Giovanni Batignani

Giovanni Batignani is currently an Associate Professor at the Department of Physics, Sapienza University of Rome, within the Faculty of Mathematical Sciences. His academic career includes a prior tenure as a Tenure Track Researcher in the same department. He specializes in ultrafast spectroscopy, particularly femtosecond stimulated Raman techniques, and nonlinear optical phenomena in materials. His research focuses on molecular dynamics, condensed matter physics, and the development of advanced spectroscopic methods for studying excited-state processes in molecules, antiferromagnets, and nanomaterials like graphene and transition metal dichalcogenides.

Major research interests include:

• Ultrafast time-resolved spectroscopy
• Raman scattering (coherent, stimulated, and transient)
• Energy transfer dynamics in molecular systems
• Light-matter interactions in extreme conditions
• Applications of machine learning in spectroscopic data analysis

His publications emphasize innovations in femtosecond techniques, such as chirped pump-probe spectroscopy and 2D broadband Raman methodologies, with notable contributions to understanding excited-state molecular geometries and vibrational relaxation in heme proteins. Research projects include developing flowing liquid jet nozzles for high-resolution pump-probe experiments and exploring the potential of EuPRAXIA@SPARC_LAB facilities for advanced spectroscopic techniques.

Notable collaborations involve studies on perovskite materials, antiferromagnetic dynamics, and graphene heterostructures. His work bridges fundamental physics with applications in material science and biophysics.
