I recently obtained my PhD in Computer Science at Hasselt University, Belgium, where I work with professor Frank Neven (advisor). I'm a proud member of the Databases and Theoretical Computer Science Research Group and PhD Fellow of the Research Foundation - Flanders (FWO). Prior to starting a PhD I obtained an MSc degree in computer science - databases.
My research interests lie in the area of cloud computing and big data computations. My current research focuses mostly on the principles of database management, with as a red line the study and development of formal approaches to querying big data. Specific topics were I work(ed) on are: multi-join optimization in parallel and distributed systems, Datalog evaluation in asynchronous systems, and in general, the study of logical properties over queries that facilitate efficient query evaluation in those systems. This research has been awarded with best paper awards at the ACM PODS conference (year 2014 and 2015).
In 2016 I resided three months at the database group of the University of Washington, Seattle, to work with professor Dan Suciu. During this stay we developed a parallel join algorithm that runs with worst-case optimal communication cost. In 2017 I visited the database group of the University of Wisconsin-Madison for almost three months to collaborate with professor Paris Koutris. I also did short visits to Lehrstuhl Informatik 1 at the Technical University of Dortmund, Germany, to work with professor Thomas Schwentick.
