About Me


Nikolaos Tziavelis is a PhD student at Northeastern’s Khoury College of Computer Sciences focusing on data management, advised by Professor Drs. Mirek Riedewald and Wolfgang Gatterbauer. He is from Athens, Greece. A member of the DATA Lab, Tziavelis earned his BS and MS in Electrical and Computer Engineering from the National Technical University of Athens. At Northeastern, Tziavelis’ research in databases includes top-k queries, data integration, and data exploration. He seeks to come up with new ways to reason about uncertain data and hopes to work on research in academia or industry.

What are the specifics of your graduate education (thus far)?

I am a first year PhD student and a member of the DATA Lab.

What are your research interests in a bit more detail? Is your current academic/research path what you always had in mind for yourself, or has it evolved somewhat? If so, how/why?

Coming to Northeastern, I was hoping to explore a variety of areas and topics related to databases and this is indeed my current focus. These include top-k queries, data integration and exploration.

What’s one problem you’d like to solve with your research/work?

My interests are all over the place at the moment. If I had to pick one, I would say coming up with new ways to reason about uncertain data.

What aspect of what you do is most interesting/fascinating to you? What aspects of your research (findings, angles, problems you’re solving) might surprise others?

I particularly enjoy the wide spectrum of approaches and techniques in this field of study. Database people have always had to deal with problems that range from theory to systems.

What are your research/career goals, going forward?

I hope to keep working on exciting research, either in academia or industry.

Where did you grow up/spend the most defining years of your childhood/young adulthood?

I grew up in Athens, Greece.
