From 1984 to 1986 he was a
postdoctoral fellow at
University of Colorado, in the lab of
W. Carl Lineberger at
JILA. His research has involved the probing
transition states using negative ion
photoelectron spectroscopy, investigation of the properties and dynamics of
hydrated electrons using
time-resolved photoelectron spectroscopy on
water clusters. Neumark and fellow Berkeley professor
Stephen Leone have collaborated on research probing
quantum dynamics using
attosecond spectroscopy. ==Awards and honours==
