popular surveys and position papers on cloud computing, distributed storage, and group communication.
My work is being supported by IBM Shared University Research Award, Coleman-Cohen Exchange Programme Grant, Royal Society International Exchanges Grant, and Facebook Faculty Award.
I am actively collaborating with a number of academic institutions and industrial partners world-wide including IMDEA Software Institute, Technion, Tel-Aviv University, Emory University, Cornell, KTH, and IBM Research.
I have been fortunate to work with a number of talented students and postdocs.
I am a co-inventor of several patents.
