Here is a list of active scientific collaborations:

• Prof. Richard J. Cogdell from Glasgow University (UK). Long-standing collaboration on ultrafast pump-probe spectroscopy of carotenoids and light-harvesting complexes from photosynthetic bacteria.

• Prof. Tom Moore and Ana Moore from Arizona State University (USA). Excited-state dynamics and energy transfer efficiency of artificial antenna complexes.

• Prof. Hideki Hashimoto from Osaka City University (Japan). Pump-probe spectroscopy and microscopy of modified photosynthetic units from purple bacteria.

• Prof. Harry Frank from University of Connecticut. Ultrafast dynamics of carotenoids.

• Prof. Pierre-Michel Adam from Troyes University (France) on plasmon dynamics of gold nanoparticles.
• Prof. Marie-Paule Pileni from Université Pierre et Marie CURIE (Paris, France). Coherent phonons and ultrafast dynamics in nanocrystals and self-organized supra-crystals.

• Dr. Marco Garavelli (Università di Bologna, Italy) on theoretical and computational quantum-mechanical simulations of photo-chemical reactions.

• Dr. Tullio Scopigno from Università di Roma – la Sapienza (Italy). Picosecond acoustics and coherent Raman Spectroscopy/Microscopy.

• Dr. Jérémie Léonard from Université de Strasbourg (France). Isomerization dynamics.

• Center for Nano Science and technology (CNST) at the Istituto Italiano di Tecnologia (IIT), headed by Prof. Guglielmo Lanzani. I am “embedded” in the center (located in Milano, very close to the Politecnico) and I collaborate with the ultrafast spectroscopy group in the “Energy” platform, whose mission is Solar Energy Harvesting (novel sensitized and hybrid PV cells).
