Kevin Wilkinghoff

I am a postdoctoral researcher at Aalborg University, Denmark with the Pioneer Centre for AI, Copenhagen, Denmark and an active member of the DCASE community. From 2017 to 2024, I was a research associate at the Fraunhofer FKIE, Wachtberg, Germany, and in 2024 I was a visiting research scientist at MERL, Cambridge, MA, USA. I received my B.Sc. degree in mathematics at the University of Münster, Germany, in 2014 and my M.Sc. and Ph.D. degree in computer science at the University of Bonn, Germany, in 2017 and 2024, respectively.

My research focuses on anomaly and out-of-distribution detection for audio data, with applications such as acoustic machine condition monitoring, keyword spotting and sound event detection.
