Had an absolutely fantastic time at the @faseborg.bsky.social #Phospholipids in Aging and Disease meeting in Scottsdale, AZ this past week! I had the honour of presenting my recent work, with the added bonus of bringing home the @jcellsci.bsky.social Best Poster Award.

Thrilled to share this #lipidtime mechanism story in @jcb.org where, led by Shiying Huang and in collaboration with Tamas Balla’s lab, we uncover plasticity in phospholipid metabolism to preserve plasma membrane identity and integrity in the face of disease-relevant perturbations!

i also 'store' pdfs in the downloads folder, but that's actually a bit misleading because when i need a pdf, i do not retrieve it from the downloads folder, where it may well be stored. i just go back to the internet and download it again

Beautiful desert views. Beautiful membrane biology. Join us for the #FASEB Phospholipids in Aging and Disease SRC in Arizona, July 26–30 2026. Registration is now open! So much better than a Lipid Droplets conference. Also, we're co-located with FASEB Lipid Droplets 😜

Thrilled to share our latest study, led by @reikatei.bsky.social, in @natchembio.nature.com! We began by asking a simple question—how do cells know if they have too much of a lipid in a particular membrane, and how do they respond to rectify this imbalance? www.nature.com/articles/s41...

Great collaborative work where we developed a nanobody based tool to block EFR3 mediated recruitment of PI4KA. A potential therapeutic window maybe? Thanks @alexlouiseshaw.bsky.social for the assist!

New preprint from the lab headed up by @sushantsuresh.bsky.social! Late last year, we published the molecular basis of PI4KA plasma membrane recruitment by EFR3 (PMID:39705356). This work builds on these findings and identifies a new potential therapeutic avenue! Check it out!
