Biography
Sandrine Brochard is a professor at the University of Poitiers in France and research staff member at the department of Physics and Mechanics of Materials at the PPRIME Institute, in the Defect Physics and Plasticity team. She received her Ph.D. in Materials Science from the University of Poitiers in 1998. Since then, she has undertaken post-doctoral research at the Physics Department at the University of Reading in the UK, and she has been a visiting scientist at the Department of Condensed Matter Physics at the Autonomous University of Madrid.
Her current research focuses on the elementary mechanisms of plasticity in nanoscaled metals, with a special emphasis on the role of surfaces and interfaces, using atomistic simulations.
She is currently an associate editor for the European Physical Journal Applied Physics (EPJ AP).
