Enviable discipline in the @kevin-dean.bsky.social lab:
While Kevin is far away discussing the future of microscopy, his lab meeting is carried out independently.
I snapped the first slide for illustration of the seriousness of the business discussed (suppl. Figure 2: zoom-in).

The #mesoSPIM community just celebrated 10 years of open-source light-sheet microscopy in Zürich! For #3DThursday, we're honoring Martina Schaettin & Fabian Voigt’s iconic 3D chick embryo dataset — a luminous benchmark for open science and shared discovery.

This semester I am teaching in a course called Mathematical Foundations of Quantitative Biology.
It involves combinatorics, distributions, calculus (ODEs and PDEs), linear algebra and Fourier Series and Transforms.
Taught on blackboard with chalk.
Actually quite excited to do some #math .

Thrilled to announce the launch of my lab
@cri-utsw.bsky.social at UTSW this January!
We will explore how cells sense and respond to mechanical forces, focusing on membrane mechanics to reveal how tension and signaling work together to shape cell behavior.

We're growing! Our newest Investigator @henrydebelly.bsky.social will join the CRI Tissue #Regeneration Program in January 2026. Learn more about Henry ➡️ cri.utsw.edu/faculty/henr... and 📌apply to research in his lab cri.utsw.edu/careers

I have now received an official NIH email that the study section tomorrow is off😞.
I have a study section scheduled this week. Any chance it will take place?
SRO has not replied for days. Submitted 7 critiques on time nevertheless.
