Research overview

I am a research fellow at the School of Physics and Astronomy, University of St Andrews, UK, working on the EPSRC Project Rydberg Polaritons in Cu2O microcavities (EP/S014403/1) since November 2019 with Dr. Hamid Ohadi at the Quantum Fluids of Light group. I am also a principal investigator to the Research Incentive Grant (RIG009823), from the Carnegie Trust for the Universities of Scotland, working on quantum confined Rydberg excitons of cuprous oxide. During the earlier period from November 2015 to 2019, I worked on the EPSRC project Hybrid Polaritonics (EP/M025330/1) with Prof. Ifor Samuel and Prof. Graham Turnbull at the Organic Semiconductor Centre. In 2015, I worked at the Ultrafast spectroscopy group with Dr. Tersilla Virgili and Prof. Giulio Cerulllo at Politecnico di Milano. Earlier I graduated in 2009 with Masters in Physics from Sri Sathya Sai Institute of Higher Learning, Anantapur, India. I then joined as an early stage researcher at the Dipartimento di Fisica, Politecnico di Milano, Milan, Italy as part of the Marie Curie ITN-FP7-PEOPLE Project ICARUS (237900) and obtained a Ph.D. degree in 2014.

My current interests involve fabrication and engineering semiconductor and plasmonic materials towards understanding their properties using a wide range of spectroscopic studies for applications in optoelectronics. Materials of interest are carbon nanotubes, inorganic semiconductor and plasmonic nanoparticles, liquid crystals, perovskites, and a wide range of organic semiconductor materials. Fabrication techniques of interest are thermal evaporation, RF magnetron sputtering, spin coating, chemical vapour deposition and focused ion beam etching. Spectroscopy techniques of interest are ellipsometry, Raman spectroscopy, scanning electron microscopy, photoluminescence and amplified spontaneous emission, time-correlated single photon counting, streak camera, X-ray diffraction, Fourier imaging spectroscopy, interferometry, cryogenic spectroscopy, femtosecond transient absorption and 2D electronic spectroscopy.
