Areas of Expertise

I apply my background in structural biology and plant/algal cell biology to address questions about the cellular mechanisms involved in cell wall assembly, the biochemical and biophysical principles that determine the architecture of cell wall biopolymers, and revealing the mechanisms of enzymes and microbes that deconstruct cell walls.

NREL's Biomass Surface Characterization Laboratory is a collection of imaging technologies including laser scanning confocal microscopy, confocal Raman microscopy, environmental scanning electron microscopy, atomic force microscopy, and transmission electron microscopy, which we use to better understand structural changes during biomass conversion.

We are expert at biomass sample preparation including cryopreservation, ultra-microtomy, immuno-EM, and using electron tomography as a technique to study the complex 3-D architecture of the plant and algal cell walls at the macromolecular scale.
