Buffalo, New York, United States
I am a Postdoctoral Researcher at the University at Buffalo (ILPB) working at the intersection of photophysics, nanomaterials, and optical spectroscopy. My research focuses on understanding excited-state dynamics, energy transfer mechanisms, and structure–property relationships in functional materials for photonic and imaging applications. I specialize in lanthanide-doped nanomaterials, X-ray–excited optical luminescence (XEOL), and high-temperature ceramic systems such as HfO₂ and HfB₂. My work integrates wet-chemical synthesis with advanced characterization techniques, including steady-state and time-resolved spectroscopy (TCSPC), PXRD, SEM, TEM, and FTIR, to investigate photophysical behavior and material performance. During my Ph.D. at IIT Delhi, I worked on soft matter systems, particularly reverse micelles, to understand confined water dynamics and interfacial behavior. I developed mechanistic insights into how interfacial flexibility governs nanostructure growth and demonstrated that hydration dynamics can serve as a probe for nanoscale processes. My postdoctoral research further expanded into photonic nanomaterials, including Z-scheme and type-II nano-heterostructures, bioinspired energy transfer systems, and lanthanide-based scintillators for photon conversion and imaging applications. I am particularly interested in bridging fundamental photophysics with applications in X-ray imaging, optoelectronics, and extreme-environment materials. Actively seeking postdoctoral and research scientist opportunities in photophysics, nanomaterials, optical spectroscopy, and functional materials.
