The advent of ultrashort (femtosecond) light pulses has unlocked our ability to probe the early events of light-matter interactions within complex systems, ranging from (bio)-molecules to nanostructures and solids. Ultrafast spectroscopies with different degrees of sophistication have been developed, enabling the real-time visualization of photo-induced dynamical processes at the nano- and molecular scale. The power and flexibility of these methods have provided unparallel insights into the fundamental optical properties of materials, leading to breakthroughs in biology, biochemistry and nanoscale physics. In this talk I will introduce key time-resolved optical techniques and demonstrate their transformative applications in tracking and controlling femtosecond processes. Highlights will include recent developments in ultrafast nanophotonics, novel platforms for light-matter manipulation and innovative design for bioinspired light-harvesting systems.
