Research Interests

  • Electrochemical energy storage (rechargeable Li/Na-ion batteries, Li-S batteries etc.) – design, synthesis, and in-situ/operando structural characterization of electrode materials, solid state electrochemistry
  • Applications of advanced spectroscopic techniques (such as, x-ray absorption, x-ray Raman) – local structural characterization
  • Solid electrolytes (glasses/polymer/crystalline) – carrier and structural dynamics; all solid-state batteries
  • Multifunctional metal oxide thin films -synthesis, characterization
