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.

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...

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.
