Excited to share that I will start my lab at the Center for Integrative Genomics in Lausanne @unil.bsky.social in Jan 2027! I’m looking for PhD students fascinated by how cells build tissues and excited about developing new technologies to study development across scales. www.wanlab.bio/pages/9397

#DBfeature Elongation of the nascent avian foregut requires coordination of intrinsic and extrinsic cell behaviors By Olivia Powell, Emily Garcia, Vanshika Sriram, Yi Qu, Nandan L. Nerurkar tinyurl.com/52pecyc5

Endodermal tissue deformations at the AIP during foregut elongation. (A) Velocity fields quantified from time lapse of cell movements between HH stages 8+ and 10+. Orientation and magnitude of arrows indicate orientation and speed of cell movements, respectively; underlying heat map indicates speed (n = 3); scale = 200 μm. (B) Principal strain rates computed from velocity fields in (A), where major and minor cruciform axes represent maximum and minimum principal strain rates D1 and D2, respectively, and their orientations represent the associated principal directions. Negative/compressive principal strain rates are indicated in blue, and positive/extensional strain rates are indicated in red; strain rate scale = 0.01 %/s; spatial scale is as in (A). (C) Maximum and minimum principal strain rates calculated from velocity fields at HH stage 8, following electroporation with 3 nls-GFP RNA control (left) and DeAct-GFP RNA (right) (n = 3);

1/ 🔬🧑‍💻 Tired of going back and forth between GUIs and code for your 3D image analysis needs? Would you like to keep your focus in one place (notebook), without sacrificing interactivity? Here’s a tool that can help!

Yep, it lags a little. But still quite impressive considering that each "pixel" is a 150 MPixel multires image. Overall the total number of 'adressable' pixels in this 2D image are 225x225x150 Mpix = 7.6 Tera pixels. #ImageJ #Fiji #BigDataViewer

1/ 🐣⚒️ To study mechanics, we need to apply prescribed forces - how can we do that in living tissues? I am @eigenp.bsky.social and in this thread I'll highlight our new approach for applying tension on epithelial tissues in vivo!

New preprint from my PhD in @amphispacelab.bsky.social is out! 🥳 We investigated the evolution of my favorite gene FoxQ2 across 21 animal phyla, and found three ancient paralogs with a very dynamic history. More on phylogeny, synteny, and comparative in situs in the 🧵 below! tinyurl.com/2j96px45

Evolutionary dynamics of FoxQ2 transcription factors across metazoans: A tale of three ancient paralogs

FoxQ2 is a highly conserved class of Forkhead-box transcription factors expressed on the anterior side of the body in cnidarians and bilaterians. Despite this conserved expression pattern, recent phyl...

For my first post on 🦋, I am incredibly excited to share that my PhD paper has been published in #ScienceAdvances! We compared the development of the anterior neuroectoderm to uncover how the chordate #forebrain evolved 🧠. Have a look at the summary 🧵 below! www.science.org/doi/10.1126/...
