Research Area:

My research has focused on the selectivity and stability of heterogeneous catalysts used for biorefining applications.  This work has relied on a close interplay between computational chemistry and modeling, experimental kinetics studies, and ex situ, in situ, and operando catalyst characterization. I have studied the role of functional group on selectivity for formic acid and formate ester reforming and used helped to elucidate the active site of highly selective RhRe bimetallic catalysts.  Most recently, I have studied the use of atomic layer deposition (ALD) as a route to novel catalyst architectures that can be used to stabilize supported metal catalysts against sintering and leaching, selectively expose high coordination facets of nanoparticles, decrease coking and resinification reactions, and create bifuctional catalysts..
