Panagiotis Kalnis is a Greek academic who specializes in cloud computing and databases.
After earning undergraduate and master's degrees from the University of Patras in Greece, Kalnis completed a PhD at the Hong Kong University of Science and Technology.[1]
Kalnis is a professor of computer science at the King Abdullah University of Science and Technology. While working there, he along with colleagues from Thomas J. Watson Research Center have developed a Pregel system called Mizan.[2] He previously worked at the National University of Singapore, where he and his colleagues developed a tree traversal algorithm which showed suggested edit distance which in turn reduced computation cost.[3] In 2009, along with Gabriel Ghinita, Panagiotis Karras, and Nikos Mamoulis from the University of Hong Kong, he created heuristics to solve the problems posed by k-anonymity and l-diversity data privacy models in linear time.[4]
