Background Rubisco is among the most abundant enzymes on Earth and is a critical conduit for inorganic carbon into the biosphere. Despite this, the full extent of rubisco diversity and the biology of...
it's preprint day! happy to share my first piece of postdoc work as well as my first in the marine space, this time, exploring the biology of bacteria and archaea fixing carbon with rubisco in the deep water column

Cyanobacteria are highly abundant in the marine photic zone and primary drivers of the conversion of inorganic carbon into biomass. To date, all st...
cyanobacteria can have multiple distinct forms of rubisco! check out our new preprint to learn about the unusual carbon fixation machinery of an low O2 prochlorococcus and what we think it might mean for physiology and ecosystem biogeochem

Making science accessible has its challenges but is worth tackling, especially when it comes to including more deaf scientists in the scientific enterprise. Read the article:

big thanks to coauthors and to the developers of branchwater ( https://t.co/znEG0511CT) for helping make this study possible definitely check out this great tool if you want to expand metagenomic sampling for your group of interest in an efficient+ targeted way!

this story was an unexpected branch off of a larger piece of work surveying rubisco across global marine environments.. sometimes the “that can’t be right” observation turns into some really interesting biology https://t.co/Rtbo91CKZz

In @UCBTagaLab Zoila, @ZHallberg, and I dove into studying the impact of nutrients like Vitamin B12 (corrinoids) on community-wide & isolate-specific scales. How often do you see paired studies like these?! Our sibling papers are out now in @ISMEJournal!

Abstract. Soil microbial communities perform critical ecosystem services through the collective metabolic activities of numerous individual organisms. Most
My first, first author paper is out in @ISMEJournal ! Over the past few years in the @UCBTagaLab we have been learning about how soil bacteria share corrinoids, largely thanks to funding from @DOEScience. Here, we got some answers by studying isolates.🧵 https://t.co/W6wPbgx1rZ

3rd chapter of my dissertation finally published in @NatureComms! We reconstructed the first complete Asgard archaeal genomes from short reads, validated with long reads. Genome structures & metabolic insights reveal key roles in carbon/hydrogen cycling in wetlands.

this out today from @NestorArandia + the rest of us in @annedekas lab exploring the role of urea in the interconnected deep sea nitrogen and carbon cycles! a fun opportunity to consider how best to merge single-cell (nanosims) and bulk community (metagenomics) analyses.
Urea assimilation and oxidation supports the activity of a phylogenetically diverse microbial community in the dark ocean https://t.co/2o0bhB9uNJ

really worth consideration for microbial ecologists looking to bring new dimensions to their work through modeling, plus a fabulous group and location!
The Global Microbial Ecology group at Carnegie Science (i.e. Zakem group) is hiring a postdoc! Location: Pasadena, CA (Caltech campus). Spread the word! https://t.co/jUu7lGa1Rh
