The 2026 Visual System Development GRC and GRS are fast approaching. Jeremy Kay, Kristen Kwan, Robert Johnston, and I have built an exciting program that we hope you will enjoy. Looking forward to seeing everyone at the meeting this summer in beautiful Maine. Register and RT!

Excited to share our new manuscript from the Yoshimatsu and MacDonald labs. biorxiv.org/content/10.648…. We found that my favourite glial cells can regulate local retinoic acid signalling to specialise cone photoreceptors for high acuity vision.

Latest from the lab. Beautiful work from Joanna Lau and a fantastic collaboration with James Fitzgerald. cell.com/current-biolog…

Last few days to apply to come work with our team- deadline 11th April. See details below.

We have a 3 year postdoc position using the killifish to study retinal ageing available in my lab. Based in London, UK and visa eligible. We’re interested in glial mechanisms underpinning age-related neurodegeneration. If you, or someone you know, is interested please reach out.

We are seeking a Postdoctoral Fellow to join the @MacDonald_Lab to lead a project investigating how genetic dysregulation in glial cells potentially drives neurodegeneration in retinal ageing. Position closes next week: 25 February. More details: ucl.ac.uk/work-at-ucl/se…

We’re hiring a new research fellow. Come join us in London to study glial cells in the ageing retina using killifish as a model. ucl.ac.uk/work-at-ucl/se…

Do you have #iPSCs culture and differentiation skills and want to combine this with in vivo #zebrafish model, live imaging, -omics and a fun environment? Please apply to our 3-year MRC funded PDRA post at @BiologyatYork @YBRI_UoY jobs.york.ac.uk/vacancy/resear…

Join us for your #PhD in fully funded @The_MRC studentship to work in my lab @dev_neuro @KingsCollegeLon together with @dimvladkost on Experience-dependent plasticity in the zebrafish brain. Check out @KCL_MRCDTP catalogue NS-MH2025_16 #MRCDTP25

Boost your immunofluorescence (IF) techniques in zebrafish retinae! 🐟 @NJaroszynska from @MacDonald_Lab at @UCLeye shares a comprehensive review of IF steps, with tips for any tissue, in this @Proteintech blog. Check it out: bit.ly/479XKO4

Congratulations @NJaroszynska! Very proud of my first PhD student for all the hard work! She did an amazing job pushing our understanding of Muller glia and the ECM forward. Look out for the paper soon.

I’m ofFISHially a doctor! 🎓🐟🧬👁️ Thank you to my supervisor @MacDonald_Lab, the lovely examiners and my amazing lab members for making this day so special! @UCLeye it’s been a pleasure to work here all these years!
