Today is the last day of the ham class! We're building measuring tape Yagi-Uda antennas (based on N5DUX's excellent plans). A rite of passage! This was actually the first time I built one... Any tips for getting the reflector to lie flat on the PVC cross piece?

I found this in the library today and I'm loving it! Will have to order a copy of my own. Such a neat collection!

Congrats to our engineering faculty CMU Buggy team on winning against CMU Mellon College of Science!

Had a mini field day on Flagstaff Hill. Nabbed SP1DX in Slovenia on 10W sideband! Beautiful day for some amateur radio with the 18059 class :)

Grad students: attend this workshop if you can! Learn how to talk about your science from some skilled raconteurs!

Cormac McCarthy died today, June 13, at his home in Santa Fe, NM. Nautilus couldn’t have been more flattered when the great novelist published his first work of nonfiction, “The Kekule Problem,” with us in 2016. nautil.us/the-kekul-prob…

Come talk to me at the ASEE poster session Monday morning about teaching circuits to non-majors! I'll be at board 88 (Impact of Electronics Design Experience on Non-majors' Self-efficacy and Identity) #asee

Our signal propagation atlas of C. elegans is now out in nature! We measure the network’s response to optogenetic stimulation of each neuron in the head, one at a time-- over 23,000 neuron pairs. Congrats to Francesco Randi Anuj K. Sharma & @DvaliSophie. nature.com/articles/s4158…

A lot of undergraduates ask me "how do I learn more about batteries" so I decided to write my answer up: chang-lab.notion.site/How-To-Become-…

Eel-ectroporation!

Actin filaments that drive amnioserosa cell shape changes during dorsal closure in Drosophila, (i.e., cytoskeletal contractions during fruit fly development) as seen by grazing incidence structured illumination microscopy: doi.org/10.1091/mbc.E2…

My final project during my PhD is out! We electrically stimulate 3D epithelial structures to inflate like a water balloon. Much thanks to Alejandro Martínez Calvo , @Sameeksha Rao, @Isaac Breinyn, and the fearless leader Daniel J. Cohen (CohenLab at Princeton) ! nature.com/articles/s4146…

A kind stranger captured us during totality on Lake Erie! Luna was not as excited by the corona.

How awesome that this is out! Although feeling a twinge of disappointment felt that "Pump it up" didn't make it into the final pub's title...

Step aside muscle, our new work shows that kidney and intestine tissue can also change shape and function when electrically stimulated (movie)! We call this ‘electroinflation’! Long overdue hurrah for Gawoon Shim* /IsaacBreinyn*, Alejandro Martínez Calvo, Sameeksha. nature.com/articles/s4146…

One of the most rewarding things I get to do is run a week-long science storytelling workshop each summer with my friend Annetta Black of Odd Salon and (thanks U.S. National Science Foundation and Princeton Council on Science & Technology!). It's time for Lab Tales #4! Funding for 5 non-Princeton trainees. Apply: forms.gle/Eagrqatp1UUyJn…

In the age of satellites, cell towers and web servers, CMU offers amateur radio course. wesa.fm/education/2024… #amateurradio #hamradionews

wesa.fm/education/2024… I got to talk about our amateur radio seminar on... public radio! Thanks for having me, WESA. Ham radio lives on, and the field day was quite exciting this year (though still cold, in true Pittsburgh April fashion)!

Really excited to share our preprint on #Galvanotaxis! We identify Galvanin, a membrane protein acting as an electric field sensor that guides cell migration. Check it out: biorxiv.org/content/10.110… #CellBiology #CRISPRi #Migration (Thanks for the support @JCChildsFund and @NIGMS)
