Following a 2-year appointment as Postdoctoral Research Fellow at the University of Michigan, Ann Arbor (Mechanical Engineering), former PhD student Othman Oudghiri-Idrissi has joined the Maseeh Department of Civil, Architectural and Environmental Engineering at the University of Texas at Austin as Assistant Professor in August 2024.
On March 5, 2024, Prof. Guzina gave a Meta-MAT lecture “Plug-and-play paradigm for the analysis of scattering by layer-cake periodic systems”. A video recording of the lecture is available here.
Buno Lombard (CNRS – Laboratoire de Mécanique et d’Acoustique) and Bojan Guzina are co-organizing a CISM course on Wave Motion in Heterogeneous Media: Analysis, Modeling and Design. Speakers will include Guillaume Bal (University of Chicago), Rémi Cornaggia (Sorbonne Université – Institut Jean Le Rond d’Alembert), Richard Craster (Imperial College London), and Dennis Kochmann (ETH Zurich). The short course will be held June 19-23, 2023. More details and registration available at https://www.cism.it/en/
On May 16, 2022, Prof. Guzina gave the inaugural EMI Elasticity Committee Distinguished Lecture in the Department of Civil and Environmental Engineering, University of Michigan, Ann Arbor.
Following a 2-year postdoctoral appointment at Laboratoire de Mécanique et d’Acoustique (Marseille, France) and a in at the University of Minnesota, Remi Cornaggia, a former PhD student co-advised with Marc Bonnet (through the co-directed PhD program with Ecole Polytechnique), has joined Institut Jean Le Rond d’Alembert, Sorbonne University, as Assistant Professor in November 2020.
Following a 2-year postdoctoral appointment at the University of Michigan (Department of Mathematics), Shixu Meng, a former IMA Post-doctoral Fellow, has joined the Institute of Applied Mathematics, Chinese Academy of Sciences, as Assistant Professor in September 2020.
Following a 4-month postdoctoral position in at the University of Minnesota, Fatemeh Pourahmadian , a former PhD student co-advised with Joseph Labuz, has joined the Department of Civil, Environmental and Architectural Engineering, University of Colorado at Boulder, as tenure-track Assistant Professor in January 2017.
This work [59] illustrates the pursuit of a formal two-scale homogenization approach to extract the mean wave motion in bi-periodic solids, including the effect of incipient dispersion. We show that such low-frequency expansion leads to a family of fourth-order PDEs (resembling the phenomenological models of gradient elasticity) whose coefficients derive explicitly from the microstructure.
In this collaborative study [62] with Ralph Sinkus and Sverre Holm, we demonstrate by experiment and theory the ability of elastic waves to sense random microstructures that are three decades smaller in size than the probing wavelength. Our analysis deploys an extension of the O’Doherty-Anstey (ODA) theory and the fact that interparticle distances in random monosized distributions may exhibit fractal character.
