    Experimental

Developing a Cold Plasma Laboratory and also Technology Innovation and Startup Facility at IIT Jodhpur. Founded CSIR-CEERI's Incubation-cum-Innovation Hub, Jaipur Centre Facility in the Area of Electronics and Allied Engineering. Also, led plasma devices laboratory activity in the Microwave Devices Area at CSIR-CEERI Pilani and was involved in various experimental plasma research programs. Instrumental in setting Plasma Lab at Birla Institute of Technology, Mesra (Ranchi) Jaipur Centre. Also, developed a modern practical physics lab at BIT Mesra (Ranchi) Jaipur Centre for B.E. students. Played key role in the development of a Plasma Sheath Lab at Centre of Plasma Physics-Institute for Plasma Research, Dispur, Guwahati. Worked on ADITYA (Indian) and ASDEX Upgrade (German) Tokamaks. Learned different active (Langmuir probe, emissive probe, ion energy analyzer etc) and passive plasma diagnostics (UV/visible emission spectroscopy). Got experiences on various scientific equipment e.g. different vacuum pumps, Monochromators, Echelle spectrometer, ICCD, CCD, Boxcar averager, DC/RF power systems, Spectrum Analyzer and some of the corresponding operational softwares.

Theoretical
To interpret own experimental data on plasma sheath (i.e. for two component and multi-component plasmas) a few analytical fluid models have been made. These models have also been numerically treated to explain the resonant behavior of the experimentally observed unstable mode (i.e. sheath driven low frequency Instability, SDLFI). Sheath equivalent electrical circuit model for transient sheath dynamics has also been proposed. For beam wave interaction studies in Plasma Assisted Microwave Wave Source an in-house PIC-FDTD code development was initiated in collaboration with BITS, Pilani and different theoretical studies were carried out at CSIR-CEERI. A few collisional-radiative models based codes like –CHIANTI, ADAS and Helium-CR-mode were setup at IPR, BIT and CSIR-CEERI for spectroscopic data analysis. By using these codes, a few interesting investigations have been carried out to characterize the ECR and ECR+PDC discharge cleaning plasmas in ADITYA (Indian) Tokamak and laboratory plasmas. Estimated the edge electron plasma density, temperature and column-densities of various elements in ADITYA tokamak and ASDEX upgrade tokamak.

Computational
In computational knowledge, have experience to work on DOS & LINUX operating systems as well as knowledge of programming in IDL, Fortran77, and MATLAB. Used WINDOWS, MS office, Microcal Origin, etc. Learned the potential use of ADAS, Helium-CR-mode, CHIANTI, STRAHL, VORPAL and Oopic-Pro codes for spectroscopic data analysis and plasma modelling.
