Merci ! Une très belle récompense qui, bien qu’individuelle, reflète des années de collaboration avec étudiant•es et collègues, la chance d’avoir bénéficié d’un enseignement public de qualité et d’avoir trouvé tôt, dans la recherche publique, les conditions pour développer des travaux fondamentaux.

Current Vacancies

I am hiring 4 postdoctoral researchers for up to 4 years each. Topics include ice sheet reconstruction, GIA, spatial stats, and satellite geodesy. Based in Tasmania.

Climbing Through a PhD – Mental Health on the Way to the Summit Imagine you are going on a long mountain tour. Your backpack is heavy, the path is steep, and although you have been walking for hours, all you can see ahead of you is the next climb. Doing a PhD is l...

🧠 How are you, really?

Today is World Mental Health Day - a reminder that caring for your mind is important.

Kristin Vielberg and Hanna Sänger from PhDpositive reflect on the mental health challenges of doing a PhD and share ways to make the journey more sustainable, fulfilling, and balanced. 🌱

It’s goodnight Vienna as Paris sleeper train to Austria and Berlin hit by cuts Some Nightjet services suspended from mid-December after French withdrawal amid public budget crisis

France is cutting support for European night trains. Paris–Berlin–Vienna will be suspended in Dec 2025. A huge step back for low-carbon travel.
Calling on @cnrs.fr & @egu.eu to help defend trains as an alternative to flying, including for scientific conferences.

“Transformational” Satellite Will Monitor Earth’s Surface Changes - Eos The mission, jointly operated by the United States and India, will measure minute changes to land, ice, and ecosystems around the globe.

#NISAR will take 90 days to perform commissioning tests & reach its science orbit.

“But as we progress, we’re going to get little peeks behind the curtains...It’s going to be transformational.”
—Alex Gardner, JPL

Liftoff! The NASA-ISRO Synthetic Aperture Radar mission has launched from Satish Dhawan Space Centre. #NISAR will scan the entire globe twice every 12 days to measure changes in Earth’s ecosystems, cryosphere, and land surface.

The paper led by Martin Colledge (@martincolledge.bsky.social) is now out in Geophysical Journal International, “Annual variations in Nepalese seismicity: b-values and seismicity rates”, in collaboration with C. Duverger, A. Schubnel, L.B. Adhikari & L. Bollinger and myself

Annual variations in Nepalese seismicity: b-values and seismicity rates SUMMARY. Seasonal variations in Nepalese seismicity have been reported with varying degrees of confidence. We re-investigate these claims by analysing 20 y

Do monsoon-driven stress changes modulate Himalayan seismicity? We analyze 20yrs of Nepalese seismicity & found no robust annual variation in seismicity rate but statistically significant seasonal modulation of b-values peaking in summer when Coulomb stress is at its lowest
