📢Job alert📢 @uniheidelberg.bsky.social has an opening for a full W3-position on “Modeling of Biological Processes” 😀👍 Here is the call tinyurl.com/3w9e9dtf and application deadline is March 15. The group would be located at the beautiful #BioQuant center right in the middle of Neuenheimer Feld.

This made me happy this morning: USB powered laser diode with decent beam profile. On demand collimated beams of different sizes. Little ups while most things look pretty bleak.

Cell, Nature and Science may have high impact factors, but @optica.org has its own aircraft😎. cc @ceej64.bsky.social

Integrated in an imaging system with a 60X NA 1.49 lens. Pretty clean rotation near optical axis.

PhD position in my lab!

I'll be part of a very illustrious seminar series at Duke BME later this year! bme.duke.edu/news/disting... Thanks to Junjie Yao and my other hosts!

90° Galvanometric image rotator. A bit harder to do than expected, but I’m also getting rusty. Also need to tighten everything…

Daycare closed, so Naomi did some hyperspectral single molecule localization microscopy at home. She figured out the Cramér-Rao lower bound all by herself. #parenting

We have two funded postdoctoral positions available. Topics encompass: -Next gen light-sheet fluorescence microscopy instrumentation -Structured illumination microscopy and other approaches to extend the resolution limit. -Nonlinear microscopy combined with adaptive optics / phase conjugation

To be fair, north Texas is pretty flat…😅

A little colder today here in North Texas.

#history In the Soviet Union, there were different levels of “news” (referred to as red and white TASS). The public received the highly redacted version that left out internal disasters and some world events. Party officials got the actual world news as classified information.

We lost a giant in public health today. Dr. William H. Foege helped eradicate #smallpox - the only human disease ever eliminated—through science, surveillance, and vaccines. His legacy is the antidote to today’s antiscience, anti-vaccine rhetoric. www.nytimes.com/2026/01/24/u...

A summer stroll for our dog… How is everyone else holding up?

So excited to share the preprint with the bulk of my PhD work in the Beach @myosincity.bsky.social and Oakes @pwoakes.bsky.social Labs at Loyola University Chicago! We investigate the structure, recruitment, and function of septin networks around the nucleus. A thread: doi.org/10.64898/202...

We started the farewelk proceedings for @bingyingchen.bsky.social which included a climbing outing (Bingying is an expert climber). That was a lot of fun. I was toast after climbing three bunny walls (Figure 1). Bingying showed us some “free solo” level climbs. Impressive.

I’m looking forward to the weekend in DFW…

🚨 We are hiring TWO postdocs to join the Cell Migration Lab (cellmig.org) 🇫🇮 as part of the new Centre of Excellence in Immune–Endothelial Interfaces (IMMENs). Join us to decode immune regulation & develop next-gen imaging tools! 🧪🔬 Details in thread 🧵👇 #ScienceSky #Postdoc #AcademicJobs Please RT🫶

Job 1: Postdoc in Bioimaging 🖥️🔬 We are looking for a method developer at the interface of Bioimaging, microscopy, deep learning, and image analysis. Ideally, you love Biological images, Python 🐍, open-source software, and "smart" microscopy. Apply here: abo.rekrytointi.com/paikat/index...

Me at Photonics West talking about Machine Learning AO wavefront sensor… @spie.org

RIP Gladys West, mathematician who measured the world to unheard precision (radius to tens of centimeters!), paving the way to GPS.

It is not good coverage, but the few trains in the US can be pretty good if you can make your trip work. Also dirt cheap. DART costs me an order of magnitude less than an UBER ($3 vs $50). (CalTrain and DART Silver line pictured)

Apply for the Postdoc Programme of the Health & Life Science Alliance in Heidelberg and Mannheim. Do an interinstitutional, interdisciplinary between 2 of 7 partner institutes, including EMBL, the University, DKFZ. www.health-life-sciences.de/postdocs/ Deadline: 31 March

Asked for Cadper kdrl-egfp zebrafish, but they did not have it🙁. #overmarketing @zebrafishrock.bsky.social

@spie.org Great day at Photonics West!

That was a fun ride.

Seen in San Francisco: Zoox self driving car. Experimental operation mode.

Europe’s first sodium-ion cell made with fully domestic components www.pv-magazine.com/2025/12/18/e...

That display is pretty cool, @spie.org ! I remember some years ago, it was “just” some galvo mirror laser show at the north entrance.

Photonics West about to start. Right where Apple gives their keynote talks. No pressure…😀

Golden hour…

Exciting postdoc opportunity with Dr Laura Clark focused on the theory side of 4D-STEM/ptychography for anyone interested in underlying optics, deadline 29th January 2026. Informal discussions welcome. Read more here: jobs.york.ac.uk/vacancy/pdra...

…Oz went on to say that there was "never really good" data to back up that men should only have two alcoholic beverages per day and women should only have one. Alcohol is a known carcinogen, and plenty of other health issues are linked to alcoholism… www.newsweek.com/alcohol-new-...

Is improving your microscopy skills one of your 2026 resolutions? Should it be? Apply to an excellent course that will get you up to (light) speed! Analytical and Quantitative Light Microscopy at the MBL is accepting applications. @mblscience.bsky.social @aqlm.bsky.social

This will not last long… Happy to take lifetime estimates.

Good morning.

The cryo cyclical multiplexing expansion microscopy (Cy-ExM) preprint from @seweryn-galecki.bsky.social , @kevin-dean.bsky.social et al is online. 20 targets across an entire cell. Mr. Snouty also joined the fun. www.biorxiv.org/content/10.6...

20-plex volumetric super-resolution imaging of cellular ultrastructure. Preprint, led by @seweryn-galecki.bsky.social, dropping soon.

Is this how it works? #law

How the morning walk with the dog felt this morning. Yesterday was shorts and T-shirt weather. #Dallas

Currently grading the exams of our grand tour of math lecture (combinatorics, complex number, linear algebra, Transforms, ODEs and PDEs). Very happy to see that the students did exceptionally well! Damn skippy, someone even solved the i^i spicy question.

Schrödinger chocolate: delicious and inedible at the same time😳😅.

Honored to lecture at AQLM. Yes, I was a student in the class of 2007, a fantastic course!
