Hi, welcome to my webpage! I am a 5th year PhD student at the Computer Architecture Lab (Archlab) at UC Santa Barbara (hint: I am currently on the market!). My area of research is energy efficiency in large-scale systems, which I pursue under the supervision of my advisor Prof. Fred Chong.

In particular, I investigate hardware and software mechanisms for energy-efficiency in datacenters. On the hardware side I have looked into low-power states for servers, while on the software side I have developed distributed middleware software for energy conservation. I also investigate energy-efficiency on enterprise servers. I have worked with developing SLA-driven power management for both the cpu and the memory (for DRAM and PCM).

Before joining the graduate program at UCSB, I earned a 5-year degree in Electrical and Computer Engineering from the National Technical University of Athens (NTUA). The final year of my studies I actually did at the Technical University of Munich, participating at the european exchange program ERASMUS.

Resume

For a detailed list the projects I have completed while at UCSB, as well as my professional experience, please look at my resume.

Foreign languages

My exchange year in Germany motivated me to learn new languages. On my arrival, the only foreign language I spoke was English; by the time of my departure, I had picked up German, Spanish and Portuguese. I am currently fluent in English, German, Spanish, besides my native language, Greek.

Misc

I studied classical music for 14 years (classical piano and theory), while I am currently involved with Argentine tango. I actually managed to combine my passion for Argentine tango with the one for Computer Science when I took the Pattern Classification class at UCSB. You can see the outcome of this in this report: class-report.
I am also into swimming and reading literature.
In 2009 I was the president of our local group of Women in CS.
I really enjoyed volunteering at the Olympic Games in Greece in 2004, and the World Cup in Germany in 2006.
Back in my undergrad days, I was the Public Relations responsible for a european student organization for the mobilization of students of technology (BEST).
