We seek to understand how biological systems exploit quantum mechanical phenomena. For example, photosynthetic antenna complexes use coherent energy transfer to move energy with extreme efficiency despite a dynamic, disordered environment. We use femtosecond laser systems to probe energy transfer on ultrafast timescales in an attempt to unravel the design principles that nature uses.
