Professor at Goethe University Frankfurt. Cell biologist. Microscopist. Exploring subcellular architecture with super-resolution fluorescence microscopy.
Göttingen, Deutschland
Joined January 2018
I’m thrilled to share that I’ve been appointed as a Professor at Goethe University Frankfurt🎉 The Stephan Lab will use advanced bioimaging 🔬🧫 to explore how organelles collaborate to maintain subcellular architecture and metabolism. Find us now also on Bluesky: stephanlab.

STED microscopy reveals the intricate actin architecture in living cells at subdiffraction resolution! Once you go super-resolution, you never go back ;)
Live cell ACTIN imaging has never been easier with SPY650-FastAct_X! 1. Add the probe to the cells 2. Image 1h later SPY650 is highly suited for STED imaging. The image shows a confocal/STED comparison of the fine actin mesh in a live HeLa cell. image credits: @stephan_till

Nature - Research on Drosophila neurons shows links between the need to sleep and aerobic metabolism, indicating that the pressure to sleep may have a mitochondrial origin.

This poster is a must have for labs working on #MCS! A guide through the work of so many outstanding labs (apologies if we did not cite your work). Hang it in your office or lab, it will please your eyes and inspire your mind! Kudos to the driving force Antigoni Diokmetzidou! -LS
In their Cell Science at a Glance article, Antigoni Diokmetzidou & Luca Scorrano @LabScorrano summarise the mitochondrial contacts characterised in mammals, the mechanisms underlying their formation, and their principal functions. https://t.co/zKHSh7w3Wa

🎉 Exciting news! The SCALE Cluster has been named a DFG Cluster of Excellence—and the Lemke Lab is proud to be part of it! This is a major step forward in understanding the architecture of life at the subcellular level.
🎉 We’re absolutely thrilled: SCALE has been selected as a DFG Excellence Cluster! A huge thank you to our incredible team—this would not have been possible without your dedication and talent. 🙌 @dfg_public #Exzellenzstrategie #SCALEcluster 🧵

I’m thrilled to announce that my application to the Emmy Noether Program was successful! Over the next years, we’ll investigate how ER–mitochondria contact sites control the lipidome of both organelles. We’re looking for talented researchers to join us on this journey! 🎉🔬

Ever wondered how cells regulate the molecular traffic in and out of their nuclei? New research from Texas A&M University, supported by MINFLUX experts from the EMBL Imaging Centre, is helping uncover how molecules navigate the nuclear pore complex. https://t.co/PBz3kQc0DO
