Our paper "Nitrite accumulation in marine oxygen minimum zones induced by microbial nitrite consumers" is online @natgeosci.nature.com! We found that microbial nitrite consumers counterintuitively lead to nitrite accumulation in marine oxygen minimum zones! 🦠 🌊 www.nature.com/articles/s41...

In honor of the bagels Claudia and I ate during the cruise, I used a bagel analogy to talk about our key findings 🥯: penntoday.upenn.edu/news/penn-sa...

Oh no, Chris! I just saw this and I am so sad that I missed it! Is this seminar being released by any chance?

Mechanistic understanding of nitrate reduction as the dominant production pathway of nitrous oxide in marine oxygen minimum zones - Nature Communications Experiments and modelling unravel mechanisms of nitrous oxide production from nitrate, the primary nitrous oxide production pathway in oxygen minimum zones. Results highlight the critical role of microbial interactions in regulating this pathway.

Microbial ecology provides critical insights for biogeochemistry: we unravel mechanisms and controls of the primary N2O production pathway in marine oxygen minimum zones using both experiments and theoretical modeling. Great collaborators, amazing experience! www.nature.com/articles/s41...

Jane Goodall's final lesson Honoring Jane Goodall's life, Pope Leo's first climate address, and finding hope in action

This week, we lost one of the world’s greatest advocates for people and nature. Even in her final days, Dr. Jane Goodall was urging us not to give up, and now her legacy lives on through the countless voices she inspired.

congrats!

It was one of the most interactive departmental seminar I've given. Thank you @xinsun-putiger.bsky.social for hosting this seminar in the beautiful campus of Penn, Department of Biology! Astounded by a full room of people studying soil, marine ecology, plant biology, and earth/environmental science.

New paper in @nature.com! With @kiseokmicro.bsky.social , Siqi Liu, Kyle Crocker, Jojo Wang, Mikhail Tikhonov & Madhav Mani — a massive dataset and simple model reveal a few conserved regimes that capture how soil microbiome metabolism responds to perturbations. www.nature.com/articles/s41...

Another position from the same lab: again, amazing team, awesome advisor!

Amazing team, awesome advisor! Don’t miss this excellent opportunity!

Calling all marine microbe enthusiasts! Please check out our session and we look forward to seeing your abstracts!!

We are organizing a session on the aquatic nitrogen cycle at AGU this year! The abstract deadline is the end of this month (July 30), and a link to our session is attached below. Look forward to your contribution!

First two weeks as an assistant professor: loving my colleagues, grateful for all the help from our staff, impressed by science happening in the department, and shocked by how quickly I lost heat tolerance after only three years in California 🤣

Thank you so much for sharing, Daan! I miss seeing you all and all your amazing science!!

@xinsun-putiger.bsky.social kicks off the ocean session #ICoN9 with a fantastic talk explaining why nitrite accumulates in ocean oxygen minimum zones.

The work is still in review but builds on her recent work on modeling ocean denitrification:

Thank you! Thanks for the key inspiration from your work!

Oxygen intrusions sustain aerobic nitrite-oxidizing bacteria in anoxic marine zones Anaerobic metabolisms are thought to dominate nitrogen cycling in anoxic marine zones (AMZs). However, thriving populations of aerobic nitrite-oxidizing bacteria (NOB) in AMZs challenge this assumptio...

Excited to share our new paper on how aerobic nitrite-oxidizing bacteria persist in anoxic seawater: www.science.org/doi/10.1126/...

Today at the Stanford Bug Club (Advanced Seminars in Microbiology), thanks to my amazing team members, we won the microbiology-themed charades, and I got an E. coli!

Thank you, @usocb.bsky.social, for sharing our recent work: www.us-ocb.org/how-do-ocean...

Thank you!! So glad to be here!!

Huge thanks to Dr. Mike Beman for an amazing commentary on our article! www.pnas.org/doi/abs/10.1...

First post: 🦠🌊Denitrification is the main nitrogen loss process, but how do microbes performing different steps coexist? We outline the rules governing this coexistence and explain why some denitrifiers are more abundant than others in the ocean. Check it out here: www.pnas.org/doi/10.1073/...
