The Biomechanics team at the MSME laboratory (Université Paris-Est Créteil) is developing a research partnership with the Paris Cardiovascular Research Center to create a numerical twin of a high-throughput assay for testing the effects of drugs on cardiac tissue. M. Caruel, the project leader in the Biomechanics group, is seeking a highly motivated student to con- tribute to the development, calibration, and validation of this numerical twin in close collaboration with members of PARCC. The model is based on an existing formulation, which will need to be adapted to the experimental conditions and implemented numerically. Available experimental data will be used for model calibration and validation. The student may also participate in the experimental work. The internship will be based at MSME in Créteil, with regular meetings at PARCC in Paris.
