May your soul rest in eternal peace and power, Rev. Jesse Jackson. I had the honor of meeting him my first week in DC, as I started my DOE appointment. He couldn't have been kinder. That moment served as an incredible motivator as I began my journey in government. A giant, in every sense.

Please help us spread the word about this great opportunity for a scholar with a strong publication, and funding record related to climate and environmental research; and excellent written communication, organizational, and interpersonal skills. aprecruit.ucmerced.edu/JPF02050

I just returned from Dakar where I co-chaired the NASEM US-Africa Frontiers in Science, Engineering, & Medicine symposium tinyurl.com/ybdjn22m. It was an extraordinary gathering of leading scholars from across Africa & US discussing timely research. Truly one of the highlights of my career!

New paper on role of polyvalent cations in buried soil C stabilization led by my former lab group members Manisha and Teneille, working with the best collaborators.

Attending today's California's First Nature Based Solutions Summit, it was so lovely to meet our @ucmerced.bsky.social @snriucmerced.bsky.social alumni who now hold key positions across the state.

A lot going on in the world these days. It is an incredible privilage to live & work in our state where today CNRA, CARB and CDFA hosted California's First Nature Based Solutions Summit. It was an honor to be invited to speak along with many folx I admire. So much soil love throughout the day 🤎!

It was so lovely to meet you in person @christinatoms.bsky.social. Sci-twitter connections are the best!

The science breakthrough of 2025 is Solar Energy, not because it is new but because of how successful its deployment has been. This year renewable energy surpassed coal as a source of electricity worldwide. Hopeful sign for what’s to come. www.science.org/content/arti...

TFW your professional society, at a conference you've been attending for 20+ years, finally gets your name to appear on the badge correctly. #AGU25

If you are going to be at AGU, you don't want to miss this one. I am so looking forward to Markus' 2025 Reeburgh Lecture.

Grateful to MacKenzie Scott for her $38 million gift ... the largest in UC Merced's history, surpassing even her own record-setting donation to our campus in 2021. She continues to be one of the few doing billionairing right. news.ucmerced.edu/news/2025/uc...

Happy world SOIL day all! Soil is life! Soil is beautiful!

Please nominate your self and/or others to review the the United by Nature Assessment (formerly the US National Nature Assessment). Spread the word.

On this #GivingTuesday, if you are able, please support local scientists working to address some of the most pressing environmental, climate, and related challenges at the @snriucmerced.bsky.social Make a gift today: lnkd.in/girEEWra Learn more at snri.ucmerced.edu Follow us on social media.

Honored to be featured in this piece celebrating 30 yrs of the Hellman Fellowship program! This early support was instrumental in setting my lab for success. Grateful to the Hellman family for their vision in supporting junior faculty across the UC. www.universityofcalifornia.edu/news/society...

The fervor around college sports in the US will always fascinate me. And, when my child is excitedly rooting for his school's team, I can't help but cheer as they crush the visitors today.

“Our work matter today more than ever!” -Dr. @aaberhe.com @SACNAS #NDiSTEM2025

🧪🍎⚒️ Hey @sacnas.bsky.social What a fantastic keynote from @aaberhe.com ! She talked about soil science, weathering, and erosion as a metaphor for overcoming challenges. Every rock has a Story! youtube.com/@everyrockha...

this is a relief. But more advocacy will clearly be needed going forward. The PPFP is an exemplary program. I’m a proud former President’s postdoc fellow, and always a supporter of this critical program.

Land degradation remains one of the most serious and persistent global challenges. This deserves to be a global priority for science, policy, and more. www.fao.org/newsroom/det...

Merced and SJV folx, join us for the Sierra Nevada Research Institute's inaugural Distinguished Climate Speaker Series event featuring @michaelemann.bsky.social @ucmerced.bsky.social

Bonus, got to attend a performance at the Salt Lake Tabernacle, the historical home of the Mormon Tabernacle Choir.

#CANVAS2025 (ASA,CSSA, SSSA) at Salt Lake. I love the new format of the opening ceremony & our keynote panel. It was fun to imagine the next 40 years of research undertaken by our scientific societies and how we are doing in preparing the next generation of scholars and thought leaders.

My article on the Soil Collection at the Memorial for Peace & Justice in Montgomery, AL, which honors victims of racial terror, is published in CSA News. As a soil scientist, I was struck by the profound symbolism when I learned about this collection. www.sciencesocieties.org/publications...

As always, SACNAS @sacnas.bsky.social continues to be vibrant, brilliant, and healing. I’m so grateful for all the love showered on me yesterday.

Energized and hopeful after attending the annual meeting of the @uc-ppfp.bsky.social with a new fellow in our department & my wonderful @ucmerced.bsky.social colleagues.

The application is now open for the UC President’s Postdoctoral Fellowship Program. If you are interested in applying for this fellowship to work with me, do reach out and visit the How to Apply section for key dates and application requirements. see lnkd.in/gKafRtku

First day of teaching! Excited to be teaching a graduate-level soil organic matter dynamics class—the largest grad class I've taught to date! Students are eager to learn all about soil, carbon, and more. I'm always so excited to teach this class.

It was a pleasure to visit @woodwellclimate.bsky.social and engage in many wonderful conversations. Many thanks to Taniya RoyChowdhury for the invitation.

It was a pleasure to meet Dr. Asmeret Berhe @aaberhe.com (former Director of the Office of Science at the Department of Energy) during her visit to @woodwellclimate.bsky.social today. Excellent talk on soil carbon/precipitation shifts, and smart perspective on the future of federal climate science

Thank you @aaberhe.com for visiting @woodwellclimate.bsky.social and the Climate Justice seminar today and sharing your science and insights! Such a gift to be in conversation with you again, and thanks for modeling scholarship and leadership rooted in community, inclusion, diversity, and curiosity.

This is an irresponsible take on a v. complex issue. Landmines are responsible for deaths of countless animals, they cause serious land degradation, chem pollution, physical disruption, and impede sustainable development. Keeping people away is not the only thing that matters 4 nature conservation.

🎓 Congratulations to our newly minted PhD, Dr. Melinda Gonzales! Special thanks to @beccaryals.bsky.social for stepping in to advise Melinda during my extended leave and continuing as a wonderful mentor and co-advisor. Grateful also to our awesome committee members for their guidance and support.

This is new @agu.org Has this ever been a thing before this year? Did I just miss this?

A colleague suggested a circular authorship list without any order, and I thought it would be fun to ask Claude.ai (@anthropic.com) to create one with a wordplay using soil orders. I had a quick chat with it for 2 minutes, and it came up with this result without me writing a single line of code #AI

In a letter in @science.org , 9 scientists in 7 countries Poland, Ukraine, Norway, Spain, US, Finland + Croatia, warn against deployment of explosive weapons as countries that border Russia withdraw from conventions that restrict them w/ @katzyna.bsky.social, @aaberhe.com Check 🧵by @aaberhe.com 👇

In a letter @science.org we—9 scientists in 7 countries—warn against deployment of explosive indiscriminate weapons as countries that border Russia withdraw from conventions that restrict them, imperiling civilians as well as wildlife & ecosystems #landmines #UXO #ERW www.science.org/doi/10.1126/...

🚨Published today in @science.org. I join 8 scientists from 7 countries to warn that the world is sliding backwards from the promise of a mine-free future. 5 countries bordering Russia are withdrawing from the 1997 Mine Ban Treaty—& we/nature will pay the price. 1/n www.science.org/doi/10.1126/...
