Grigorios G. Anagnostopoulos is a Senior Lecturer (Maître d'enseignement) at HES-SO University of Applied Sciences and Arts Western Switzerland. Colleagues describe them as "Greg possesses natural personality traits that I have rarely encountered in a single individual. Stemming from a core of honesty and integrity, he is an active listener, direct in his communication, and at the same time warm and affable. These qualities made him a pleasure to work with in the time we shared as colleagues. He was the analytical mind invited to every brainstorm session, the critical eye with constructive feedback that kept us on our toes, the voice of reason that was key in decision-making. Technically, Greg is a very strong asset in today's IT market. His ease with mathematics and statistics is invaluable when modeling systems and understanding data. His knowledge of algorithms and experience in programming allow him to also go beyond the conceptual phase and deliver clean results. His recent success with optimization algorithms for positioning applications is one such example, where he singlehandedly researched, modeled and implemented a working system. I wholeheartedly recommend Greg to any team, sure that he will provide full commitment to the mission and an enthusiastic approach to his work from day one." and "I’ve had the chance to work in the same research group with Grigorios for about three years. Working next to him was enlightening, scientifically wise. His extremely strong analytic mind made him the main scientific contributor of the R&D group. Thanks to his great scientific conscience, he is constantly publishing papers expanding the state of the art while pushing us all in being always more precise in our work. Grigorios never hesitated to spend hours on helping colleagues solving problems that are not his responsibilities. By being patient, listening and of a very high scientific level, his insights were always on spot and unlocking. Grigoris is one of these persons that always become the pillar of a group. His wisdom, charisma, knowledge and kind heart make him the natural person that everyone goes to for advice and recommendation. On a personal note, he is one of the few persons I’ve worked with that I will try my best to keep contact with through time. Therefore, I naturally recommend Grigorios to anyone with closed eyes. "
