I am a final year PhD candidate with the Bio-Inspired VLSI Circuits and Systems Group under the supervision of Dr. E.M. Drakakis. My research currently focuses on the trade-offs involved in the design of very low-power, fully integrated front-ends for pulse oximeters, that will enable the continuous monitoring of human blood oxygen levels with portable devices with increased battery life and accuracy.

In the past I have worked on algorithms to improve the long-term accuracy of electrochemical sensors and the design of very-high dynamic range and low-power integrated continuous time filters based on non-linear compressive functions, and more specifically hyperbolic-sine (Sinh) filters. I am interested in all aspects of analog integrated system design, with a focus on sensor interfaces and non-linear systems.

I received my Diploma in Electrical and Computer Engineering from Aristotle University of Thessaloniki, Greece in 2006, with a GPA of 9.45/10. Subsequently, I attended an MSc course in Analogue and Digital Integrated Circuit Design at Imperial College London, UK from which I graduated first in my year in 2007. From 2006 to 2008 I have been a scholar of Bodossaki Foundation, Greece.

In my free time I like to argue about politics,  play four-hour long board games, watch pretentious and obscure movies, learn languages and strum a guitar.
