He holds MSc and PhD degrees in mechanical engineering from the Georgia Institute of Technology and a PhD degree in engineering mechanics from the University of Lorraine in Metz, France. Dr. Haberman has worked extensively on the modeling and characterization of composite materials as well as the multiobjective design of acoustical materials. Currently, his focus is on the analysis, design, and testing of composite materials, metamaterials, and structures to absorb acoustical and vibrational energy using negative stiffness. He is also conducting research on passive and active materials that enable nonreciprocal wave phenomena in elastic and acoustic media.
