Biography
Christoph's research interests include multichannel speech separation, beamforming, dereverberation, and automatic speech recognition for meetings, with a focus on combining statistical models and neural networks. He studied Electrical Engineering at Paderborn University, Germany, and held research internships at Microsoft Research in Redmond, USA (2017), and at MERL in Cambridge, USA (2022) before joining MERL as a Visiting Research Scientist.
