Biography

Dr. Jelmy E. J. joined the Department of Polymer Science and Rubber Technology, Cochin University of Science and Technology (CUSAT), in June 2018 as a Postdoctoral Fellow (PDF) under the mentorship of Prof. Honey John. She earned her M.Sc. in Applied Chemistry from the University of Calicut in 2008 and subsequently pursued her Ph.D. at the Department of Chemical Engineering and Materials Science, Amrita University, Coimbatore. Her doctoral research was on the development of polyaniline–carbon nanotube nanocomposites for electromagnetic interference (EMI) shielding and dye-sensitized solar cell (DSSC) applications.

During her postdoctoral tenure at CUSAT, Dr. Jelmy’s research was primarily devoted to the design and development of graphene/conducting polymer nanocomposites targeting environmental remediation and sustainable energy harvesting applications. Her significant contributions in the field of Triboelectric Nanogenerators (TENGs) include the development of novel nanocomposite systems for enhanced charge generation and durability. In parallel, she has worked extensively on functional adsorbent materials for dye removal and CO₂ capture, demonstrating a strong interdisciplinary approach to materials research. Following her postdoctoral research, Dr. Jelmy served as a Project Associate in a DST-funded project at the Inter University Centre for Nanomaterials and Devices (IUCND), CUSAT, where she played a key role in developing wearable and wireless triboelectric sensors for respiratory rate and sleep monitoring applications. This work integrated materials design, sensor fabrication, and self-powered device technology for next-generation healthcare monitoring systems.

Dr. Jelmy is a materials scientist specializing in the design and surface engineering of advanced nanostructured materials for clean energy applications. Since June 2025, she has been a Postdoctoral Fellow under a RUSA-funded project, focusing on MXene-based electrocatalysts for hydrogen evolution reactions (HER). Her research centers on tuning surface chemistry, defect structures, and interfacial charge dynamics to enhance catalytic performance and stability, providing fundamental insights into material–property relationships. With twenty-two international publications and three granted Indian patents, she has made significant contributions to advancing the understanding of 2D materials, functional interfaces, and their role in energy technologies.
