True confession of a nerd 🤓: Is anyone else obsessed with GitHub? I just get so much satisfaction from seeing all my #rstats code in a tidy repo.

Epic! Thanks!

I am honored to have been interviewed about #agroecology by Unsustainable magazine, a publication dedicated to exploring human interactions with the #environment and promoting #sustainability.

Nice! Now that I’ve gotten past the initial learning curve of using an HPC, I don’t see myself going back to buying more SSD storage or having R run for days on my laptop. Enjoy! 🤖

Ps. I checked out your lab website, seems like you do some really cool stuff!

I ran into a similar issue recently. Fortunately, I was able to move my work onto my university’s high-performance computer cluster. Perhaps that will work for you too?

Now with a News & Views: "Novel crop rotation via de novo pennycress domestication" rdcu.be/e2vpe

A new winter-rotation oilseed crop has been generated from a freeze-tolerant wild field pennycress by de novo domestication.

New Article: "Creating a new oilseed crop, pennycress, by combining key domestication traits using CRISPR genome editing" rdcu.be/e0NAR

De novo domestication by identifying and stacking CRISPR-induced mutations to create a new intermediate off-season oilseed crop.

ICYMI with a quick screenshot as sales pitch. Simply feed your estimation a bunch of .parquet files on disk and run it as normal.

This example takes 180m rows of NYC taxi data and computes the model in < 1 second.

On a laptop.

I was hoping for a la lme4. Alas, a boy can dream!

This looks really cool! Is there a way to run generalized linear models and/or include random effects terms?

YouTube video by Música Espacio Kuyen El derecho de vivir en paz

Victor Jara's song "El Derecho de Vivir en Paz" (The Right to Live in Peace) is a good reminder that everyone has the right to life, liberty, and the pursuit of happiness because, as our nation's forefathers astutely pointed out, we are all created equal.

Thanks!!

One (perhaps naive) question, @andrew.heiss.phd, are there any major tradeoffs to using matching and IPW compared to a model that accounts for confounders through fixed/random effects? For example:

lm(malaria_risk~nets+health+income+temperature)

Currently binging your Matching and IPW videos. Really great material! Thanks!

Models are used to explore the global #foodsystem, incl. implications for #nutrition, with unclear confidence. In a #SensitivityAnalysis of a model, variations in the calculated supply of some nutrients led to qualitative changes from sufficient to insufficient global supply: doi.org/10.1007/s125...

Why research #agroecology? Because the way we manage our farmland is one of the largest drivers of natural habitat loss and greenhouse gas emissions. #Sustainable agriculture is not just about food production; it's also about #conservation and climate change mitigation.

GitHub - UrielMenalled/workshop-BayesianR: Learn about Bayesian analysis theory and its application in R Learn about Bayesian analysis theory and its application in R - UrielMenalled/workshop-BayesianR

Are you stuck on the fundamentals of Bayesian analysis? For a long time, I was. Sure, I was familiar with the equation P(A|B) = [P(B|A)*P(A)] / P(B), but it was hard to internalize.

To this end, I've made an #RStats workshop on Bayesian analysis. Check it out on GitHub:
github.com/UrielMenalle...

Really cool package!

Interesting to see as a member of another Montgomery County (Montgomery County, VA). Could you put up the code on GitHub? I'd love to adapt it for my Montgomery County.

2026: Chaotic but in a fun way

On that note, I'm hiring a Master's student for Fall 2026! Please spread the word 📣

Big news! I'm starting a tenure-track position in Agroecology at Montana State University in Fall 2026!

I feel incredibly honored to have this opportunity.

A field of Kernza with the sun peaking behind it

A while ago, I wrote about the future of Kernza and perennial grain research. A concern I voiced was that, as grain yields increase, the plant would move from investing resources in roots and biomass in favor of seed yield, denuding the plants ability to curtail erosion and improve soil health.

🧪 EXPERT VIEW 🧪

🚜 One of the main challenges facing agriculture is the control of plant development without using chemical compounds harmful to the environment.
💡 Here, Thuleau et. al. present regulatory peptides as interesting potential alternatives.

Will sessions focus on Python, R, Julia, etc.??

2) But the real elephant in the room is *your effect of interest*. @aaronjfisher.bsky.social is right in that statistical significance doesn't tell you if an effect is practically or theoretically meaningful. But that neither means that p-values are useless, nor does it depend on the sample size. >

I'm sorry, this is a shame, and I hope that change comes soon to the USA 💔.

I remember that one of my first research jobs was manually selecting areas of developed vs. undeveloped areas around Patagonia to study habitat fragmentation. With Earth Index, I could have worked much faster!
