Todd Vinzant manages the Biomass Surface Characterization Laboratory. The focus of the facility is in the structural characterization of biomass as a function of chemical and enzymatic conversion, which includes the structural characterization of the microorganisms that generate the scarifying enzymes and those responsible for the fermentation of the free sugars. The facility is designed for a correlative approach to imaging to span the resolution from molecular interaction and observation to anatomical characterization.

He also leads a project to investigate lignin migration phenomena. This work addresses the structural changes in the lignin structure as a function of pretreatment temperature and chemistries. The team is developing a model to describe the sequence of structure changes within biomass that accounts for the movement of carbohydrates and lignin. The objective of this work is to determine the structural mechanism(s) of lignin's adverse role in biomass conversion.
