As I'm updating my NIH Biosketch for the N-th time this year, I made a Jekyll theme for students to familiarize themselves with this CV structure while building their online presence. Demo: jefworks.github.io/online-biosk... Fork to modify: github.com/JEFworks/onl... #JustAcademicThings

I never got good at CSS box model (parent-child dynamics, relative/absolute/fixed positions, etc). Vibe coding let me mentally offload those mechanics to refocus on creative design. Made this to showcase my photos of vintage cameras/microscopes/slides. Check it out: microspeci.men

Thanks to the authors for sharing all components of this beautiful mouse embryo spatial transcriptomics data from cell gene counts to per-molecule coordinates: www.ahajournals.org/doi/full/10.... So I vibe coded an app to explore the 3D subcellular transcript organization: jef.works/CellCarto-Mo...

I've seen some cool gesture-based point cloud controllers. So I noted the JS libraries used and vibe coded a similar web app to explore the relationship between spatial, UMAP, and PCA embeddings for spatial transcriptomics data. Next level interactivity via 🖐️ Try it out: jef.works/GestureGraph/

As a younger prof, I'm seeing generational divides in academia w/ senior colleagues (late 1900s) resisting metrification/audit culture vs. those of us raised in it. So I had fun writing a reflection on "University Professors in the Neoliberal Academic Ecosystem": jean.fan/2026/01/12/n...

Newfound disappointment: receiving shallow peer reviews that are entirely AI-generated. The whole point is critical feedback from YOU as a real expert. If reviewers are outsourcing to AI, I think we've lost the plot 🤷‍♀️ As an editor, I'm definitely keeping better track of reviewers I can trust...

When polishing scientific figures for publication, I try to limit fonts and font sizes to reduce visual noise. But doing this by hand is very tedious. So I vibe coded a small web app to standardize text in SVGs: jef.works/SVG-Text-Sta... Try it out! Hope it’s useful!

I tried to vibe code music in TidalCycles on strudel.cc but got hallucinated garbage (maybe TidalCycles is not well represented in the training data) So I read the documentation and manually coded this cover of Teardrop by Massive Attack: youtube.com/shorts/CnH51... #FunWithCode

The authors did such a great job making this spatial transcriptomics data of ovulating mouse ovaries available: www.pnas.org/doi/10.1073/... So I vibe coded a web browser app to interactively explore its spatiotemporal gene expression trends: jef.works/CellCarto-Ov... Hope it's useful!

Every year, I give my lab (+myself) a "mini-sabbatical" to pursue independent learning. This year, I'm learning to use AI tools. So I made a short film to reflect on life/death + create art in an era where it can feel like AI has usurped the value of self-expression: youtu.be/YJjmKRlmI1Q

Check out our new preprint on STARIT for creating image-based tensor representations of molecular resolution spatial transcriptomics data that can be combined with deep learning computer vision models to recover cell-states based on subcellular heterogeneity: www.biorxiv.org/content/10.6... 🧵👇

In this journal club commentary, I reflect on an older paper from the Campbell group @sangerinstitute.bsky.social showing how normal skin is full cancer mutations yet stays healthy to highlight the opportunity to revisit this question using new spatial omics tech: www.nature.com/articles/s41...

What is RNA velocity in situ? ChatGPT kept getting it wrong... So I made this video explaining how RNA velocity in situ infers gene expression dynamics by distinguishing nuclear vs. cytoplasmic expression in spatial transcriptomics data: youtu.be/z9Oxf1hvum0 #AcademicSky

Looking to prep for faculty job interviews? Try my Academic Interview Simulator: Faculty Edition. About as realistic as dating sims are to real dating 🤣: www.youtube.com/watch?v=dzv-... (I'm tinkering w/ AI. Inspired by the Rising Stars workshop for post-docs I just served on. Real advice 👇)

In this blog post, I use #RStats to explore publicly available ICE arrest data. #Dataviz shows recent trend where ICE are primarily targeting/locating people without criminal records in communities. Code along and take a look for yourself: jef.works/blog/2025/09... #CodeTutorial

Wrapping up AI in Molecular Biology, we celebrate 3 Future of Science Fund Award winners: @ryantheshark.bsky.social (@ucberkeleyofficial.bsky.social), Lucy Luo (@nufeinbergmed.bsky.social) & Reet Mishra. Their work shows the bright future of science! 🌟 #KSAIBio26 @drkbio.bsky.social @jef.works

High costs motivate efforts to predict spatial transcriptomics from H&E images w/ deep learning. In our recent preprint, we show that noise, sparsity & resolution in ST data impact performance, highlighting the importance of training data quality: www.biorxiv.org/content/10.1... 🧵1/n

Our paper identifying evidence of off-target probe binding in the 10x Genomics Xenium Breast Gene Panel is now available as a reviewed preprint at #eLife elifesciences.org/reviewed-pre... We look forward to revising the paper to incorporate reviewer recommendations and other updates 🧵👇

Final call for posters @keystonesymposia.bsky.social on AI in molecular biology. Deadline August 21 Beyond talks, our program also includes panel discussions on challenges + opportunities for innovation + responsibility in AI-driven biology: keysym.us/KSAIBio26 Hope u can join the conversation!

In this interview, I explain how university research, when funded by independent #NIH #NSF federal grants, brings oversight to biotech to fuel innovation while keeping science transparent, reliable, and in service of the public good: hub.jhu.edu/2025/07/30/j... #ResearchMatters

People are being arrested by ICE. What countries are they from? I analyze public data from deportationdata.org/data/ice.html to find increased arrests for immigrants from many countries #FirstTheyCame Code so you can reproduce these trends for yourself: gist.github.com/JEFworks/1f0...

I visualize trends in #ICE #immigration arrests and encounters over time and across select US cities using public data from deportationdata.org/data/ice.html Here is the #RStats #ggplot code so you can visualize the #dataviz trends in your own city: gist.github.com/JEFworks/0c7... #codetutorial

I received some old microscopy slides from the 1800s, when at-home microscopes made it possible to look at hidden worlds of diatoms, polycystina, and other teeny tiny things. I made this website so people today can take a look too: microspeci.men Enjoy! #scienceisforeveryone #microscopy #HistSci

I use #ggplot #gganimate #Rstats to visualize spatiotemporal trends in public ICE detention data. Watch ICE detention increase over time: more detainees (bigger dots), more non-criminals (blue → red), and more jails far from the border in 2025. Code #gist: gist.github.com/JEFworks/899... #DataViz

In this blog post, I use #RStats to analyze ICE detention data. #Datavisualization shows record numbers of detainees without any criminal records. Further more/bigger ICE facilities are popping up far from the border. Code along and take a look for yourself: jef.works/blog/2025/07... #CodeTutorial

How it started vs. How it's going #Tenured Grateful to all those who've been a part of this journey so far. But the fun is just getting started 💪 Curious to find out just what this privilege of tenure can enable. Let's see how we can put it to the test. Feel free to share ideas 😉 #AcademicSky

I received this Victorian (~1850s) #microscope slide of a butterfly as a gift and was inspired to make a little video about it #sciart #microscopy 📽️ youtube.com/shorts/vVKCk... Apparently back then, people had microscopes at home as a form of entertainment! #scienceisforeveryone

I got a used Nikon Labophot #microscope to do some fun #scienceathome! Check out this video of bird bath water I was able to take through the microscope with my phone. Still learning to identify protozoan microorganisms though! #scienceisforeveryone 📽️ www.youtube.com/shorts/0X0nt...

Just got my Presidential Early Career Award #PECASE certificate in the mail! 🎉 Grateful for #NSF grants that power our #BiomedicalResearch. Words remind us that federally funded research creates valuable public goods that help us reach our full potential. #ScienceMatters #FundResearch #AcademicSky
