About

Motivated and Focussed to contribute in the cutting edge research in the field of Mesoscopic Physics of Condensed Matter, and to explore Potential Applications with Societal Values using the Experimental and Analytical skills that I have developed during my professional training.

I am involved in investigation of mesoscopic structure in condensed matter in technologically relevant materials using small-angle X-ray and neutron scattering and scanning electron microscopy.

The primary objective of my doctoral thesis was to understand the mechanism of formation of nanocomposites having hierarchically decorated correlated nanostructure by evaporative self-assembly in contact-free colloidal droplets and the investigation of their novel properties.

I am also responsible for the development and installation as well as utilization of a state-of-the-art facility of Small and Wide-Angle X-ray Scattering beamline (SWAXS-BL18) at Indus-2 synchrotron at RRCAT, Indore, India. My individual contribution in the development program was towards the installation and optical alignment of several important components of the beamline including double crystal monochromator, focusing X-ray mirror, slits, and movable detector stage, and designing customizable sample changers, heating stage etc.

I am Conversant in analyzing Small-angle X-ray and Neutron Scattering data. Skilled in writing mathematical modelling program using PYTHON for the analysis of experimental data. I am also experienced in acquiring images using field-emission scanning electron microscope.

I have developed a graphical user interface (GUI) based data reduction software using PHYTHON language for processing of 2D-frames clubbing, data normalization, transmission estimation and correction, absolute scale conversion, radial and azimuthal averaging of raw Small-angle scattering data both in interactive and batch mode in a user-friendly manner. The software package is tailor-made for processing data obtained from the SWAXS beamline (BL-18) of Indus-2, RRCAT.

I also developed a GUI-based data acquisition software using PYTHON for Medium-resolution Small-angle Neutron Scattering (MSANS) instrument installed at Guide tube laboratory of Dhruva reactor, Mumbai, India.
