Musahid Ahmed is a senior scientist at Lawrence Berkeley National Laboratory. Probing gas, interfacial and condensed phase chemical dynamics with  synchrotron based mass spectrometry, X-ray, infrared and terahertz spectroscopy is his passion. Recently he has discovered that ultrafast spectroscopy, X-Ray scattering and Raman spectroscopy are cool tools to allow him to chip away at deciphering dynamics in complex systems.  Recent perspectives describing various aspects of his work can be found below.
