Christian joined Facebook as a research scientist in 2013 due to the acquisition of Mobile Technologies. At Mobile Technologies, he was one of the core developers of “Jibbigo”, an on-device speech-to-speech translator for mobile devices, where he worked from 2007 until 2013, first as a research scientist and later as director of research. Christian received a doctorate for his work on simultaneous translation systems of lectures and speeches from University of Karlsruhe (TH) in 2008 in which he developed core components for a first-ever simultaneous lecture translation system, including innovations in speech recognition, segmentation, adaptation and work on real-time and latency requirements for simultaneous speech translation systems. At Facebook, his team is focusing on advancing the state-of-art of speech recognition and human machine interaction by executing research on self/ unsupervised learning, domain transfer learning, on-device modeling, multi-microphone recognition, or acoustic event detection.
