Gregoris Mentzas is full Professor of Management Information Systems, School of Electrical and Computer Engineering, National Technical University of Athens (NTUA) and Founder and Director of the Information Management Unit (IMU) at the Institute of Communication and Computer Systems (ICCS).
His main research focus is on AI-enabled decision making: augmenting human intelligence with data-driven approaches and using Artificial Intelligence to elevate human decision-making competence. Specifically his current research concerns the development of prescriptive data analytics for digital assistants in industry 4.0, the integration of human feedback in reinforcement learning for financial applications and the use of big data analytics in applications like personalised health, smart mobility, technology acceptance and water management.
Prof. Mentzas has published 4 books and more than 350 papers in international peer-reviewed journals and conferences, has 5 best papers awards. He sits on the editorial board of five international journals and has served as (co-)Chair or Program Committee Member in more than 55 international conferences. He has led or contributed in more than 50 European research and development projects conducted in collaboration with leading technology firms like SAP, IBM, HP, Siemens, Software AG and ATOS.
Prof. Mentzas is in the top 2% of highly cited scientists globally in a publicly available list of more than 7 million scientists in all areas of research and technology (22 scientific fields and 176 sub-fields). The list, which was published in 2021 in the journal PLOS Biology, retrieved data from the SCOPUS database and used a range of parameters for each scientist’s research contribution and influence, analyzed data of 7 million scientists with at least five published articles on the SCOPUS database. As a result, a list of the top 2% scientists from all scientific subjects was compiled. The classification takes into account standardized information on citations like the h-index, co-authorship adjusted hm-index,
Research carried out by his group has led to the establishment of three internet technology companies. His experience includes twelve years of management consulting in corporate strategy and information systems strategy. He holds a Diploma Degree in Engineering (1984) and a Ph.D. in Operations Research and Information Systems (1988) both from NTUA.
During 2006-2009 he served as member of the Board of Directors of the Institute of Communication and Computer Systems, while in the 2010-2019 period he was Director of the division of “Industrial Electric Devices and Decision Systems” at the School of Electrical and Computer Engineering, NTUA.
Parallel to this academic work he is an enthusiast black and white photographer, see his work at http://www.gregorismentzas.com.
Research activity: In 1997 Prof. Mentzas established, and has since been leading, the Information Management Unit (IMU) http://imu.ntua.gr, a research laboratory at the National Technical University of Athens. The mission of IMU is to enable the development of knowledge-driven organisations. IMU focuses on technological research in the areas of: knowledge & semantic technologies; service and process engineering; and decision management, while the major application domains are within the domains of: digital enterprise systems; electronic governance; and collaborative and social systems. IMU is a member of the Big Data Value Association (BDVA) , a fully self-financed non–for-profit organization, which aims to boost European Big Data Value research, development and innovation and of the Networked European Software and Systems Initiative (NESSI), the European Technology platform dedicated to Software and Services. Since its establishment IMU has actively contributed in fifty three (53) research and development projects. The total funding from research grants administered by IMU since 1997 exceeds 16.0 million euros.
