Achal Agrawal realised how ingrained research misconduct had become, and resolved to do something about the issue He is part of Nature’s 10, a list of people who shaped science in 2025 go.nature.com/3Yk3d0T

Just wrapped up a 1-hour talk at the Dpt. of Geological Sciences, Jadavpur University, India. What an experience! Loved the interaction with the students. Such an energising session! Thanks to Prof. Nibir Mandal for organizing the seminar.

Bored by the Lower Mantle? Think again! In my new @egu-gd.bsky.social blog, I talk about how we model deep mantle dynamics and use seismic anisotropy as a diagnostic tool to compare models with real observations, revealing a lot more going on down there than we think. blogs.egu.eu/divisions/gd...

New blog alert! This week Poulami Roy attempts to change our minds about the lower mantle - what if it is not *that* boring after all? blogs.egu.eu/divisions/gd... #egu #egugeodynamics

Happy to share that our recent paper on global-scale geodynamic + seismic anisotropy simulation is on Eos spotlight. With @bstein.bsky.social , Manuele Faccenda , @michapons.bsky.social Enjoy reading! :) eos.org/research-spo...

How do BLOBs in Earth’s mantle affect seismic waves? Research by @poulamiroy.bsky.social & @bstein.bsky.social of @gfz.bsky.social and colleagues offers new insights. eos.org/research-spo...

3rd paper from @poulamiroy.bsky.social's Ph.D. just out at doi.org/10.1029/2025.... Combined global models of mantle flow and anisotropy constrain deformation mechanisms and viscosity, density and hence compositional structure of lowermost mantle. With Manuele Faccenda, @michapons.bsky.social & me.

What’s happening 3000 km beneath our feet? Can mantle plumes rise all the way from that depth to the surface? How do we trace mantle flow down there? Can seismic anisotropy let us ‘see’ it? We explore this in our latest paper agupubs.onlinelibrary.wiley.com/doi/10.1029/... (co-authors in comment)

Scientific recycling: In doi.org/10.1029/2024... I use results from Poulami Roy's Ph.D. thesis to address why plume excess temperatures are much less than temperature drop across the lowermost-mantle thermal boundary layer. Further co-authors @michapons.bsky.social and Matteo Jopke. (continued)

Wondering what is the anisotropic signature of slab-induced plumes from thermochemical piles in the lowermost mantle? Then find out from Poulami Roy's paper agupubs.onlinelibrary.wiley.com/doi/10.1029/... co-authored by Manuele Faccenda, @michapons.bsky.social and myself
