Rate My Professor Romain Meyrand

Dr. Romain Meyrand is an Honorary Research Fellow in the Department of Physics at the University of Otago, where he joined the Astrophysical Plasmas and Fluids group in 2019. He completed his undergraduate degree in physics at Paris-Saclay University and earned his PhD in 2013 from Paris-Sud University (Paris XI), under the supervision of Sébastien Galtier, with a thesis titled 'Turbulence à hautes fréquences dans le vent solaire: Modèle phénoménologique et simulations numériques,' focusing on space plasma turbulence. Following his doctorate, Meyrand held postdoctoral positions at École Polytechnique and Paris Observatory. In 2015, he received a Marie Skłodowska-Curie Global Fellowship to conduct research at the University of California, Berkeley. At Otago, he was awarded a Marsden Fast-Start grant in 2020 to support his work.

Meyrand's research specializes in space plasma turbulence, particularly the mechanisms driving heating and dissipation in the solar wind. His contributions include theoretical and numerical studies of Alfvénic turbulence, switchback formation, and electron-ion heating partitions. Key publications include 'In-situ switchback formation in the expanding solar wind' (ApJL, 2020, with J. Squire and B.D.G. Chandran), 'High-frequency heating of the solar wind triggered by low-frequency turbulence' (Nature Astronomy, 2022, with J. Squire et al.), 'Fluidization of collisionless plasma turbulence' (PNAS, 2019, with A. Kanekar et al.), 'On the violation of the zeroth law of turbulence in space plasmas' (Journal of Plasma Physics, 2021, with J. Squire et al.), and 'Spontaneous chiral symmetry breaking of Hall magnetohydrodynamic turbulence' (PRL, 2012, with S. Galtier). These works, published in leading journals, have advanced understanding of collisionless plasma dynamics in astrophysical environments, with his research cited over 1,300 times. Meyrand collaborates internationally with institutions including Princeton Plasma Physics Laboratory and NASA missions like Parker Solar Probe.
