Dr. Thadhani is Professor and Associate Chair in the School of Materials Science and Engineering. He also holds a joint appointment in the Woodruff School of Mechanical Engineering.

Research Interests
Synthesis, processing, and fabrication of bulk nanocrystalline, metastable, and non-equilibrium alloys, ceramics, and composites with unique structural, energetic, magnetic, and thermoelectric properties through dynamic powder consolidation, and shock-induced phase transformations and chemical reactions
High-strain-rate deformation and failure studies through time-resolved measurements and numerical simulations in metals, ceramics, and composites

Design, fabrication, and impact studies of energy-releasing and energy-absorbing metallic, ceramic, and composite materials
After completing two years of postdoctoral research at Caltech, Dr. Thadhani spent 6 years at his alma mater at New Mexico Tech, where he managed the new-materials programs in the Center for Explosives Technology Research. He joined the faculty in the School of Materials Science and Engineering at Georgia Tech in September, 1992. He has been involved in research and teaching in high-strain-rate mechanical properties, deformation and strengthening mechanisms, phase transformations, and processing of nanocrystalline and metastable materials with structural, energetic, and functional properties. He uses impact -generated dynamic high-pressure shock-compression, self -sustaining combustion processes, and mechanical alloying by ball milling to respectively produce very high, intermediate, and low rates of chemical reactions and/or phase transformations, for synthesis of novel/non-equilibrium phases and nanocrystalline structures. His high-strain-rate laboratory includes an 80-mm diameter single-stage gas-gun to perform impact experiments at velocities of 100 to 1100 m/s with instrumentation to monitor shock-initiated events with nanosecond resolution employing piezoelectric and piezoresistive stress gauges, velocity interferometry, and high-speed digital imaging, combined with the ability to recover impacted materials for post -mortem microstructural characterization and determination of structural and functional properties.

His current research projects include (a) dynamic shock consolidation of powders for fabrication of bulk nanocomposite exchanged-coupled permanent magnets with high energy products (ONR); (b) design, processing, characterization and evaluation of structural energetic materials (based on intermetallics, ceramics, thermites, and polymer-composites) and including determining their pressure-volume compressibility characteristics and constitutive equations (AFOSR, AFRL, and NSWC); (c) shock processing and high strain rate mechanical properties of bulk metallic glasses and their composites (ARO); and (d) development and validation of constitutive equations for high-strain-rate mechanical property characterization of tantalum and other bcc metals (LLNL). Dr. Thadhani’s research group includes one post-doctoral fellow, seven graduate students, and five undergraduate students. He has graduated 20 Ph.D. and M.S. students, who are working in DoE and DoD national laboratories, universities, and industries.
