Conducted original research in the laboratory for active materials and smart structures (LAMSS). Proactively involved in SHM and active sensing related projects. Performed theoretical developments for modeling thickness mode E/M impedance spectroscopy (EMIS) of PWAS; developed Proof mass PWAS (PMPWAS) transducer for tuning wave modes; developed analytical EMIS model of Bio-PWAS; and developed a guided wave technique in welded thick structures by the weld guided quasi-Rayleigh wave.
