Dr Ghosh completed his undergraduate studies at St Xavier's College, Kolkata, followed by a Master's degree in Chemistry from the Indian Institute of Technology, Kanpur. He then pursued his doctoral research at the Cavendish Laboratory, University of Cambridge, where he specialised in ultrafast spectroscopy. As a Title A Research Fellow at St John's College he is leading independent research in ultrafast spectroscopy and microscopy, with a focus on applications in optoelectronics.
His research focuses on how light interacts with matter on extremely fast timescales - down to millionths of a billionth of a second (femtoseconds). He studies a wide range of advanced materials: those that illuminate phone screens, absorb sunlight in solar cells, or emit light for live cell imaging. His work also explores how light can be precisely manipulated to accelerate or slow down chemical reactions, opening pathways to new technologies in physics, energy, and sustainable chemistry.
