Dr. Ravi Kumar Venkatraman

Post-Doc Researcher, CIPR

He is currently a postdoctoral researcher at CIPR, CPG, KFUPM. His research interests include ultrafast spectroscopy in liquid solutions and understanding the influence of solvents on photochemical pathways. To corroborate his experimental results, he uses computational techniques like Density Functional Theoretical calculations and Molecular Dynamics & Simulations. He received his PhD from the Indian Institute of Science, Bangalore, India (2017). His PhD thesis work was adjudged as the Best Thesis in National Laser Symposium held in Mumbai (2017). He was awarded the prestigious Newton International Fellowship in 2017 for his first postdoctoral work at the University of Bristol, United Kingdom. Before he joined CIPR he also worked at world-class Ultrafast Spectroscopy labs at the University of Texas at Austin, USA & the University of Sheffield, UK. He has peer-reviewed >75 research articles in various reputed journals like Nature Communications, Physical Chemistry Chemical Physics, RSC Advances, Journal of Physical Chemistry and more. He has also chaired a session at the RSC Spectroscopy& Dynamics Group Meeting (2022) and was a local organizing committee member of 2 international conferences.
