#CryoEM and structural biology at Monash University
Very well deserved! A great reward for a a lot of hard work 😊
Earlier this year, I was incredibly honoured to receive the Premier’s Award for Health and Medical Research in the Basic Science category.

This recognition is a huge testament to the amazing work of our entire team. 🙌💥🎉

Seed to sub-Å!
We just solved crambin at 0.85Å with #MicroED straight from spontaneous nanocrystals, phased ab-initio from a 5-res helix. Video shows diffraction ➜ ugly start map ➜ beautiful spheres. Preprint: www.biorxiv.org/content/10.1...

We used cryoET and biophysical approaches in vitro together with molecular biology in differentiated cells to show that chromatin compacted by PRC1-CBX8 is porous and accessible while PRC1 is dynamic in it. 🧪🧬 #cryoET #Epigenetics #Polycomb www.nature.com/articles/s41...

Here the authors show that a gene-inactivating protein complex packs inactive genes into a dynamic and accessible structure. The study challenges the traditional views that restricted accessibility an...

🧵 1/ We’re excited to share that our new paper with @adrianbracken.bsky.social lab is out 🎉 In this study (which began over 10 years ago!), we explore the biology of PRC2 and PRC1 in non-dividing cells. We also explore the effects of PRC2 inhibitor drugs on these cells. Here’s what we found👇

Very cool! 😁
The PDBs for our TSC structure are now available!

To put the size of TSC in perspective, here's a ribosome... this thing is enormous. 🤩

Excited to see our latest study published!

We report several structures of the intriguing LYCHOS (GPR155) protein revealing a chimeric structure of a GPCR and a PIN-like transporter domain #cryoEM #mTOR #GPCR #auxin
