Professional skills
In summary
I have experience in the development of experimental setups; including system design, purchasing and setting up, interfacing, documentation and use. I have developed magneto-optical imaging (MOI) and scanning Hall probe microscopy (SHPM) techniques. These local probes have been used to characterize both superconducting and magnetic structures. In the former case, the motivation is to better understand vortex matter and optimize pinning mechanisms in superconductors. The latter is contributing to a wider study on the development of micro flux sources for applications in biology and medicine. I also have experience in bulk magnetization measurements as well as transport measurements and worked on the development of micro-magnet arrays. Throughout my career I have worked well with colleagues and helped in the supervision of younger scientists.

LabVIEW
I am a Certified LabVIEW Associate Developer (CLAD) (current certificate valid till February 01, 2026), and excel in LabVIEW programming for instrument control, automation of experiments, image and data analysis etc.
Advanced LabVIEW programming for instrument control, automation of experiments, image and data analysis etc. I have been learning and using LabVIEW since my M.Sc. days. Throughout my research career, I have developed of PC interfaces as well as programs for data analysis for all my experiments: MOI at IIT Kanpur, SHPM at Institut Néel, transport measurements at TIFR, Institut Néel and University of Liège, and more.
Furthermore, apart from being familiar with commercial image analysis software, I have also developed custom image analysis routines using IMAQ / Vision Development Module in LabVIEW, which gives the flexibility of detailed image analysis while maintaining quantitative information, which is crucial, and rather difficult when using third party software.
I have co-developed "Virtual Laboratory: Oscillations", an online portal for virtual experiments in physics, using LabVIEW. This is under a project from the Ministry of Human Resource Development (MHRD), India, whose PI is Prof. Satyajit Banerjee. (Other developers are Pabitra Mandal and Prof. Satyajit Banerjee). The portal is hosted at: https://iitk.ac.in/oscillations/.
