I am a Ph.D. student in the Computer Sciences Department at University of Wisconsin-Madison, working with Shivaram Venkataraman, and also collaborate with Microsoft Gray Systems Lab.

My research interests mostly lie in the area of computer systems, with a focus at the intersection of data systems and machine learning. My latest research aims at improving existing ML-based database tuning tools.

Before moving to Madison, I received a M.Eng. in Electrical and Computer Engineering from University of Thessaly, Greece. In my undergraduate thesis, I worked with Christos D. Antonopoulos on characterizing programs behavior using low-level metrics that can be found on modern CPUs.

In the past, I have also interned at Microsoft Research, Redmond (2021), IBM Research - Zurich (2019), and CERN openlab (2017).
