Soil Biogeochemistry @ UNIL

Mineral-associated organic nitrogen pool size, composition, and accessibility mediated by agricultural management and soil geochemical characteristics Mineral-associated organic matter (MAOM) contains a substantial portion of soil nitrogen (N). MAOM-N could serve as an important N source for crops, b…

New paper! 🎉 Check out how soil organic N dynamics within MAOM are mediated by management and geochemistry. Team effort led by Rachel Hestrin and Gabriella Griffin + major contributions from @andreajilling.bsky.social and @stuartsoil.bsky.social + many others. www.sciencedirect.com/science/arti...

Job Alert 🚨 : Two-year Postdoc in Redox Biogeochemistry of Coastal Soils available. Focus on oxygen, metal and carbon cycling in the rhizosphere.

Very surprised (and pleased 😊) to be listed as 2025 Highly Cited Researcher for the first time!

Great occasion to thank all the amazing mentors, collaborators and team members that I have been lucky enough to work with over the years!

A recipe for avoiding 15 million deaths a year and climate disaster is fixing food, scientists say Scientists are presenting new evidence that the worst effects of climate change can’t be avoided without a major transformation of food systems.

When it comes to climate change, our diets matter — and matter a lot.

Not to mention for biodiversity, water, and especially our own health.

The updated EAT-Lancet report makes this abundantly clear.

NEW PAPER 🚨 Curious how plant root exudation and soil texture might interact to form dynamic anoxic microsites in the #rhizosphere, and what they might mean for the fate of soil #carbon, nutrient or contaminent in #soils? Check out @soiltycoon.bsky.social's new paper in SBB: doi.org/10.1016/j.so...

Time for new group 📷!

Really lucky to work with such a great group of people. Go Team!

We're super excited about my @unil.bsky.social colleague @pbenettin.bsky.social 's new Ecotrons! Fully climate controlled soil lysimeters! So many possibilities for manipulations and experiments!

9 Federally Funded Scientific Breakthroughs That Changed Everything

This is a good start.
While in government, I was dismayed by how the value of scicomm was devalued at multiple levels.
The hard truth: This is not just about better PR, without effective scicomm, we lose public support for critical investments that benefit EVERYONE.

Interested in spatially resolving microbial necromass formation and recycling? Check out Bouke Bentvelsen‘s poster at #EGU2025 today.

It's timely that I re-post a tweet from July, 2022 (if you know why, you know), which I made soon after I left my first postdoc. Many empathized with me then and still do today.

Lower survival rate among trainees in labs with highly productive mentors raises important concerns about what we value in academia. Many interesting things to stew over with this paper!
