I’ve officially started my lab at Monash University! 🎉 We’re diving into #cellgrowth and #lysosome biology, through the lens of molecular #structure and mechanism. I’m thrilled to say that PhD student scholarships are available—so please share widely and get in touch if you’re interested. 🤩

cyoEM, cell singling across membranes
At #BPS2026? 🧬 Come talk structural biology & mTORC1 signaling! I'll be at Poster B220 this Tuesday, 2:45–3:45 PM. I’m also building the Cui Lab at CU Anschutz and looking for postdocs/students interested in Cryo-EM and ML. Let's chat! 🧪🏔️ #Biophysics #CryoEM #StructuralBiology
This one is a bit of a departure from the usual and definitely a work in progress! We found that by using ab initio reconstruction at very high res, in very small steps, we could crack some small structures that had eluded us - e.g. 39kDa iPKAc (EMPIAR-10252), below. Read on for details... 1/x

Finally in @nature.com 🎉 We uncovered step-wise mTORC1 activation on membrane: RAG–Ragulator recruits, RHEB pushes closer, and direct membrane contacts by RAPTOR + mTOR trigger full kinase activity.👉 The membrane is not just a platform — it’s part of the mechanism. www.nature.com/articles/s41...

Excited to see work led by @autophazeke.bsky.social, @minghaochen.bsky.social, Thanh Nguyen, and Ainara Claveras out in @science.org today, the culmination of a 15-year project to understand structurally how the synthesis of the critical lipid of autophagy, PI3P, is regulated. tinyurl.com/ywvjh8u4
Our new FASEBJ paper. We looked into mTOR Ser1261 phosphorylation in human and mouse muscle, proposed by Diane Fingar's lab to be first an Akt and then AMPK site regulating mTORC1 and 2 activity. Clearly AMPK site but impact on mTORC unclear in our hands faseb.onlinelibrary.wiley.com/doi/10.1096/...
mTOR Ser1261 is an AMPK‐dependent phosphosite in mouse and human skeletal muscle not required for mTORC2 activity

Unsolicited writing advice, no #7262: When you're editing a project, try changing the font before you start. It tricks your brain into seeing your words anew, making it easier to spot typos or areas that might need work.

Every year, I give my lab (and myself) a "mini-sabbatical" to pursue creative endeavors outside of regular work/studies. So I spent some time reflecting on my thoughts on #AI + the role of professors in this AI transformation via a short film 📽️: www.youtube.com/watch?v=6MPs... #AcademicSky

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.
