About Me:

My primary research interests are photon interaction studies mainly Compton scattering studies and Compton profiles. I have also worked on Spin-injection studies on Fe3O4 based heterostructures and magnetoimpedance studies in (111) oriented Fe3O4 thin films. I worked in Regional Institute of Education (RIE) during 2018-2019. I have joined The National Institute of Engineering (NIE) in 2019. I have completed B. Sc.  from Bangalore University securing 3rd rank and M. Sc. from University of Mysore securing 1st rank in Physics with four gold medals and two cash prizes.  I received DST- INSPIRE Fellowship to pursue my doctoral studies. I have publications in international peer reviewed journals such as Europhysics letters, The European Physical Journal Plus, Radiation Physics and chemistry, Nuclear Instruments and Methods in Physics Research A. In addition, I have participated and presented papers in many national and international conferences and secured best oral presentation at NCRP-2017 and CMPA-2017 conferences
