Current research interests

My specialty is mixing geological observations and experimental geophysics. Mostly working on the mantle rheology either in the lab (Ferrand & Deldicque, 2021; Ferrand, 2019a, 2019b; Ferrand et al., 2018; Ferrand et al., 2017; Gasc et al., 2017), on the field (Ferrand et al., 2018) or via geophysical methods (Ferrand, 2022?; Craiu et al., 2022?; Mao et al., 2021; Ferrand & Manea, 2021; Ferrand, 2020a, 2020b; Kita & Ferrand, 2018), I also took part in deformation experiments on carbonates (Baud et al., 2017) and high-grade oceanic rocks (Incel et al., 2017). I focus as much as I can on the comparison between natural and laboratory features and processes (Ferrand et al., 2021; Kita & Ferrand, 2018) and the significance of laboratory experiments in the interpretation of geophysical data (Ferrand, 2022?, Ferrand & Manea, 2021; Ferrand, 2020a, 2020b; Ferrand,2019a, 2019b).
