Wissenschaftlicher Werdegang

Christof Weinhardt studierte Wirtschaftsingenieurwesen und promovierte im Jahre 1989 in Wirtschaftswissenschaften an der Technischen Hochschule in Karlsruhe (TH). In seiner Forschung an den Universitäten Bielefeld und Gießen konzentrierte er sich verstärkt auf Themen der Wirtschaftsinformatik. Derzeit ist er Professor des Instituts für Informationswirtschaft und Marketing (IISM) am Karlsruher Institut für Technologie (KIT). Er leitet die Gruppe "Information and Market Engineering" (IM).

Von 2002 an war er Prodekan für Forschung und von 2012 – 2014 Dekan an der Fakultät Wirtschaftswissenschaften am KIT. 2010 – 2014 war er Mitglied Strategie- und Forschungskommission des KIT. Außerdem ist er Gründer und Direktor des Karlsruher Research Instituts (KSRI) – die erste „Industrie des Campus“-Gründung des KIT – und Direktor des Forschungszentrums Informatik (FZI), die Transferorganistaion des KIT für ICT.

2006 wurde er Mitglied in der Beratungsgruppe des Deutschen Industrieverbandes (BDI) „Internet der Energie“. Seit 2008 ist er gewählter Fachgutachter der DFG für Wirtschaftswissenschaften. Für die Zeit von 2010 – 2013 wurde er als Sachverständiger in die Enquete-Kommission „Internet und die Digitale Gesellschaft“ des Deutschen Bundestages berufen. Zusammen mit seinem Forscherteam arbeitet er an einer Vielzahl von Forschungsprojekten - sowohl in der Wissenschaft als auch in der Industrie.

Mit seinem akademischen Hintergrund in Wirtschaftsingenieurwesen, Betriebswirtschaft, Volkswirtschaft und Wirtschaftsinformatik konzentriert sich seine Forschung auf interdisziplinäre Themen aus dem Bereich Market Engineering mit Anwendungen in der IT-Dienstleistungsindustrie, in der Energiewirtschaft sowie in Finanz- und Telekommunikationsmärkten. In diesen Bereichen ist er Tagungsleiter, Mitherausgeber und Gutachter für zahlreiche internationale Konferenzen und Zeitschriften, veröffentlichte mehr als 150 Artikel in renommierten Fachzeitschriften und Bücher und erhielt eine Reihe von Auszeichnungen für seine Forschung und Lehre.
