The lack of action by our collective governments is insufferable and painfull. And it seems they cannot be swayed by protest etc. We must all work hard to get better people elected. People that still have a soul and conscience.

Dr. Or M. Bialik |📚|🔬|🌊|⚒️ @obialik.bsky.social · Jul 15

I have a fully funded open #position for a PhD student/postdoc in marine #biogeochemistry. As part of the MARBEDS project, we are seeking someone to study seafloor fluxes and their interactions with microbial communities in biodiversity hotspots.
🧪⚒️🌊
Contact me if you want more details.

Open position for PhD student / Postdoc in biogeochemistry
For a fully funded four-year project exploring environmental and
ecological dynamics in the Mediterranean and Red Sea, we seek a top
tier PhD student or postdoc. The project aims to understand the
formation and persistence of biodiversity hotspots, especially in light of
global climate change and local stressors. The ultimate goal is to
gather insights across different organizational levels, from molecular,
organismal, and community to habitat structure and biogeochemical
pathways, in order to construct comprehensive models that forecast
the future dynamics and fate of these ecosystems under changing
conditions. This position would be focused on a key aspect of this
project – the variability of seafloor fluxes and their interaction with the
microbial community to facilitate the habitability of shallow (up to 40 m)
and mesophotic (up to 200 m) biodiversity hotspots such as reefs.

Interested candidates, please contact by email Dr. Or Bialik (obialik@ocean.org.il) or Prof. Eyal Rahav (eyal.rahav@ocean.org.il) with a letter of motivation, CV, and contact details of at least one referee for this post not later than the 28th of August 2025.
