Rahul Singh

Doctoral Researcher under the supervision of Dr. H. S. S. Ramakrishna Matte, with over five years of experience in materials chemistry and electrochemical energy systems. My research focuses on precursor engineering for the controlled synthesis of low-dimensional metal oxides, sulfides, and nitrides, with applications in photoelectrochemical systems, lithium- and sodium-ion batteries, supercapacitors, and piezoelectric devices. I also have hands-on experience with gloveboxes, battery testing systems, and electrochemical workstations.

Training graduate student

I got the opportunity to train graduate students (research interns, first-year and second-year PhD students) to carry out the synthesis of nanomaterials, instruments handling and data analysis for energy storage applications.
