Tim Lee

The project studies how the hippocampal CA1 integrates olfactory and spatial information for goal-directed navigation. The position is a 3-year DFG-funded PhD (TV-L E13, 65%) starting April 2026, jointly supervised by Prof. Tobias Ackels at University Hospital Bonn and Dr. Oliver Barnstedt at the European Neuroscience Institute Göttingen. The project uses dual-colour miniscope calcium imaging, optogenetics, and behavioural experiments in freely moving mice. Application deadline is 31 January 2026, with applications sent by email.

PhD position in systems neuroscience!

Excited to start a new DFG-funded project together with @obarnstedt.bsky.social to study olfactory–spatial coding in CA1.
🔬 Dual-colour miniscope Ca2+ imaging
🐭 Freely moving behaviour & optogenetics

yay! looking forward to having you around in lab!

Come to MPINB! @mpinb.mpg.de

Thanks Misha for the shout-out!
It has been a truly mind-opening journey. WHOLISTIC is one step towards whole-organism neuroscience and a true physiological observatory - with extensions on the way! I am continually amazed by what the data reveals - so much remains to be discovered and mined.

🚨 PhD alert! IMPRS brain & behavior in Bonn just opened their calls for applications. Great PhD funding opportunities. Check it out! PS- I just joined their faculty, meaning you could do a rotation in my lab or even a PhD with me on spider sleep 🙃 Apply! 🚨

It was a good experience to step back and briefly take stock of the amazing progress in connectomics since I started working on this stuff (20 years ago!)

thanks as well to @natrevneuro.nature.com for the constructive editorial interactions.
