Research highlight
  • Charge Carrier Dynamics in Photovoltaics
  • Transport Through Nano-Junctions
  • Magnetic and Optoelectronics in Low-Dimensional Materials
 Educational Background/Employment:
  • Ph.D (2016) Material Science, CPMU/TSU, JNCASR, Bangalore, India
  • M.S. (2012) Material Science, CPMU, JNCASR, Bangalore, India
  • B.Sc. (2009) Chemistry, Dept. of Chemistry, Visva Bharati, WB, India
  • Employment:
    • 2018 - Present : Postdoctoral Research Associate, Los Alamos National Laboratory, NM, USA
    • 2016 - 2018 : Postdoctoral Research Fellow, Dept. of Physics and Chemistry, Univ. of Bath, UK

Research Interests:

  • Computational Modelling of Materials for Solar Cells : I am extensively using ab initio methods to study the charge carrier dynamics in lead halide perovskite solar cells. The effect of lattice-dynamics, point and extended defects on optoelectronic and photovoltaic properties of halide perovskites is my another topic of on-going research. I am also investigating the possible route for enhancing the phase-stability by exploring the vast chemical and configurational space of these hybrid perovskite materials.
  • Gamma and X-Ray Detectors : I am also involved in material designing for next generation Gamma and hard X-ray detectors.
  • Nano-materials for Thermoelectrics and Spintronics : Understanding heat, charge and spin transport through magnetic nano-junctions is my another research interest. These are highly important for thermoelectric, spin-caloritronics and digital data-storage applications.
