I am a Computer Science graduate student at the University of Maryland, College Park. I am primarily interested in compiler technologies for efficient execution of parallel programms while promoting ease-of-programming.

A picture is worth 1K words right ? So this is already a lot. To top that I was born in Athens, Greece, but I am half French on my mother's side. I went to undergrad at NTUA, got my degree in Electrical and Computer Engineering with a Thesis in Complexity Theory under S.Zachos, and came to the University of Maryland to pursue a Ph.D.

Research

I am doing research in the area of compilers for parallel architectures, and specifically for XMT. I am co-advised by Dr. Rajeev Barua and Dr. Uzi Vishkin. So far I have implemented a basic but stable compiler for the XMTC language, a small extension of C for XMT. This compiler was used with big success in the class of Parallel Algorithms taught at the University of Maryland in Spring '07. I am now working with G. Caragea to add language and target specific optimizations and functionality.
