Profile Summary

My background is in biological and solid state physics with an emphasis in the characterization of biomass degrading proteins and pretreatment of biomass. Throughout my career, I have developed and implemented novel characterization and data analysis techniques to obtain a better fundamental understanding on how fungal and bacterial cellulase systems break down different biomass feedstocks into fermentable sugars for use in ethanol and advanced biofuels. I am currently at the National Renewable Energy Laboratory as a Scientist III working in the areas of fungal cellulase's, bacterial cellulase's and cellulose nanocrystals for uses in advanced biomaterials. I am also currently perusing an MBA and a Business Analytics masters degree with an emphasis in predictive analytics and business forecasting. I have developed a passion for data analytics and big data and have begun incorporating these techniques within my scientific career. Specialties: Business forecasting, Predictive Analytics, Data analytics, Statistics, JMP, R, Mathematica, Quarts Crystal Microbalance with Dissipation, Enzyme Kinetics, Pretreatment, Spectroscopy,
