This work started with a whiteboard discussion with @liangxu.bsky.social, where we sketched out a network of different microbial functional groups and filled the board with equations. It was an incredibly fun journey, and I truly enjoyed working together with the three of us throughout the project.

Did you receive a Student Research Award from the American Society of Naturalists @asn-amnat.bsky.social ? We'd love to hear what you achieved with those awards (or, please share with someone who had one), even going back many years: docs.google.com/forms/d/e/1F...

⚒️ Article: Nitrite-oxidizing bacteria contribute to the accumulation of nitrite in marine oxygen minimum zones through interactions with other microbes @xinsun-putiger.bsky.social @upenn.edu @carnegiescience.bsky.social www.nature.com/articles/s41...

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...

New research from Prof. Xin Sun of Biology offers an improved understanding of microbial ecology and geochemistry—key to forecasting global emissions in response to natural and man-made climate change. @upenn.edu @xinsun-putiger.bsky.social

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...

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...

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. Read on Mailchimp: shorturl.at/lDxXk Read on LinkedIn: shorturl.at/VOiPa

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! agu.confex.com/agu/agu25/pr...

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 🤣

@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: www.pnas.org/doi/10.1073/...

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...

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/...
