So happy to have had the opportunity to join, to talk science and wear some fantastic collars.

[Andrea Castillejos @Casti_Andy]

It’s out! I’m so excited to finally share our new method to map both arsenite and arsenate in soils & sediments in 2D! Check it out here: https://t.co/0ZKvVKyVjI

Thanks to @microsensors for letting me be a part of the lab group! It’s been beyond educational 💖

[Microsensors - MPI Bremen @microsensors]

Congratulations to ⁦@Casti_Andy⁩ for her outstanding PhD defense! 🎓

[Microsensors - MPI Bremen @microsensors]

Dr. #JudithKlatt is branching out and starting her own group in Marburg, check out @MicrocosmEarth to follow updates on her research on ancient photosynthesis. Best of luck! ✨

[Microsensors - MPI Bremen @microsensors]

Congratulations to @Elisa_Merz on successfully defending her PhD thesis on ‘The Dark Side of Diatoms’. We’re so proud of you!

[Microsensors - MPI Bremen @microsensors]

@Casti_Andy is now presenting her work on #arsenic speciation “Two-dimensional imaging of arsenic concentration and speciation with diffusive equilibrium in thin-film (DET) gels” at #EGU22 🧪

[Andrea Castillejos @Casti_Andy]

Field-usable, fine-scale mapping of arsenic species in 2D? We did that. Join my talk tomorrow to find out more, at 14:30 in session SSS7.3 #EGU22

[Microsensors - MPI Bremen @microsensors]

Jan von Arx from @BiogeoMPIBremen presenting “Aerobic methane production in the western Tropical North Atlantic” at #EGU22 🌊

[Microsensors - MPI Bremen @microsensors]

@maritvanerk is now presenting on “Reactive oxygen species control mineralization in permeable intertidal sediments” at #EGU22 🏝

[Andrea Castillejos @Casti_Andy]

Team Microsensors at #EGU22 ✨

[Microsensors - MPI Bremen @microsensors]

@Elisa_Merz kicking off Microsensor’s participation at #EGU22 with her talk “Sulphide stimulates nitrate reduction in benthic diatoms from a microbial mat”

[Andrea Castillejos @Casti_Andy]

@freexuelin Nooooo 😱😱😱

[Andrea Castillejos @Casti_Andy]

So exited to share my first paper! Here’s how to measure tiny amounts of #arsenic by #colorimetry in as little as 100 microliters 🎉:

I've never really gotten the "all the scientists are hiding the truth from us" angle of climate change deniers.

Like, have you met a scientist??? We're basically incapable of shutting up

[Andrea Castillejos @Casti_Andy]

I’ve never felt so personally attacked by a movie dialogue.

[Marit van Erk @maritvanerk]

Sampling Svalbard fjord sediments:
Was it dark? Yes (polar night)!
Was it cold? Yes!
But, or actually, because of that: what a great sampling experience!

[Andrea Castillejos @Casti_Andy]

So happy to be able to give a talk in person, and to spread omics excitement into a geobiology conference!

[Microsensors - MPI Bremen @microsensors]

Amazing talk by @Casti_Andy on redox dependent arsenic biotransformation #arsenic #microbialmats @microbialites 2021 in Paris
