Hello Bluesky! I lead a lab at UNC that uses microscopy approaches to study organelle dynamics, lipid trafficking, and neurodegenerative disease.
Ithaca is gorge-ous! Thank you @fromme-lab.bsky.social, @jeremybaskin.bsky.social and colleagues for a very fun and stimulating visit to the Weill Institute for Cell and Molecular Biology at Cornell!

It’s clear we need alternatives or at least ways to improve the situation. So, together with a really special and talented team we worked to develop this idea into “qed” a platform where you can get CONSTRUCTIVE feedback on your own work or CRITICALLY assess other people’s papers.

Genuinely thrilled to share our new story with the world - an amazing collaboration with @profsharona.bsky.social and Bill Zagotta using their innovative FRET technique to study mitofusin conformational changes. Huge credit to Sophie Hurwitz for tackling this project. urldefense.com/v3/__https:/...
Structural insights into GTP-coupled conformational changes in Mfn1 revealed by time-resolved transition metal ion FRET.
Outer mitochondrial membrane fusion is mediated by the mitofusin paralogs Mfn1 and Mfn2. Nucleotide-driven self-assembly and conformational changes are required for regulated membrane fusion activity,...
