S. Athithya is a post doctoral fellow working in emerging field of dye sensitized solar (DSSC), thermoelectric, photocatalysis and synthesising highly porous functional materials. She joined in Department of Nanoscience and Nanotechnology, SRM Institute of Science and Technology (formerly known as SRM University) in July 2018 as a doctoral student in Functional Materials and Energy Devices (FMED) laboratory. She completed her master’s in Nanoscience and Nanotechnology (Physics) form Bharathiar University, Coimbatore and bachelor’s in Physics from Lady Doak College, Kamaraj University, Madurai. She gained the knowledge about tailoring ZnO material from her internship in Indian Institute of Technology (Indore). In FMED laboratory, she is experienced in developing DSSC and handled IV and IPCE instruments. Her research work focus on tunning the porous TiO2 materials for development of high-performance dye sensitized solar cell.
