Super happy to announce that in October I will be joining the University of Warwick as an assistant professor! We will be continuing to examine the molecular mechanisms of intracellular trafficking using a range of samples, including plants and diatoms ⚽️🌱🔬

Less than one week to go! We're excited to hear talks from @laurabacete.bsky.social and @sventruckenbrodt.bsky.social. Join us online on Thursday 16 July at 15:00 BST.

This session will showcase some really state-of-the-art imaging techniques to look at cellular architecture (@sventruckenbrodt.bsky.social) and live, contact free biomechanics (@laurabacete.bsky.social)! Sign up below! #expansionmicroscopy #brillouin #plants 🌱🔬

🔬🌱Register now for the second webinar in our new series on quantitative plant imaging. We’ll be hearing about using Brillouin microscopy to measure plant cell wall mechanics from @laurabacete.bsky.social, while @sventruckenbrodt.bsky.social will introduce PlantEx. 🗓️16 July at 15:00 BST

Also in our list, we highlight a preprint on Phasor-based analysis for multiplex imaging in plants from Beatrice Lace @blace.bsky.social & Thomas Ott @ottlab.bsky.social. You can learn more in our 1st webinar in our quantitative plant imaging series: focalplane.biologists.com/2026/05/19/f...

We’re excited to hear from Alex Johnson of the University of Exeter! 🎉 Alex investigates clathrin-mediated endocytosis in plants and algae, highlighting how photosynthetic organisms sense and respond to their environment through mechanisms that differ from those in mammalian or yeast systems.

Come join us online on July 16 to learn about PlantEx — using expansion microscopy to image plants at 20–60 nm resolution, and in multi-colour no less! ☘️🌈🔬

🌱🔬Save the date for the second webinar in this series: Thursday 16 July at 15:00 BST. Updates will appear on our webpage or you can sign up to our FocalPlane features... mailing list to stay up-to-date with the latest information. focalplane.biologists.com/macro-to-mic...

If you ever wondered about the history and current state of plant Clathrin-mediated endocytosis....here is a review just for you! onlinelibrary.wiley.com/doi/10.1111/... Was really fun to write this with awesome co-authors! ⚽️🌱🔬

There is still time to register for @focalplane.bsky.social's inaugural plant imaging webinar tomorrow. #plantimaging focalplane.biologists.com/2026/03/30/n...

📢 Two weeks to go until the first webinar in our new series on quantitative plant imaging across scales. We’ll hear from @blace.bsky.social and Simon Gilroy in this webinar chaired by @ajcellbio.bsky.social and @joemckenna.bsky.social.

Thanks for this initiative! Great idea. Happy to see @blace.bsky.social from our lab @biologyunifreiburg.bsky.social and involved in imaging approaches @sfb1381.bsky.social kicks it off. Hope to see many people online.

We are excited to launch a new webinar series, Macro to micro: quantitative plant imaging across scales, organised by @ajcellbio.bsky.social and @joemckenna.bsky.social. Our first webinar will featured talks from @blace.bsky.social and Simon Gilroy. focalplane.biologists.com/2026/03/30/n...

🌱🔬If you’re a plant biologist using imaging in your research, check back with us on Monday for an exciting announcement! @ajcellbio.bsky.social @joemckenna.bsky.social #teaser #plantbiology #microscopy

In the frame of the French ANR funded project HOMONIME project (anr.fr/Projet-ANR-2...), we will open 3 PhD positions to work on nickel homeostasis in plants using genomic, proteomic, metabolomic and spectrometric approches in Toulouse, Grenoble and Pau. Contact me for further informations

Abstract deadline extended until March 20th! Come talk about plants and microscopy! #imc21 🌱🔬

A big thanks to Alex, Joe, Marketa, Mark and @biologists.bsky.social for bringing together plant imaging enthusiasts across scales and career stages - all in a classic English countryside setting!🔬🌱 @ajcellbio.bsky.social @joemckenna.bsky.social @focalplane.bsky.social

A huge thank you to Joe, Alex, Marketa, Mark and @biologists.bsky.social for bringing together an absolutely amazing community in plant imaging 🌱🔬 in the stunning Sussex countryside.

⚡️Funded PhD position in my lab in Exeter 🧠 @exeter.ac.uk If you are interested in brain development, cell-type diversity, neuroglia, subcortical structures and neurodevelopmental disorders, check out this opportunity. Deadline 28 Feb. Please RT🙏. www.exeter.ac.uk/study/fundin...

Post-lunch, @ajcellbio.bsky.social telling us about imaging plant endocytosis using multiple techniques 🔬

We’re excited to announce our special guest speaker for Flora in Focus: A Microscopy Conference for Plant Scientists Join us as Dr Alex Johnson, Research Fellow at University of Exeter, presents “Probing plant endocytosis at multiple scales.”

The final version of our multispectral microscopy manuscript is now online at Nature Photonics: www.nature.com/articles/s41... The main additions are some further comparisons to yet more unmixing algorithms, in which we find that our algorithm is still the most accurate.

Deadline for funded places has been extended to the 5th of September! So if your a PhD, post doc, newish PI and like imaging plants - this is a great chance to hang out and talk with some experts in a fancy English countryside house 🌱🔬😎

Organised by Alex Johnson and Joe McKenna, who we have had the pleasure of working with at the Gatsby Plant Science Summer School, this is a great opportunity not to be missed! Just 2 more days to apply for a funded place if you are an ECR

How does evolution shape ancient cellular processes? Our new paper uncovers the mosaic evolution of conserved and diverging endocytic traits in fungi! www.cell.com/current-biol...

Interested in imaging plants, then this is a great workshop for you! We have a great line up of speakers from plant and ‘outside’ fields, fantastic location and spaces for ECRs to come and join in the fun! 🌱🔬💻🤓

Super happy for 1st author Michelle this is out! It was fun to help out and try some new ways of imaging. 🌱🔬 #plantsarepretty
