Biography:

Dr. Vivek Kumar Verma has completed his B.Sc. and M.Sc. from University of Lucknow, India. He has done his PhD in Physics at the age of 29 years from University of Delhi and National Physical Laboratory (CSIR), India. In 2009 he has joined Department of Physics, Hindu College, University of Delhi as an Assistant Professor. Dr. Vivek Kumar Verma is lifetime member of Magnetic Society of India. He has supervised many Ph.D. students. His area of interest are nano magnetic materials, EMI shielding, ferroelectric materials and energy materials. He has published more than 55 papers in reputed journals and serving as an active member of scientific society. Currently working as an Associate Professor in department of Physics, Hindu College, Delhi University, India.

      The thesis work was on the development of the high quality, cost effective and low loss ferrites for microwave and power applications. EMI shielding applications of soft and hard ferrites and their composites with conducting polymers.

Area of reasearch- Magnetic nano-materials, Spintronics materials and multiferroic systems.
