I'm interested in a family of complex materials that were usually viewed as crystals in the field, but exhibit both glass and crystal properties. I call them glass-crystal dual materials, and my PhD thesis is mainly about phonon/electron transport within them. The interplay of disorder, quantum effects, disparate scales, and dimensionality has amazed and entertained me for years. We've demonstrated intriguing physics when dimensionality and scale reduces, we have revealed the competition between classical drifting and quantum interference in metamaterials, and most recently, we've explored the disorder-induced dispersion anti-crossing/hybridization and local resonance blocking in disordered materials (glasses and mixed).
