Murray Mass Spectrometry Group – Research group of Kermit Murray at Louisiana State University where we use lasers for sampling and imaging and study the chemistry and physics of laser ablation.

Murray Group research is aimed at instrument development for mass spectrometry using laser desorption and ablation with applications to biological imaging and separations coupled to mass spectrometry for complex mixture analysis. Our research interests range from exploring the fundamental processes of laser desorption to biological applications.
