Biography

I was born in Munich, Germany, in 1975. I received a Master of Science from the University of Notre Dame, Indiana, USA, in 1999, and a Ph.D. from the University of Colorado at Boulder, USA, in 2003, both in electrical engineering. In the Fall semester of 1998, I was a visiting research student with the Coding Group at the University of Hawaii at Manoa, USA.

From 2004 until 2011, I was with the School of Electrical Engineering and Computer Science at the University of Newcastle, Australia, first as Lecturer, then Senior Lecturer, and finally Associate Professor. In the Spring semester of 2008, I was a Visiting Associate Professor with the Department of Electrical and Computer Engineering at Colorado State University, Ft. Collins, USA.

Since 2011, I have been Professor and Head of the Signal and System Theory Group, and in 2019, I was elected Dean of the Faculty of Electrical Engineering, Computer Science & Mathematics at the University of Paderborn, Germany. In 2018, I co-founded metamorphosis, which is a spin-off startup developing AI-based technologies for computer-assisted musculoskeletal surgery, and I have since served as its Chief Executive Officer.

I have received fellowships from the State of Bavaria, the Studienstiftung des deutschen Volkes (German National Academic Foundation), and the Deutsche Forschungsgemeinschaft (German Research Foundation).

From 2008 until 2012, I was an Associate Editor of the IEEE Transactions on Signal Processing, from 2010 until 2014 a Senior Area Editor for the IEEE Transactions on Signal Processing, and from 2015 to 2018 an Associate Editor for the IEEE Signal Processing Letters. I was the General Chair of the 2018 IEEE Statistical Signal Processing Workshop in Freiburg, Germany. From 2009 until 2014, I was a member of the IEEE Technical Committee on Machine Learning for Signal Processing, and from 2016 until 2021, a member of the IEEE Technical Committee on Signal Processing Theory and Methods. I am a Past Chair (2019-20) and currently Vice Chair of the Steering Committee of the IEEE Signal Processing Society’s (SPS) Data Science Initiative.
