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. My ongoing research focuses on Secrecy, a system for secure collaborative analytics in multi-cloud and federated environments. Secrecy enables multiple data owners to perform computations on their collective private data, while keeping the data siloed from each other (and from external untrusted entities) with provable security guarantees.
