Now that the science days are over, I can happily share some of my designs :)

Thanks to all the @in-code.bsky.social members who made these days a success! It was intense but worth it!

And huge thanks to @sophiekb.bsky.social that was in charge of making this happen

Happy to share that I just started a W2 professorship at the University of Bremen! Yay tenure! While I already start teaching now, the lab will stay in Freiburg until May while we get things ready. Super excited about this new chapter! We’re also hiring! Please get in touch if you’re interested!

🧠🧪 #Neurons can communicate via a hidden network of #nanotubes. Chang et al. (2025) show dendritic nanotubes as #actin-based conduits transferring Ca²⁺ + cargo, rising before plaque deposition in 🐁 #cortex. This overlooked pathway may expand views of neuronal communication beyond #synapses.

Happy to share our new paper with Mathilde Nordlund and Julie Koenig out @currentbiology.bsky.social. We used virtual reality in mice to study hippocampal distance coding. Our results suggest a primary contribution of grid cells to distance over cue-dependent place cell coding.

Check out new work from our lab! We developed a new way to directly control the precise timing of interneurons during behavior and found that theta phase locking is a causal mediator of seizure susceptibility in both healthy and epileptic mice.
🚨New preprint alert🚨
We used closed-loop optogenetics to causally test the importance of inhibitory spike timing in network function and found that manipulating PV+ cell theta phase locking in the dentate gyrus can shift seizure susceptibility (both ways!)

The main project from my PhD, in collaboration with Manuela Allegra and @schlab.bsky.social is now available as a preprint! We wondered how the hippocampus and the visual cortex may differ in the way they refine sensory inputs into internal representations

Sensory inputs are progressively transformed into internal representations of the environment along the cortical hierarchy. How does the behavioral relevance of these inputs affect this encoding? Usin...

Your brain doesn’t just passively track time ⏳ - it structures it.
In @Science.org we show that activity in 🧠 memory circuits (LEC) drifts constantly, but makes sharp jumps at key moments, segmenting life into meaningful events. (1/2)

Almost all Nobel Prizes are awarded for work that is exploratory, or absolutely basic science with no obvious commercial or medical benefit.

You cannot predict where advancements come from, so you have to invest in science and scientists.

Targeted (corporate) science investment will never do this.
Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪
