Amazing to have this come online on the day of my viva - will hopefully be able to celebrate the success of both (fingers crossed) by the end of the day!! 😅 🤞 🥳

Please check out our new review in Biochemistry @ACSPublications on aspartimides in RiPPs, led by Angela Zhu: doi.org/10.1021/acs.bi…. Happy to be part of the special issue on the chemistry and biology of peptides!

Excited to share my 1st first name paper from 🐅 @ajlinklab We report the ability to rearrange #RiPP precursor peptides, expanding opportunities for engineering PTMs in vitro and in cellulo including mechanically interlocked peptides 🔗 @LindemannTrust @omenndarlingbio

Applications for our postdoc fellowships are due on Jan 31. Learn more and apply here: bioengineering.princeton.edu/join/open

It's that time of year again - @cenmag Molecule of the Year! There are some fascinating molecules in there so vote for your favourite. We aren't biased of course, but there's a cool-looking cyclo[48]carbon catenane in there... cen.acs.org/sections/moty-…

We are seeking our third cohort of BioE Ph.D. students! Applications due by the end of the month for Fall 2026 admission. Learn more: bioengineering.princeton.edu/graduate?utm_s…

Come work with us! We have a PhD opportunity available with Hess and Giuliani groups. Please reach out if you are interested. @Jeannine__Hess @CRUKCOLcentre colcc.ac.uk/2026-phd-proje…

Excited to speak at Princeton Bioengineering this Thursday, October 9. bioengineering.princeton.edu/events/2025/re…

@VivesGui @Chem_CP @enxu_liu Great to see this out in print 🥳

Our work on the unidirectional motion of a CD is now in the September issue of Chem and on the cover! Many thanks to the whole team and @Chem_CP for the highlight! @enxu_liu cell.com/chem/fulltext/…

A promiscuous #rSAM enzyme achieves diverse peptide cross links at non-canonical residue sites. @taikade (Eastman) @agr_chemistry (Roberts) @vahooster (Bandarian) @utahchemistry @uutah @pnasnews pnas.org/doi/full/10.10…

Put a cyclocarbon in a vial! After more than a decade endeavour in the Harry’s group,⁦@HLAGroupOx⁩ finally, we made it happen. phys.org/news/2025-08-c…

⭕ Synthesising a new carbon allotrope Amazing work from @HLAGroupOx, published this week in @ScienceMagazine: a cyclocarbon that is stable enough for spectroscopic characterisation in solution at room temperature. Read more: chem.ox.ac.uk/article/synthe…

Another paper that was supposed to be quick, but ended up taking 4 years. Bringing high throughput screening and machine learning to the field of synthetic anion transporters... pubs.rsc.org/en/Content/Art…

Introducing the bionic azobenzene cell, AKA "Photocell", capable of modulating the viscosity of its internal membrane systems with light. I am still amazed how many photolipids cells can gobble up and accommodate. A wonderful collaboration with Howard Riezman, Suihan Feng, @mo_hannes and @NoemiJRojo. pubs.acs.org/doi/full/10.10…
