Area of research: Plasma waves, Strongly coupled Plasma,Nonlinear phenomena in Plasma
Physics of strongly coupled plasma (SCP) has a great impact in the field of dusty plasma because of its possible applications in astrophysical situations and also in industries. The thermodynamic behaviors of SCP are strongly dependent on the nature of electrostatic interactions among the dust grains and also with the background plasma. Plasma waves are an inter-connection between particles and fields propagating in periodic manner. The nonlinearities in plasmas contribute to the localization of waves, leading to different types of fascinating nonlinear coherent structures such as solitary wave profiles, double layers, shock wave profiles, vortices, etc., which are important from both theoretical and experimental points.
Area of research: Interaction Mechanisms in Complex plasma, phase behavior and transport property of softly interacting system of particles
The interactions between constituents of a many particle system is of fundamental importance. An accurate understanding on the nature and type of forces existing between particles can help us diagnose certain important properties like phase behavior, diffusion etc. Molecular Dynamics Simulation may serve as an useful tool for investigating these properties. The feasibility of high magnetic field in experiments (MDPX in Auburn University, DPD in Kiel University) facilitates the study on system behavior in presence of strong magnetic field. The experimentally relevant research models are simulated with the analytically derived interaction potential to understand the dynamics of charged dust grains. A comprehensive analysis on the properties of dust grains may help in addressing issues relating to dust plasma interaction in fusion reactors which are operated at high magnetic
Area of research: Study on various phenomena in Laser-Plasma interactions
The interaction of an intense laser field with plasma leads to various interesting phenomena, which finds immense applications in a variety of science fields, including Material, Life, Nuclear science and technology etc. One of the major motivation of the study of laser-plasma interactions is its application potential in the Inertial Confinement Fusion (ICF) to produce clean and sustainable energy. Computer simulations serves as a great tool in understanding the mechanisms involving the synergy of highly intense laser with matter, which are sometimes difficult through experiments. Using Particle in Cell (PIC) simulations, an investigation on various mechanisms of ion acceleration are attempted, which may help in the optimization of the energetic ion beams, which are generated as a result of the interaction of high power laser with matter.

Area of research: Three dimensional (3D) particle-in-cell (PIC) simulation of High-Intensity Laser-Plasma Interactions: Proton acceleration, Magnetic field generation and Second harmonic generation.
With the recent advances in high power lasers based on the invention of chirped pulse amplification (CPA) and advanced femtosecond techniques, the interaction of plasma with high intensity laser fields has become possible. The nonlinear interaction of laser pulses with plasmas leads to a wide range of applications such as laser plasma based accelerators, X-ray laser, inertial confinement fusion (ICF) and harmonic radiation generation. Laser-plasma accelerators have been proposed as a next generation of compact accelerators because of the huge electric fields produced (> 100 GV/m). Generation of magnetic fields of the order of 100 MG has been observed experimentally and it is important to study them as they have a remarkable effect on high-energy electron flow. Harmonics generated in these interactions contains more number of photons as compared to the fundamental and hence they serve as an excellent tool for laser plasma diagnostics, especially to diagnose warm and hot dense matter.
Research Interest : Coulomb crystallization in dusty plasma, Interaction mechanism in dusty plasma, Phase transition of dusty plasma.
