I am on the academic job market. Please reach out to me if you are hiring!

About.

I am a final-year Ph.D. candidate in the Department of Computer Science at UC Santa Barbara and a research affiliate at Lawrence Berkeley National Laboratory. My interests tend to sit within the field of computer architecture but are not limited to this area.

My research leverages a deeper understanding of the nature of computation and underlying devices to develop new paradigms and cross-stack solutions for emerging applications and technologies. Currently, I am focusing on advancing computational temporal logic for energy-efficient processing in systems ranging from in-sensor processors to exotic supercomputers. Moreover, I am actively involved in ArchLab's efforts to develop new languages and tools to model, design, and evaluate semiconductor- and superconductor-based computer platforms. For my latest updates, please take a look at my publications page and scholar profile.

In addition to my science and engineering passions, I am intrigued by the challenge of turning visionary ideas into real-world solutions. To demystify entrepreneurship and sharpen my business skills, I am attending UCSB's Technology Management Program.

Prior to joining UCSB, I obtained my Master's degree in Electrical and Computer Engineering from UC Davis. My alma mater is the National Technical University of Athens in Greece.

Besides academia, I have worked for Xilinx and Athens Information Technology - Intracom Holdings.

Superconductor electronics are (literally) cool and have been around for a while. However, they have only recently gained interest from computer systems researchers. To accelerate innovation at the intersection of these two fields, I built the JJUNCTION. If you want to share a comment, suggestion, or new material, drop me a line!
