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!

Reminded me of my own PhD graduation in 2011. Here I am with my PhD advisor, Dr. Nelly Pante.

So fun to hood Dr. Shannon Rhoads at the UNC Doctoral Hooding Ceremony today! I got to bust out my U British Columbia regalia…

Heading to #CellBio2024? Do you love #lipids? Join us for an exciting subgroup on Lipids in Organelle Form and Function, Saturday at 1:45 PM! Lipid-themed happy hour to follow but you must attend the session to find out the location!

Because the green and red monomers both dimerize with the B monomer, Contact-FP can also be used to visualize 2 contact sites that share an organelle, e.g., ER-LD and LD-mitochondria 9/11

Contact-FP can be used to visualize dynamic interactions between any organelle pair represented in the toolkit – shown here for LD-mitochondria. 8/11

We engineered a suite of ddFPS (red, green, and B monomers) targeted to 8 compartments: cytoplasm #LipidDroplet #ER #Mitochondria #Peroxisomes #PlasmaMembrane #Caveolae and #Lysosome. 5/11

We turned to a palette of dimerization-dependent fluorescent proteins (ddFPS) developed by Robert Campbell’s group. ddFPs consist of two weakly fluorescent monomeric proteins that reversibly interact to form a fluorescent heterodimeric complex. 4/11

Membrane contact sites allow cells to channel ions and lipids between compartments. We know from previous work that membrane contact sites are very dynamic. These images show lipid droplets transiently interacting with up to 5 other organelle types over a 5-minute period. 2/11

Chapel Hill folks, if you have not already seen it, I highly recommend Paperhand Puppet Intervention’s “Where the Spirits Reside”…this was the medicine my spirit needed this weekend

Hello Bluesky! I lead a lab at UNC that uses microscopy approaches to study organelle dynamics, lipid trafficking, and neurodegenerative disease.
