Avnee Chauhan, PhD.

Dr. Avnee Chauhan is a materials scientist working in the field of advanced ceramic materials, with a special focus on high-entropy oxides, rare-earth-based functional ceramics, defect chemistry, ionic/electronic transport, optical properties, and energy-related applications. Her research involves the synthesis, processing, and characterization of multi-cation oxide ceramics, and rare-earth high-entropy oxide systems. Her work focuses on understanding the relationship between composition, crystal structure, oxygen vacancies, phase stability, sintering conditions, and functional properties. She has experience in solution combustion synthesis, sol-gel/citrate routes, spark plasma sintering, ultrafast high-temperature sintering, reactive sintering, and cold sintering. Her characterization expertise includes XRD/Rietveld refinement, Raman spectroscopy, SEM/EDS, TEM, XPS, UV-Vis-NIR spectroscopy, photoluminescence spectroscopy, BET analysis, and electrochemical impedance spectroscopy.

Current research interests include:
• High-entropy oxide ceramics for optical, photocatalytic, and electrochemical applications
• Defect-mediated ionic transport in CeO₂-based high-entropy oxides
• Oxygen vacancy engineering in multi-cation oxide systems
• Transparent and translucent rare-earth high-entropy ceramics
• Advanced sintering methods for functional oxide ceramics
