First paper from my PhD is officially out! We uncovered how benthic diatom Nitzschia navis-varingica makes the neurotoxin domoic acid. Grateful to all our collaborators in the @BradMoore_SIO, Todd Michael, @andreweallen, and Mari Yotsu-Yamashita labs!

Domoic acid (DA) is a potent neurotoxin produced by marine micro- and macroalgae problematic to fisheries and toxic to humans and animals. Our study elucidates the molecular mechanisms underlying DA...
The benthic #diatom Nitzschia navis-varingica harbors massive genomes and an expanded domoic acid (dab) gene cluster (>60 kb). Genomics + biochemistry reveal enzyme diversification driving a unique toxin chemotype. @andreweallen @BradMoore_SIO

Many of you gave me so much encouragement when I posted here earlier about my 10 year long passion project to make a microbial map of the ocean. Pinch me because I can't believe I get to update you that today that research was published in the journal SCIENCE! (@aaas)

Former @JCVenterInst, @Scripps_Ocean, and Allen Lab PhD student @science_doodles tells her extraordinary scientific tale from classroom to ocean voyage to data generation and interpretation. Dr. Kolody overcame numerous challenges and was intrepid and curious at every step!!
I’m very excited to finally share the results of a passion project that has been on my mind for nearly a decade. You can find the pre-print below, but what follows is the saga of how this project came to be:

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias. It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵 https://t.co/hAzvDYoDyZ

Still recruiting PhD students in my lab - especially looking for candidates with marine nematode taxonomy skills right now! Base stipend is $32,000 at UGA, w low(er) cost of living here in Athens & great food/greenspace/events (inc. a halloween costume parade for dogs, COME ON!)
I'm recruiting THREE PhD students for Fall 2024 (nematode systematics, marine eDNA, invertebrate microbiomes) - more info here https://t.co/L4oIZlSpS6 including my mentoring philosophy + training portfolio! @SACNAS #2023NDiSTEM #BWEEMS #WomenInSTEM @LatinxMarineSCI @BlackinMarSci
