Scientist. She/her. I like cryoET, fluorescences microscopy, and cell biology.
Developing cryoCLEM methods in the Mahamid lab at EMBL Heidelberg. Formerly studying NPCs in the Beck Lab at MPIBP Frankfurt. MBL Physiology’23 alumn.
Happy to see that our paper on NPC (a)symmetry inspired a newspaper article!

Great work of @deglushk.bsky.social from my PhD lab @mpibp.bsky.social on how to get more information out of all the membranes you see in cryoET data!

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

Check out our preprint! With new molecular mechanisms, 140 subtomogram averages, and ~600 annotated cells under different conditions, we @embl.org were able to describe bacterial populations with in-cell #cryoET. And there’s a surprise at the end 🕵️

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells?

How many photons are in a GFP? — more than last year, and more than you thought. Here's a simple, cheap, and practical method to break a fundamental limit in fluorescence microscopy. But it only works in light sheet!

The MPG is advertising directorships - powerful positions for which recruitment is usually started by them reaching out to potential candidates. Let’s hope this open call will get some great (but maybe overlooked) scientists on the candidate list and doesn’t accidentally select for oversized egos…
Director at Max Planck - a unique position! The Open Call for Expressions of Interest in Max Planck Directorships is open now and can be submitted by the 31st of October 2025. ➡️ mpg.de/directors - Please share the Open Call among potential candidates.

Beautiful cutting-edge in situ cryoET work (with very pretty figures) from the Grange lab!

Great to see how the field is getting closer to doing structural work in tissues and how development in FIB technology, lift-out procedures, and correlative light microscopy contribute!

1. Can you figure out where I was standing when I took this picture?

ChatGPT could. Given the photograph (scrubbed of all header information), the new chain of thought model, ChatGPT o.3, was able to pinpoint the location with a few meters.
