Summary

Dr. Lazaros Polymenakos (MIT '95) is full professor at Athens Information Technology, head of the Autonomic & Grid Computing Laboratory and coordinator of the MSIN-Athens Master Program offered in collaboration with Carnegie Mellon University (CMU). He is an adjunct professor of the Information Networking Institute of CMU since 2004, and has served as academic visitor (2004, 2006) to the ΙΒΜ T. J. Watson Research Center, NY, USA. His academic interests focus around the are of intelligent systems, autonomic systems, multimodal interfaces and grid computing. At AIT he founded and organized the Autonomic & Grid Computing Laboratory which amounts to day 5 professors at different seniority levels, 3 Ph.D. students and 4 researchers. Before joining AIT (in the years 1995-2003) prof. Polymenakos was at the Human Language Technologies group, ΙΒΜ T. J. Watson Research Center, New York, and founded (1999-2003) a research branch embedded in IBM-Hellas, numbering 10 people, to research multimodal interfaces and to develop Greek speech recognition & synthesis systems (desktop, telephony). He has also worked as visiting professor (1996) at Rutgers University, New Jersey, USA, as visiting researcher at the National Technical Univeristy of Athens (1198-1999), and as researcher at Thinking Machines Corporation, MA, USA (1992-1993).

Prof. Polymenakos has a long history as the inceptor and/or technical leader for European and National funded research projects which had strong scientific impact and have been judged as representative of the corresponding research area. Over the past 8 years(2000-2008) prof. Polymenakos has attracted more than €7 million for 15 research projects from European, National and Industrial sources; he has also participated for the execution of several other projects.

Prof. Polymenakos’ research and academic work has led to more than 40 publications in international scientific journals, 1 edited book, 10 book chapters, and more than 50 papers in reviewed international conferences –– receiving Best Paper Αward (3rd place) at ΙΕΕΕ CIC-2006. He has two international patents (USA and EU) and contributed to the International Standard for multimodal interaction (2001) at the ETSI –AURORA standardization group. He has served in the organizing committee of several international conferences (WebSci-09, ΑΙΑΙ-07, PIMRC-07, ΑΙΑΙ-06, ICSLP-06) some of which are renowned in the field and were attended by more than 1000 participants. Prof. Polymenakos has also done research community work by serving as a reviewer in several international scientific journals and conferences, as member of the evaluation committees for European and national funded projects, as member of scientific consultation groups for Europe and Greece shaping future research funding frameworks.

9. Jane Hagstrom (Professor, Department of Information and Decision Sciences Associate Professor, Urban Transportation Center) refers to the algorithm described in my thesis in her paper: “A note on function inversion for the algorithm of Bertsekas, Polymenakos, and Tseng for network flow problems with convex, separable costs”, 1998. This citation is notable because it establishes the algorithm as named after the authors, and it provides a link for the algorithmic framework proposed by my thesis to non-linear, non-invertible mathematical problems.
