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 🧪
a 2x3 grid of Smith / Carlson / N6 tiles (top) and their corresponding FFT (bottom). The patterns exhibit considerable amount of diffuse scattering.

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! elementalmicroscopy.com/articles/EM0... 🧪🔬

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 🙌 @elementalmicrosc.bsky.social

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! www.apmc13-2025.org/conference-w...

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 🙌 🧪 marimo.io/p/@gvarnavid...

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 🙌 📸: @juliedactyl.bsky.social
