Dr. Felix Burkhardt

Dr. Felix Burkhardt ist ab Oktober 2022 Lehrbeauftragter am Fachgebiet Kommunikationswissenschaft. Er war vom 1. Oktober 2020 bis zum 31. März 2022 Vertretungsprofessor an der TU Berlin und leitete dort das Fachgebiet für Kommunikationswissenschaft am Institut für Sprache und Kommunikation.

Er ist seit September 2018 Forschungsleiter bei der audEERING GmbH, einer Firma die sich mit maschinellen Audioanalysen beschäftigt.

Nach einem Studium und Dissertation an der TU Berlin als Kommunkationswissenschaftler und Informatiker arbeitete Felix Burkhardt dort zunächst als wissenschaftlicher Mitarbeiter in DFG-Projekten. Von 2000 bis 2018 war er bei der T-Systems und Deutsche Telekom AG als Sprachtechnologieexperte angestellt. Außerdem ist er unregelmäßig Fachgutachter bei Konferenzen, Editor beim World Wide Web Consortium und als Gutachter bei der EU Horizon 2020 Vergabe beschäftigt.
