Hakan Ferhatosmanoglu is a Professor at the University of Warwick, and a Fellow at the Alan Turing Institute, the UK's national institute for data science and AI. His research interest is in building data systems for scalable search and data analytics. This involves management of information from multiple sources while protecting the privacy of data subjects. An example application is to learn aggregate mobility patterns over large spatio-temporal databases. He has published in the premier venues of data systems and analytics, including VLDB, KDD, SIGMOD, PODS, ICDE, SIGIR, CIKM, WSDM, ACM Multimedia, VLDBJ, IEEE T. Mobile Computing, TKDE. He has been the Principal Investigator of more than 20 funded grants. He has supervised dozens of postgraduate students, including more than 10 PhDs to completion. Advisees have moved to work in faculty positions at major research universities, and companies including Google, Amazon, Facebook, Oracle, Teradata, Microsoft. He received several Research Career Awards, including from US Department of Energy, National Science Foundation, and Alexander von Humboldt Foundation.
