Fletcher Lab
@FletcherLab_UCB
The Fletcher lab @UCBerkeley in the @BerkeleyBioE, @UCB_Biophysics, @BerkeleyMCB departments. Account run by students/post-docs.
Lab: Why aren't we on Twitter? Dan: Umm. I don't follow Twitter. Lab: But the rest of the world does. Scientists too. Dan: I see. What's your point? Lab: We should be on Twitter. And join scientific discussions. Dan: I'm more the silent type. Lab: We'll run it. Dan: Go for it!
🌟Say hello to Dan Fletcher @FletcherLab_UCB, a bioengineer renowned for developing novel experimental approaches and microscopy tools with far-reaching impacts on our understanding of infectious diseases, immunology, and cancer biology. 1/
Happy Lunar New Year! We hope the Lunar New Year brings you much health and happiness. #HappyLunarNewYear2025
Had fun at the MBL Physiology Course in Woods Hole. Chunzi, Elizabeth & Kira led creative rotations: • Trogocytosis is a mi(gh)t-y way to transfer • Sync(ytium) or Swim: Which fusogen will reign supreme? • Mucin Impossible: Eat up or get lost

Welcome to our new BioE Ph.D. students, Smiti and Michael Anne! @smiti_m

Congratulations Caitlin (@CaitlinCornell6)!!
Congratulations to the eight recipients of the 2025 Dr. Eddie Méndez Scholar Award! This award recognizes outstanding early-career scientists from underrepresented backgrounds who are studying cancer, infectious diseases and basic sciences. Learn more: bit.ly/4jWvT8O
Come to the Annual Fletcher Lab Artshow on Friday May 9th, 2025! We host this event as an opportunity for folks to display their artwork, come together with wine and cheese, and admire artwork!

Come explore and be amazed on April 12 and 13 at the @exploratorium. This event is based upon work supported by the @c3STC #microscopy #Magnified

Congratulations to both Jared and Andres (@adextre521) for passing their qualifying exams


preLights in cell biology (Feb 2025) This article lists the recent @preLights posts that discuss #preprints in #cellbio. Featured #preLight by Felipe Del Valle Batalla @coffee_lipe covering work on macrophage trogocytosis from @FletcherLab_UCB. journals.biologists.com/jcs/article/13…
Some lab members and friends attended the #StandUpForScience protest


I’m excited to visit @UCBerkeley this fall as a Visiting Miller Professor. Looking forward to soaking up the great science and good vibes with @FletcherLab_UCB @optrickster @Yildiz_Lab Sam Lewis lab Ke Xu lab and >>. Thanks, @UCB_MillerInst 💚
The Miller Institute is proud to announce the awards for Visiting Miller Professorship terms during the 2025-2026 Academic Year. The Visiting Miller Professors join faculty hosts on the Berkeley campus for collaborative research interactions. bit.ly/48IWy3V #science
“We have a role to play in making the world a better place.” Thank you to Dan Fletcher @FletcherLab_UCB for hosting and @UCBerkeley faculty for compelling sessions on navigating a path in research and entrepreneurship, part of the Science Leadership Program for our 2024 Fellows
Cell surface crowding is a tunable biophysical barrier to cell-cell fusion biorxiv.org/content/10.110…
Check out our latest preprint where we show how you can improve automated detection of schistosomiasis by using images of multiple contrasts (brightfield and darkfield) acquired on a mobile microscope! medrxiv.org/content/10.110…

Attention students and postdocs - apply for the MBL Physiology course and come find out why so many Physiology students describe the course as life-changing!!! mbl.edu/education/adva…
Check out our most recent paper about a previously under-appreciated crowding barrier to cell-cell fusion. biorxiv.org/content/10.110…
Check out this exciting @preLights on one of our recent papers. Felipe (@coffee_lipe) did a fantastic job summarizing the main points and asking intriguing questions for our future next steps.
Happy to share my newest contribution to @preLights “Target cell tension regulates trogocytosis” prelights.biologists.com/highlights/tar…
Happy New Year! Let’s continue pushing the boundaries of science and knowledge #HappyNewYear2025
