Welcome to the Fournier Lab!
We design and implement new techniques which combine the sensitivity and selectivity of mass spectrometry with the time resolution of ultrafast spectroscopies to capture and interrogate fast chemical reactions with molecular-level detail, offering new insight into reaction mechanisms that are too challenging to study with standard methods.
Recent Lab News
