Dr Surajit Kayal obtained his Bachelors (BSc Honours) in Chemistry from Calcutta University and MSc in Chemistry from IIT Delhi. After MSc, he taught at RGUKT Hyderabad as a Lecturer. He secured 29th rank in CSIR and obtained his PhD from the Indian Institute of Science, Bangalore, under the mentorship of Prof Siva Umapathy. His thesis involves the development of ultrafast stimulated Raman experimental setup and applying it to various chemical problems. After his PhD, he joined the University of Nottingham, UK as a Postdoctoral Fellow, where he worked with Prof MW George and Prof Sir Martyn Poliakoff on time-resolved Infrared Spectroscopy. Dr Kayal returned to India in 2022 and worked for Elsevier as an Associate Scientific Editor, before joining Krea University in 2023.

 

Research

Dr Surajit Kayal’s research interest is in the area of time-resolved spectroscopy, especially time-resolved vibrational spectroscopy. He is very much interested in applying this structure specific tool to understand excited state chemical processes in real-time.
