Biography

Ina Kodrasi received the Master of Science degree in Communications, Systems, and Electronics in 2010 from Jacobs University Bremen, Germany, and her Ph.D. degree in 2015 from the University of Oldenburg, Germany. From 2010 to 2015 she worked as an early stage researcher at the  Signal Processing Group of the University of Oldenburg. From 2010 to 2011 she was also with the Fraunhofer Institute for Digital Media Technology, project group Hearing, Speech and Audio Technology in Oldenburg where she worked on microphone array beamforming. Since December 2015 she is a postdoctoral researcher at the Signal Processing Group of the University of Oldenburg in the field of speech dereverberation and noise reduction.

Research Interests

  • Multi-microphone dereverberation techniques
  • Microphone array processing for signal enhancement
