Dr. Mishra is working as an Assistant Professor in the Department of Physics, IIT (BHU). His research interest is mainly focused on quantum and classical spin systems.  He completed Ph.D. from Department of Physics, IIT Kanpur, under the supervision of Prof. V. Subrahmanyam where he worked on the dynamics of antiferromagnetic nanoparticles using numerical and analytical approaches. After Ph.D., he spent one year at IIT Madras working with Prof. Arul Lakshminarayan and worked on the problems related to entanglement in Quantum spin systems. Subsequently, he worked as Wissenschaftliche Mitrebiter (Scientist) at the Institute of Physics, Martin Luther University Halle-Wittenberg, Germany in the Non-equilibrium many body systems group of ProfJ. Berakdar.
