About this position
This postdoctoral fellowship is hosted by the U.S. Department of Agriculture’s Agricultural Research Service in Wyndmoor, Pennsylvania, within the Sustainable Biofuels and Co-Products Research Unit. The project focuses on turning herbaceous feedstocks into higher-value bio-based materials by extracting, characterizing, and using lignin from lignocellulosic biomass such as switchgrass and hemp.
The fellow will help carry out lignin fractionation experiments, recover dissolved lignin after chemical pretreatment, and support analytical characterization of the recovered material. The research then uses that lignin in the preparation of bio-based materials, linking biomass conversion with materials development.
The training environment emphasizes hands-on laboratory work and research communication. The fellow will gain experience with analytical techniques including HPLC, TGA, NMR, and FTIR, and will also contribute to data recording, analysis, scientific reporting, and presentation of progress in group meetings.
The work is mentored by Ryan Stoklosa in a USDA-ARS research unit that advances chemical, catalytic, thermal, enzymatic, and fermentative technologies for converting low-value agricultural materials into renewable chemicals and materials.
