about me

I'm a research scientist at the Hariri Institute for Computing and an adjunct assistant professor at Boston University. My research interests lie in distributed systems and databases.

Before joining BU, I was a visiting scholar at the RISELab, UC Berkeley, a senior researcher (oberassistent) at the Systems Group, ETH Zurich, a visiting research fellow at HKU, and a research assistant at the Information Systems Management Institute (IMSI) of the "Athena" Research Center, Greece. I obtained a 5-year diploma in Electrical and Computer Engineering in 2008, and a PhD in 2015, both from NTU Athens.

research interests

I work on data processing systems that are generally applicable, easy to use, and offer strong performance and security guarantees. Recent works include techniques that provide fast and meaningful insights into dataflow computations. The goal of my research in this area is to help data scientists answer questions like "Why does a dataflow return certain results?" or "Why is a dataflow execution slow?", which arise often in complex analytics. In the past, I've worked on (and still interested in) graph processing, data privacy, knowledge graphs, and software-defined networks.
