Pratik Sen

Pratik Sen is a Professor in the Department of Chemistry at the Indian Institute of Technology Kanpur, specializing in fluorescence and ultrafast spectroscopy. He has been a faculty member at IITK since 2008.

Education

• PhD (2006), IACS Jadavpur
• M.Sc. (2001), Visva-Bharathi University

Research Interests

Prof. Sen’s laboratory focuses on mechanistic investigations of photo-induced processes in real time, covering:

• Ultrafast Laser Spectroscopy
• Even-Order Nonlinear Spectroscopy
• Single-Molecule Spectroscopy
• Dynamics of Biological Macromolecules (proteins, DNA, lipids)
• Nanoparticles and Interfaces
• Confined Environments

The group employs femtosecond transient absorption, fluorescence up-conversion, TCSPC, steady-state fluorimetry, and custom-built fluorescence correlation spectrometers to probe excited-state relaxation dynamics from femtoseconds to nanoseconds.

Selected Publications

His recent publications (2011–2013) reveal a strong emphasis on elucidating excited-state pathways of biologically and materially relevant chromophores, exploring protein stability, solvent effects, and interfacial phenomena.

Awards & Fellowships
