Panos Kalnis

Principal Investigator

Introduction

I am an Associate Professor in Computer Science in the Division of Mathematical and Computer Sciences and Engineering, King Abdullah University of Science and Technology (KAUST). Prior to joining KAUST, I was an assistant professor in the Department of Computer Science, National University of Singapore (NUS).

In the past I was involved in the designing and testing of VLSI chips at the Computer Technology Institute, Greece. I have previously worked for several companies within database designing, e-commerce projects and web applications.

I received my Ph.D. from Hong Kong University of Science and Technology and a Diploma in Computer Engineering from the University of Patras, Greece. In 2009 I was on sabbatical from Stanford University.

Research Interests

​I am a member of the InfoCloud @ KAUST group. I work on Databases and Information management. Specifically, I am interested in: Database outsourcing and Cloud Computing, Mobile Computing, Peer-to-Peer, OLAP, Data Warehouses, Spatial-Temporal and High-dimensional Databases, GIS, Security - Privacy - Anonymity
