Dr. Jelmy E.J.

Post-doctoral scholar

Biography

Dr. Jelmy E.J. joined the Department of Polymer Science and Rubber Technology in June 2018 as a Postdoctoral Fellow (PDF) under the mentorship of Dr. Honey. She received M.Sc. in Applied Chemistry from the University of Calicut in 2008. Then, she moved to Coimbatore, Tamil Nadu, to pursue doctoral studies in the Department of Chemical Engineering and Materials Science at Amrita University Coimbatore, where she worked under Dr. Nikhil. K. Kothurkar for the development of ‘polyaniline-carbon nanotube nanocomposites’ for Electromagnetic Interference Shielding and Dye- Sensitized Solar Cell applications.

During her tenure as a PDF within the Department of Polymer Science and Rubber Technology, CUSAT, her research efforts centered on advancing graphene/conducting nanocomposites for environmental and energy applications. Her research in Triboelectric Nanogenerators and developing adsorbents for dye and CO 2 has yielded significant outcomes for Dr. Jelmy E.J. In the area of triboelectric nanogenerators, she boasts five publications in international journals, along with two granted Indian patents and one filed Indian patent to her credit. Being with the Nanomaterials group of Prof. Honey, she is currently working as a project associate in a DST-funded project to develop wearable wireless triboelectric sensors for respiratory rate and sleep monitoring applications at IUCND, CUSAT. She has recently delved into the field of MXene-based systems, particularly concentrating on electrocatalytic hydrogen evolution reactions.
