I am an Assistant Professor of Computer Science at Boston University, Director and Founder of the BU Data-intensive Systems and Computing (DiSC) lab, and part of the BU MiDAS group. My research is in the area of data systems, focusing on novel cloud data management architectures, complex hybrid transactional/analytical workloads, and new hardware (like non-volatile memories and heterogeneous computation units).

Before joining BU I was a Research Associate at Harvard University. From 2014-2017 I was a Postdoctoral Researcher at Harvard University in the Data Systems Lab with Stratos Idreos, where I was supported by a SNSF Postdoc Mobility Fellowship. I received my PhD (2014) from EPFL, where I worked in the Data-Intensive Applications and Systems Lab on studying data systems architectures for analytics exploiting new storage hardware with Anastasia Ailamaki. I obtained my MSc (2008) in Computer Systems Technology, and BSc (2005) in Informatics and Telecommunications from the University of Athens, Greece. I have also been at IBM Research as a PhD Intern in 2011, and a junior researcher in the University of Athens and the National Technical University of Athens.

Outside of the office I enjoy biking, playing basketball, and studying history.
