Dr. Ghosh is a Post-Doctoral Research Associate at City, University of London. He is working in a project funded by the Natural Environment Research Council (NERC), UK. He received his PhD degree in Photonics from the School of Mathematics, Computer Science, and Engineering (SMCSE), City, University of London in 2018 where he worked on the design and optimisation of integrated photonic sensing devices. He obtained his M.Tech. degree (as the 1st Rank holder) and B.Tech. degree (as the 1st Rank holder) in Optics and Optoelectronics from University of Calcutta, India in the years of 2014 and 2012, respectively.

Dr. Ghosh's research interest focuses on the design of optical fibres, dielectric and plasmonic waveguides, and their applications in bio and chemical sensing. His expertise lies in numerical methods for the assessment of optical systems such as Vectorial Finite Element Method (VFEM) and Finite Difference Time Domain (FDTD).
