I completed B.Sc. and M.Sc. in physics from Visva Bharati, Santiniketan and joined Saha Institute of Nuclear Physics, Kolkata as a research fellow for Ph.D. After my Ph.D., I carried out post-doctoral research at National Institute for Materials Science, Tsukuba, Japan, at Institute of Physics (IOP), Bhubaneswar, and at National Institute for Science Education and Research (NEISER), Bhubaneswar. I joined the physics department of Sripat Singh College in 2019.
I am involved in teaching and mentoring of students pursuing under-graduate studies in physics. I also teach post-graduate students of physics as guest college_faculties.
I am also pursuing research in collaboration with IOP, Bhubaneswar and NEISER, Bhubaneswar. I research involves experimental studies on growth and properties nanoscale materials and nanostructures on materials surface. My particular interest is use of ion beam for growth of nanostructures.Â
I have more than 35 publications in international SCI journals in the field of my research. I have also completed one SERB project. Recently, I received a patent as a member of a team on application of nanoscale TiO2 for wastewater treatment.
