Andreas Nautsch started studying computer science in 2008 at Hochschule Darmstadt (h_da) in a cooperative study program, he received his B.Sc. and M.Sc. degrees in 2012 and 2014, respectively. From 2008 to 2014 he worked at atip GmbH, Frankfurt am Main, as Software Engineer with focus on automatic speech recognition and speaker recognition for interactive voice response systems. In 2013, he went to an exchange semester at Mälardalens Högskola (MDH), Västerås, Sweden. In June 2014 he became Ph.D. student member of da/sec at the Center for Advanced Security Research Darmstadt (CASED), which became the Center for Research in Security and Privacy (CRISP). Since April 2015, Andreas is formal Ph.D. student of Prof. Dr. Max Mühlhäuser at the Technische Universität Darmstadt (TU Darmstadt) with research supervision of Prof. Dr. Christoph Busch at the Hochschule Darmstadt (h_da). He went to research stays at the ATVS biometrics group at Universidad Autónoma de Madrid, Spain from December 2015 to March 2016, and to Voxalys AB in Gothenburg, Sweden, during March 2017, respectively.
