Welcome to the Gaynor Laboratory! We are a team of people who seek to understand how complex molecules and materials can use light to move charge and energy in photoexcited states of condensed phases. It is our hope that a deeper understanding of interesting photochemical dynamics will enable future breakthroughs in more efficient technologies that can combat global issues that we face as a society. To achieve this, we push the frontiers of nonlinear multidimensional spectroscopy to measure dynamic couplings and correlations among electrons, nuclei, and their environment that govern fundamental processes like quantum coherence and the motion of charge and energy. Using pulses of light that range in duration from 100’s of “atto”-seconds (1 as = 10-18 seconds) to 10s of femtoseconds (1 fs = 10-15 seconds) and that spectrally span from 4 nm to 15000 nm, we track the motion of charge and energy – from quantum coherences to transfer and solvation – with exquisite sensitivity and selectivity.
