Panel 1


I am a sleep scientist working at the Centre for Chronobiology in Basel, Switzerland. My research interests center around circadian rhythms and cognitive processing during healthy sleep and in patients with disorders of consciousness following severe brain injury. Currently, my main focus is the effects of artificial light on sleep, where I am specifically interested in its effects on brain processes during sleep (for more details see here).

Besides doing research, I also like talking and educating about it. I love doing science communication in German and English and am available as a speaker for events, workshops, or webinars. You find an overview of my activities here. If you would like to chat with me, please just drop me a line.

For more information, please find my CV here.

Panel 2




With my colleague Monika Angerer (University of Salzburg), I have been awareded the Christian-Doppler-Preis of the Land Salzburg 2021 (division Molecular Biosciences and Neurosciences).

I have joined the team of freelance #scicomm trainers at the German National Institute for Science Communication (Nawik). I am looking forward to share my passion for science communication and help others discover and develop their potential.

I was delighted to be invited as a guest for “Zwischentöne” on Deutschlandfunk, where, among other aspects, we chatted about sleep, precarious working conditions in academia, and my cello.


I am incredibly grateful and happy that my Ambizione” grant will be funded by the Swiss National Science Foundation. The funding allows me to continue my research at the Centre for Chronobiology at the University of Basel and the Psychiatric Hospital of the University of Basel.


Our new publication entitled “Association of transportation noise with sleep during the first year of life: a longitudinal study” has been accepted in Environmental Research.

With Amrei Bahr, Kristin Eichhorn, and Sebastian Kubon, I have written a piece on the #IchBinHanna protests for Nature Human Behaviour. With the hashtag #IchBinHanna, thousands of researchers protest against a German law that forces researchers out (btw. Austria adopted a similar law in May 21).


On 19 May, I gave an expert interview in “Die grosse TerraX Show” on ZDF.


Our new preprint “Association of transportation noise with sleep during infancy: a longitudinal study” is online on OSF.


On 22 March, I was a guest in the programme “Abendrot” (Saarländischer Rundfunk, SR1). We chatted about sleep and society, chronotypes, and what everyone can do for his/her sleep. The podcast is available here.

Our companion paper to the R package “SleepCycles” was accepted for publication in MethodsX. – Yay :).

On 15 March, I gave a talk at the “Woche des Gehirns” of the University of Basel on “Sleep Myths”.


On 11 January, I was a guest at the University of Kiel (Germany) in the lecture series “Science and alternative facts”. My talk on “Sleep Myths” is available here (in German).

Panel 3


In my research I study cognitive processing during sleep as well as how circadian rhythms brought about by the internal biological clock interact with higher cognitive functions including consciousness. For a short summary of these topics see below.

All publications are open access. If you nevertheless cannot find it or are just too lazy to search for it, just drop me a line and I will be happy to send you the PDF.
