Julien Meaud

Julien Meaud joined Georgia Tech as an Assistant Professor of Mechanical Engineering in August 2013. Before joining Georgia Tech, he worked as a research fellow in the Vibrations and Acoustics Laboratory and in the Computational Mechanics Laboratory at the University of Michigan, Ann Arbor. 

Dr. Meaud investigates the mechanics and physics of complex biological systems and the mechanics and design of engineering materials using theoretical and computational tools. 

One of his research interests is auditory mechanics. In this research, he develops computational multiphysics models of the mammalian ear based on the finite element method. The mammalian ear is a nonlinear transducer with excellent frequency selectivity, high sensitivity, and good transient capture. The goal of this basic scientific research is to better understand how the mammalian ear achieves these characteristics. This research could have important clinical applications as it could help in the development of better treatment and the improvement of diagnostic tools for hearing loss. It could also have engineering applications, such as the design of biometic sensors. This research is truly interdisciplinary as it includes aspects of computational mechanics, structural acoustics, nonlinear dynamics, biomechanics and biophysics. 

Dr. Meaud is also interested in the mechanics, design and optimization of composite materials, particularly of their response to cyclic loads. Tradtional engineering and natural materials with high damping (such as rubber) tends to have low stiffness. However, the microarchitecture of composite materials that consist of a lossy polymer and a stiff constituent can be designed to simultaneously obtain high stiffness and high damping. Using computational tools such as finite element methods and topology optimization, the goal of Dr. Meaud's research is to design composite materials with these unconventional properties. One of his future goal is to extend the design of these materials to the finite strain regime and high frequency ranges, in order to obtained materials tailored for the targetted application. This research includes aspects of mechanics of materials, computational mechanics and structural dynamics. 

In Dr. Meaud's research group, students will learn theoretical and computational techniques that are used extensively to solve engineering problems in academic research and industry. Students will develop knowledge and expertise in a broad array of mechanical engineering areas. The knowledge that students will gain in computational mechanics, nonlinear and structural dynamics, structural acoustics, dynamics and composite materials could be applied to many domains in their future career.
