My work broadly revolves around two themes: understanding intriguing fundamental material properties, fueled by curiosity, and designing materials for targeted applications, driven by technology.
Curiosity driven: Emergent phenomena in materials.
Technology driven: Materials for a sustainable future
Design of excitons: We developed a new computational approach to solve the Bethe-Salpeter equation to capture excitons based on first principles. Using this strategy, we successfully captured the behavior of excitons in moiré materials. See our works at NPJ 2D Materials & Apps. , and Nature Physics.
Discovery of phasons: Two sound-wave like collective excitations in moiré materials that influence electrons in a fascinating way. See our works at Phys. Rev. Research, ACS Nano, and Nano Letters. Originally discovered in quasicrystals, we showed they can be realized and controlled in a broader, more accessible class of materials.
Making better batteries: We are studying key degradation mechanisms in Li-ion batteries and exploring design principles for oxygen-redox in industrial cathodes (ongoing work).
