Happy to announce my new paper in Nature Protocols! 🥳 It is supposed to serve as a guide mostly for life and environmental scientists that want to delve into the stable isotope analysis using Orbitrap mass spectrometry. INSTAAR 🏳️‍🌈 CU Boulder 🦬 nature.com/articles/s4159…

Dr. Mueller! Thanks to everyone who came - from near and far - to watch me defend my PhD. Grateful for my years at Caltech and excited for what’s ahead.

Secondary production and priming reshape the organic matter composition in marine sediments science.org/doi/full/10.11…

Thrilled to share that I will be joining Boz Wing's group and the rest of the geobiology folks at CU Boulder 🦬 as a NASA Postdoctoral Program fellow! We will start a project near and dear to my heart, unraveling how microbial fermentation influences global biogeochemistry.

Organic P recycling without biology? Is this missing piece in #phosphorus #geochemistry? Just published Nature Communications, Aristilde Lab @ Northwestern Engineering reveals #iron oxide minerals as #catalysts cleaving phosphate from biomolecules in #soil and #sediment.

Please share! Our lab is recruiting PhD students and/or postdocs for Fall 2025. Projects may include a combination of fieldwork, isotope geochemistry, and modeling. Reach out to discuss if interested!

Very proud of this study. Cait Welsh, Forster Lab, Princess R. Cabotaje, Ph.D., Berggren@UU, Lyras Lab, Vanessa R Marcelino, and Duncan Kountz.

Super excited to share our new review article on the diversity and ecology of microbial sulfur metabolism. Please RT and share. Chao (Zhichao) Zhou Patricia Tran, PhD nature.com/articles/s4157…

Me and 13 great collaborators! Including a fantastic summer student who helped to solve perhaps the most challenging part of the project: How to isolate acetate (to measure its D/H composition) from a brine 5x saltier than seawater??

🚨Paper alert🚨Finally published my paper titled,”Long-term interaction of metals and phosphate with ferrihydrite in artificial seawater and implications for past and present environments.” Link here: sciencedirect.com/science/articl…. (1/3)

My group (HessLab.com) is recruiting a new Junior Specialist to support our ongoing efforts in understanding and editing the rumen microbiome towards lower methane production. Please apply here before Dec 1st 2024 recruit.ucdavis.edu/JPF06793
