Current fellows

Anxo Farina Biasi (since September 2022)
Anxo received his PhD in 2019 at the University of Santiago de Compostela (Spain) under the supervision of Javier Mas ; and did a first postdoc at the Jagiellonian University (Poland), under the project "Dynamics in spatially confined Hamiltonian systems" leaded by Piotr Bizon.

He is a theoretical physicist working in the interface between mathematics and physics. His research interest focuses on the dynamics of nonlinear evolution equations, studying more specifically turbulence and singularity formation. This research has a broad spectrum of applications ranging from Bose-Einstein condensates, and fluid dynamics, to black holes formation. He published several articles on these topics :

Cyrille Solaro (since August 2021)
Cyrille Solaro obtained his PhD in atom interferometry in 2016 under the supervision of F. Pereira dos Santos at the French metrology institute (LNE-SYRTE, Paris Observatory), where he came to like metrology as a way to test fundamental physics. He has since then continued to develop his interest for high precision measurements in atom interferometry as well as in ultra-precise spectroscopy of atoms, ions and molecules.

During his postdoc at Aarhus University (Denmark) he demonstrated, in collaboration with the group of Michael Drewsen, the metrological relevance of using frequency-comb lasers to perform high-precision stimulated Raman spectroscopy, and to search for new physics beyond the standard model.

This leads him to explore with his JRC project the possibilities of using frequency-comb lasers to perform atom interferometry. This project will eventually open up new possibilities in metrology, sensing of gravito-inertial effects and tests of fundamental physics.

Cyrille joins the atom interferometry team at LKB, collaborating with Saïda Guellati-Khelifa.

Antonio Costa (since September 2020)
Antonio Carlos Borges Santos da Costa joined our JRC team for his first postdoctoral position.

Antonio obtained his PhD in 2020 under the supervision of Greg Stephens at Vrije Universiteit Amsterdam (Netherlands). He worked on the physics of animal movement behaviour, studying organism scale movements. He uses physics inspired approaches from statistical mechanics and dynamical systems theory, as well as information theory and statistical inference.

He collaborates with the theoretical neuroscience and biophysics team members :
