Professor of Statistics at Swarthmore College. I use statistics to study paleontology, evolution, and extinction. I also compose percussion music for fun.

Now that videos work on Bluesky, here's a snippet of my Sextet for Percussion, performed at @swarthmorecollege.bsky.social in 2016. Scored for marimba, vibraphone, xylophone, and two pianos.

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :(

So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

Happy Ctenophore Day!
🐙🦑🧪
A graphic that reads Happy Ctenophore Day in glowing pink text twice between three rows of different ctenophore species. The top row is lobate ctenophores including Bolinopsis microptera, Leucothea pulchra, Mnemiopsis leidy, and the bloody belly comb jelly Lampocteis. The second row has three different Beroe species. The lowest row has Pleurobrachia bachei, Dryodora glandiformis, red-x, and Euplokamis dunlapae.

When does biology become geology? This is a fun paper for us (although I, myself, was just one more member of Band-Aid for this particular paper), and hopefully it helps clarify a lot of things that we sort of already knew but never really formally addressed.

I'm a longtime Poscast listener (since 1957) and statistics professor. Re: solitaire win%: at 350 games, the SD is 2%. Meaning 68% of the time, your win% will be accurate to within ±2%, and 95% of the time, your win% will be accurate to within ±4%.

I think we also get distracted because we tend to anthropomorphize the larval stage as the child and the adult stage as the real animal. In some cases (not necessarily holothurians, but perhaps e.g. butterflies), it would be more appropriate to think of them as the eating stage and the mating stage.

📢 deeptime: an R package that facilitates highly customizable and reproducible visualizations of data over geological time intervals

🔗 doi.org/10.1080/2096...

Fully #openaccess in @bigearthdata1.bsky.social with insight about deeptime📦 development and code examples!

Plot of global benthic δ18O data for 0 – 5.3 Ma (Lisiecki & Raymo, 2005) with geomagnetic polarity subchrons displayed on the top x-axis and planktic foraminiferal primary biozones plotted on the bottom x-axis using the deeptime package. A mammal phylogeny (Garland et al., 1992) plotted in the fan layout using the ggtree and deeptime packages. The greyscale concentric circles in the background indicate geological stages, whereas the linear colored timescale indicates geological epochs. Early tetrapod occurrence data (Jones et al., 2023) plotted as a taxonomic/biostratigraphic range plot using the geom_points_range() function from the deeptime package. A stratigraphic column of Cretaceous lithostratigraphic units from the San Juan Basin, USA. The deeptime package has been used to add pattern fill which indicate the primary lithologies of the units as reported by the Macrostrat API (Peters et al., 2018) via the rmacrostrat R package (Jones et al., 2024).

Chuck Mangione was a musical hero to me. He was from my hometown, where he was a legend. My mom took me to see him in concert when I was 13, and it was a life-changing moment — he made me love music.

Another of the greats leaving us. Dick was a huge influence on me when I was a graduate student, and wrote papers that completely changed the way I thought about the history of life. A gracious and good-humored man, and a kind and supportive mentor.

A great loss to paleontology. Bambach‘s work was in many ways foundational.

Richard Bambach, 1934-2025. A warm and generous man, and a titan of paleontology.

Very sad to hear of the passing of Richard Bambach, one of the key paleontologists who ushered in the paleobiological revolution, and an incredibly kind and generous person. It was a pleasure learning from him at the Smithsonian’s paleo journal club over the last decade or so.

Richard Bambach will always be remembered as a champion of functional-ecological way of thinking in macroevolution. Way before the modern trend in analyzing functional diversity.

Very sad to learn Richard Bambach has passed away. In addition to his significant contributions to science and the 'paleobiological revolution', I will mostly remember him as a warm and wonderful presence in our paleobiology journal club when I was a postdoc at the Smithsonian

Swarthmore College has a teaching collection of fossil plants that has probably not been used in decades, recently re-discovered when we moved into a new building. We are hoping to catalog/digitize them. Can anyone ID any of these specimens beyond the brief descriptions on the cards? (1/2)
A wooden box of plant fossils. Note card says, "Cannel coal, made up of flattened Lepidodendron spores" (referring to some of the specimens; not sure what the others are). A wooden box of plant fossils. Note card says, "Fern fronds from St. Clair PA. Carboniferous." A wooden box of plant fossils. Note card says, "Vaguely relevant but interesting..."
