Dr. Neogi's research is at the interface between the fields of materials physics and thermal sciences and focuses on theoretical studies of vibrational energy transport in a wide variety of systems using analytical methods and numerical tools. The overall aim is to formulate structure-processing-property relationships (SPPR) that connect nanoscale structure, dictated by methods of fabrication and processing, and thermal transport. Characterisation of SPPR ultimately empowers us to establish the rational design of materials with desired functionality. Specifically, her work entitles (i) characterisation of nanoscale structure and material-specific vibrational properties, (ii) connecting vibrational and electronic properties to thermal transport in nanoscale devices, (iii) tuning the structure-vibrational property interconnection at the nanoscale and thereby controlling macroscale device functionality.
