I am Barani Kumar from Perambalur, Tamil Nadu, India. I am an M.Sc Physics graduate eager to pursue a Ph.D. in physics. I have a deep interest in quantum mechanics, and my final year research project focused on the Hydrogen and Oxygen Evolution Reactions using DFT. Through this course, I expect to gain a strong foundation in materials science and DFT. I believe this course will contribute significantly to my future research.
