Are you an artist with experience with scientific illustration or translating scientific concepts into art? I would love to ask you some questions and/or promote you for an upcoming blog post on how scientists can work more with artists in their research 🎨

If I pull this off, we're going to have 3 new bug murals up in Philly this fall, all painted by women/nonbinary artists. 1 in a park, which will pair with an October event where we have a moth-themed drag performance & costume contest. 2 in neighborhoods & will come with science libraries.

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

Here is Supplementary Figure 18, which better showcases the beautiful illustrations we commissioned from @umich.edu undergrad Olivia Stein. These illustrated species represent clades where our method identifies significant increases in the rate of body-shape evolution. Also see Supp Table 7.

Supplementary Figure 18. from Berv et al 2026. Figure 1 is reproduced, with enlarged illustrations that are approximately to scale relative to one another and suitable for printing. Illustrated species
names are noted in Supplementary Table 7.

Happy to share this 'capstone' project from my time as a postdoc @umich.edu, where we show that hierarchically nested bursts of body-shape evolution may underlie much of perching-bird diversification over ~50 million years. Free access link here: rdcu.be/fuxB1
