Zoran Constantinescu got his MSc (1997) at the Department of Computer Science from the Politehnica University of Bucharest, Romania. He has been working since, both in the Software Engineering industry and in Higher Education. He got his doctoral degree in Computer Science (2008) from The Norwegian University of Science and Technology, Trondheim, Norway, with a thesis on a desktop grid computing approach to scientific computing and visualization. In fact, he has developed from scratch a new open source desktop grid computing system, named QADPZ, and has proved its viability by testing it on some scientific computing and visualization experiments. Since QADPZ became openly available in 2003, thousands of users around the world have been using it for their computationally intensive tasks and contributed with their feedback to the system’s improvement. Broadly, his research interests include parallel and distributed computing, desktop grid computing, GPS systems, and embedded systems, and he has published 25 research papers dealing with these topics. He is very committed to the open source world and actively participates in this endeavor.
