Andrea Castillejos

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

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: pubs.acs.org/doi/10.1021/ac… @EnvSciTech @microsensors @MicrocosmEarth

Our paper on reactive oxygen species in intertidal permeable sediment is out: nature.com/articles/s4146…

📢#PhDpositions alert! Are you passionate about geomicrobio/paleoclimate questions and want to join a multidisciplinary team? We have 3 positions available. Join us on this research journey (that might take you to the top of the world) 🏔️🦠👩‍🔬 @unibern @unil @snsf_ch @icdpDrilling

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

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! ✨

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

@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 🧪

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

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

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

Team Microsensors at #EGU22 ✨

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

@freexuelin Nooooo 😱😱😱

So exited to share my first paper! Here’s how to measure tiny amounts of #arsenic by #colorimetry in as little as 100 microliters 🎉: Arsenic speciation analysis in porewater by a novel colorimetric assay sciencedirect.com/science/articl… #ArjunChennu #CarolinKerl #LaisGatti #JudithKlatt

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

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

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!

For the next game, players must peel off an ancient piece of autoclaving tape while wearing gloves

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