The interaction of light and matter is of fundamental interest to the fields of both physics and chemistry. Advances in laser technology continually push the interaction to higher energies, reaching unexplored intensities in which new science is emerging. Scott Sayres is interested in learning how quickly electrons can respond to ultrashort (femtosecond and attosecond) laser pulses. His experimental research combines three detection methods to observe how electron motion influences chemical reactions. By combining the detection of electrons, ions, and photon absorption, we gain a overall view of fundamental processes.
