Version 2

Welcome! I am a postdoctoral fellow in the Department of Medical Physics and Acoustics at the University of Oldenburg. I investigate topics in the fields of music perception and acoustic signal processing. I am specifically interested in timbre perception, auditory scene analysis of listeners with normal and impaired hearing, and time-frequency processing of music signals.

[January 19, 2018] Paper accepted for JASA-EL: Timbral Shepard-illusion reveals ambiguity and context sensitivity of brightness perception“. I’m fairly excited about this project because it essentially shows that the good old Shepard illusion also works for timbre. This  stimulus class may open up a lot of possibilities. Please check here for some sneak-preview sound examples.

[December 5, 2017] Today, I found myself on the University of Oldenburg’s main page in a feature about my project on music perception and hearing loss. Here’s the full post.

[September 21, 2017] New opinion paper out: We’re trying to clean up some of the mess around the notion of timbre: Four distinctions for the `auditory wastebasket’ of timbre  published in Frontiers in Psychology.

[September 8, 2017] Best Paper Award for my paper “Iterative Structured Shrinkage Algorithms for Stationary/Transient Audio Separation” at DAFX 2017!


[September, 2017] Conferences are coming up: First attending the one and only Digital Audio Effects (DAFX) conference in Edinburgh, presenting work on transient/stationary separation. The week after, I give a talk on timbre at the Centre for Digital Music (Queen Mary University of London), followed by a conference on music perception and hearing aids in Leeds. The weekend will be spent back in Hamburg, Germany, with a poster at the annual Meeting of the German Society for Music Psychology. Looking forward to two inspiring weeks!

[May 16, 2017] Very glad to be accepted as an associated junior fellow at the Hanse Wissenschaftskolleg. The fellowship will give me the opportunity to organize exciting international events on musical auditory scene analysis.

[Mar 10, 2017] I am very happy to announce that my project TIMPANI – Test, Predict, and Improve Musical Scene Perception of Hearing-Impaired Listeners will be funded by a Marie Skłodowska-Curie Individual Fellowship, part of the Horizon 2020 framework of the European Commission. This project will enable me to continue research at the University of Oldenburg and delve into the complex issue of sensorineural hearing loss and its effects on musical scene perception. Besides gaining a better understanding of the involved perceptual processes, a goal is to develop signal processing strategies for better music perception with hearing aids.

[Feb 17, 2017] Videos of the Berlin Interdisciplinary Workshop on Timbre are online!

[Jan 14, 2017] Hooray to Helmholtz! With my Montreal teachers Stephen McAdams and Bob Hasegawa in Berlin for the timbre workshop, we managed to take a snowy picture with sound color forefather Hermann von Helmholtz. Thanks for your inspiration, Hermann!



[Jan 12-13, 2017] The Berlin Interdisciplinary Workshop on Timbre was a great success! We had a broad spectrum of talks, tons of discussions, and lots of exchange. More reports soon. We will also upload most of the talks as a resource for the community.

[Nov 15, 2016] Announcing the BERLIN INTERDISCIPLINARY WORKSHOP ON TIMBRE, Jan 12-13, 2017 at the Musical Instrument Museum Berlin. We managed to gather a wonderful crowd of timbre geeks. Looking forward to an inspiring event!
