My dissertation is now freely available: scholarworks.montana.edu/items/5f1522d5… It examines nanocrystal ligand effects on transport, lamellar structure influence on charge separation, and impact of noise in measures of excited state diffusion in semiconducting materials. �#chemskyk#perovskyky

Cozying up to kick off my birthday weekend with this remarkable new book by Toby Hendy @tibees.bsky.social. Look closely at the photograph: an inversion hides in plain sight! The fourth dimension may be closer than it seems…

I’m starting a new position as a part-time Middle School Science Laboratory Instructor!

I’ll spend an hour each week helping students explore the scientific method, nurture critical thinking skills, and connect with the Montessori tradition of self-directed cosmic education.

Meitner-Auger recombination: A process by which energy transfer between excitons causes one to recombine and the other to be excited to a higher energy state within the same energy band. It was discovered and published in 1922 by Lise Meitner and—independently—in 1923 by Pierre Victor Auger.

Happy Tau Day!

We celebrate both Pi Day and Tau Day at our house. Tau (≈6.28) is 2π, and some say it is the better circle constant. Either way, it is a great chance to talk angles, radians, and geometry with kids. Preferably over something round and tasty. #TauDay

Every science award given to multiple people should go to half who identify as women and half who identify as men. For odd numbers, alternate yearly.

“Best qualified” is no excuse. There are always more qualified people than awards. All-male award lists should be embarrassing.

Pão de Queijo! Easy to make:

170 g tapioca flour
1 egg
1/3 C olive oil
2/3 C milk
66 g cheese
1 tsp salt

Blend to homogeneity, 3/4 fill greased mini muffin pan, bake at 400 F for 15 min.

Spray the pan w/ canola oil because it is healthy and to spite RFK who hates it. #ChemistsWhoCook

The White House doubled down on Trump’s absurd claim that #DOGE canceled $8 million for “making mice #transgender.” In reality, none of the projects do anything of the sort. (Do mice even have gender identity?) Here’s what they actually study: 1/

Although she fell asleep every time we listened to Project Hail Mary (audiobook), the 5yo retained enough to draw this picture of Rocky, the alien in the book, almost a week after we finished listening.

My 10yo won first place in her class spelling bee today. So proud of her ❤️

Clearly, my recent paper might find itself in hot water with the ‘bias patrol.’ I suppose ‘systematic error’ just doesn’t have the same ring to it! #Optics #Photonics ⚛️ 🧪

Pleased to share our study on how substrate annealing affects CsPbBr₃ perovskite photoluminescence on TiO₂. We show how annealing temp tunes surface roughness, crystallinity & charge recombination.

Grateful to lead author Xavier Vorhies and co-authors!

Sweeping restrictions at NIH have halted grant reviews, workshops, and hiring. Travel and communication bans block scientists from presenting work, recruiting for clinical trials, and publishing. Fear and uncertainty now threaten U.S. biomedical research progress. 🧪 www.science.org/content/arti...

Starting a new lab?! The most important factors for choosing the university/institute/company are: the colleagues, students & postdocs, the leadership, equipment, the lab space and start-up funds; IN THAT ORDER.

We watched Nightbitch last night, and I loved it. A modern “Heroine’s Journey” that is raw, unsettling, and empowering. Not horror as billed, but a visceral, strange, and cathartic exploration of motherhood and identity. Highly recommend!

This excellent video by @acollierastro.bsky.social is a sharp, funny critique that explores the weird obsession billionaires like Elon Musk, Bill Gates, and Jeff Bezos have with #physics, and why they all want us to think they’re secret geniuses.

Why is so much of the scholarly literature inaccessible to blind and low-vision scientists (and other readers)?

My latest for Nature:

Accessibility worsens for blind and low-vision readers of academic PDFs
Preprints and other rapid-publishing trends have fuelled a decline in scientific publications meeting accessibility standards, study finds.
