Congratulations, Charles!

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. 🤩

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! 🧪🏔️

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.

Structural basis for mTORC1 activation on the lysosomal membrane - Nature Cryo-electron microscopy was used to study human mechanistic target of rapamycin complex 1 (mTORC1) activation on lysosomal membranes, showing progressive recruitment by RAG–Ragulator, RHEB and R...

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.

Extremely excited to share that I’m joining Columbia University @columbiauniversity.bsky.social as an Assistant Professor!

We will explore how the mobile genome works—how transposons shape us, our DNA and how they can be harnessed to build useful technologies. #NewPI #RNAsky #TEsky

Thx to Andreas, Hammad, Dmitry, Gerhard @laynefrechette.bsky.social and everybody else who contributed!

There are days in life that shake you.

I’m shattered 💔 to share that I just found out that the US Government terminated my 2024 NIH Director’s Early Independence Award (~$2 million), threatening my long-promised assistant professor job at Columbia University

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

mTOR Ser1261 is an AMPK‐dependent phosphosite in mouse and human skeletal muscle not required for mTORC2 activity mTOR Ser1261 is an AMPK-dependent phosphosite in human and mouse skeletal muscle that responds to exercise but not insulin, plays an unclear role in mTORC1 regulation, and is not required for mTORC2 ....

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/...

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.

Wow. This is the first neat paper of 2025! From a baby plate of HEK cells and a uL column

in the midst of an AI transformation | a short film YouTube video by Prof. Jean Fan

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.

Check out the latest Discover ASAP episode with @doroteaartscience.bsky.social, a member of CRN Team Hurley, who is making science beautiful and accessible. From mitophagy to #PD research, her work shows how #OpenScience thrives with clear, creative communication.
