The code to generate the Smith / Carlson / N6 tiles is adapted from Ned Batchelder's brilliant blog post: nedbatchelder.com/blog/202208/...

Also, here's the picture of the mentioned quilt and its FFT!

Went to a cool BAMPFA exhibit this weekend, on African American quilt making! Recognized one of the patterns as a Truchet tiling, and wanted to know what its FFT would look like. Would the symmetry pop up? Would the diffuse scattering??

That led to this fun exploration of Smith/Carlson/N6 tilings 🧪

Introducing the Curious Beams Lab — where we use electron beams and advanced algorithms to image the structure and function of materials at the nanoscale 🔬

PhD & postdoc openings coming soon — stay tuned!

Split figures are great for papers. For talks, interactive sliders are better 🙌

Here, demoing the upsampling capabilities of tilt-corrected BF STEM and direct ptychography on a beam-sensitive MOF dataset!

Super proud of this work, which showcases modern scientific publishing for open science 🧪

Inspired by the insights of the interactive CTF widgets, we propose a novel phase-retrieval algorithm which achieves robust information transfer on sub-sampled datasets 🙌

Attending the APMC 2025 in Brisbane, and interested in learning how to simulate and analyze 4D-STEM data? There's still time to register for the 4D-STEM workshop and learn about strain and orientation mapping, differential phase contrast, ptychography, and more!

Needed to demonstrate this fun example of solving Sudoku puzzles with projection set algorithms for a workshop I'm teaching. Continuously impressed with how easy it is to get to a working demo with wasm + @marimo.io slides 🙌 🧪

Hello 🧪🦋 New here, so figured I’d introduce myself! I’m a postdoctoral researcher @berkeleylab.bsky.social exploring the mesmerizing corners of diffractive imaging ✨

Short clip of my new favourite teaching demo: nanofabricated Fourier atlas by @hovden.bsky.social lab 🙌
