In 2000 Thomas Cleff was appointed Professor of Quantitative Methods for Business and Economics at Pforzheim University. He holds degrees in Economics and Management Science from Pantheon-Sorbonne University in Paris (France) and the University of Wuppertal (Germany), and earned his doctoral degree at the University of Wuppertal (Germany). He was a senior researcher at the Centre for European Economic Research (ZEW) in Mannheim (Germany) from 1997 to 2000.

Since joining Pforzheim University, Thomas Cleff has fulfilled various roles: he spearheaded the development of the Bachelor’s double degree programme in International Marketing, was elected vice dean in 2012 and is dean of the Business School Pforzheim since 2014.

He is an expert in international accreditation and partnership programmes between institutions of higher education. In 2013 he became a board member of the Network of International Business and Economics Schools (NIBES) and has been its Secretary General between 2019 and 2023. Between 2016 and 2023 he served on the AACSB Initial Accreditation Committee (IAC) and since 2024 he is member of the AACSB Continuous Improvement Review Committee (CIRC). Between 2015 and 2020 he served on the Board of the AACSB European Affinity Group. As a member of various AACSB and EFMD Peer Review Teams (mostly as Chair of the PRT), he is and has been involved in the (re-)accreditation of many universities worldwide. Since 2014 he is a member of the International Advisory Board of the Education Quality Accreditation Agency (EQUAA), a South American association.

He is member of the International Academic Council of the School of Management at the National Taiwan University of Science and Technology (Taiwan), member of the Business Advisory Board of the Faculty of Management at the University of Warsaw (Poland), member of the International Advisory Board of the Brest Business School (France), member of the International Advisory Committee at Léonard de Vinci Business School - EMLV in Paris (France), member of the International Academic Board of the ESC Clermont Business School (France), member of the International Advisory Board of the Faculty of Economics and Business at the University of Maribor (Slovenia), and member of the International Advisory Board of Montpellier Management at the University of Montpellier (France).

On several occasions he has served as a visiting professor at universities outside of Germany. His main research interests are international marketing research, brand research, innovation research and industry studies. Between 2000 and 2018 he was research associate at the Centre for European Economic Research (ZEW), where he carried out a part of his research.

Thomas Cleff analyses corporate competition on international markets for goods and services. He designs empirical studies to identify success factors in brand and innovation management, especially which strategies are best suited for specific market conditions.
In the area of innovation research, Thomas Cleff worked together with ZEW Mannheim on a number of projects studying lead market analysis. Lead markets are considered as nuclei of global innovations that can displace innovations coming from other local markets. Identifying such “global dominating” markets is of signal importance for companies: a number of studies show that the lead market approach can positively influence the success of a company’s own innovations. Recent studies have shown that the success of first and second mover strategies also depend on the lead market qualities of first-mover markets. His future research will take into account under which conditions lead markets are unable to benefit from lead market advantages on their home market.
Another key factor for the success of a company is brand management. In recent years the concept of brand experience has received much attention in marketing research and practice. In this connection, the main questions are how brand experience can be measured and how it influences customer satisfaction, customer loyalty and brand value in online and on-site businesses. A number of empirical studies have found very different factorial structures of a brand experience scale. As a result, estimations of its influence on market value vary greatly. His future research will seek to operationalise brand experience and  market value for different industries and product fields (on-site and online) and demonstrate their correlations.
