His PhD dissertation was awarded the prestigious Certificate of Recognition and Honorable Mention in 2009 by ACM SIGKDD. From March 2009 until February 2010, he was appointed as a postdoctoral research fellow in the Department of Biomedical Informatics at Vanderbilt University, working on privacy for medical data sharing. In March 2010, he joined IBM Research in Zurich as a research scientist in the Information Analytics group. In 2011, he was nominated as a member of the IBM Business and Technical Leadership Resources program.

Aris’ research interests are in the areas of databases, data mining, privacy-preserving data mining, privacy and anonymity in trajectories and location-based services, privacy in medical data sharing, and knowledge hiding. In these areas, he has given many seminars and two tutorials, published more than 80 research works including four Springer books, and authored ten patents. Aris is a regular reviewer for top-ranked journals and he regularly serves on the program committees of prestigious conferences. In addition to his role as a category editor for ACM Computing Reviews, he is an editor for IGI’s International Journal of Knowledge-Based Organizations.
