NAVNEETH RAJIV

About

I am a master's student in Materials Science and Engineering at Georgia Institute of Technology specializing in the research and development of materials for energy storage and electronics. I am interested in accelerating technological developments that help in the transition to clean energy and smaller devices. I hail from a small town near Kochi (India).

I have worked with both computational and experimental tools for material design, synthesis, characterization, manufacturing and testing. I have a deep understanding of material modelling, coding (python, Matlab, C++) and statistical tools. In addition, I am trained to handle SEM, XRD, XPS, Optical microscope, Glove box, Potentiostat and Thermal analysis equipments.

I have published 2 conference papers and 1 abstract at International conferences. During undergrad, I was part of the Designers' Consortium, a student club that creates mechanical products to solve pressing challenges in energy, environment, healthcare and industrial sectors. Our projects bagged top positions in competitions and conferences.

Apart from academics, I was the Head of Mettle events and guest lectures team, ex-member of Material advantage and Rotaract club NITT
