We are curious how interactions among organic matter, microbes, and minerals in soil drive and respond to climate change |

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!

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.

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.

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...

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!
The new Ecotron system manufactured by UGT and funded by the UNIL Faculty of Geoscience and the Environment @fgse-unil.bsky.social is operational! It's a rather big machine with a very big potential for ecohydrological experimentation.

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.

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.

*the original tweet is gone b/c I quit Twitter, but it has been archived elsewhere:
