Synthesis of platform chemicals, specialty chemicals, and biofuels from lignocellulosic biomass using novel catalytic and separation processes.
The overall goal is to increase the sustainability of biofuels and chemicals produced from lignocellulosic biomass by improving processing methods, increasing reaction rates, and increasing the yields of biomass carbon that is converted into biofuels and chemicals. This includes developing novel, high yield biomass deconstruction methods, improved biomass conversion processes to increase catalyst stability, and separation methods using zeolite membranes.
Current Lab Openings
**Potential graduate student researchers must first fill out the pre-application form (no fee required)** If you are interested in joining my laboratory, please fill out the pre-application form and then contact me at the email above. I will be happy to discuss the opportunities below with you if you meet the proper qualifications. Applicants must have exceptional qualifications and should consider applying for an external fellowship.
As of 08/26/13, there are 2 graduate student openings for begining in the Spring or Fall of 2014. The projects that have openings include a zeolite project (separations and material science based) and a renewable chemcial project (separations and catalysis based). If you are interested in either project, please follow the instructions above.
If you are interested in joining my laboratory, please stop by my office or contact me at the email above. I will be happy to discuss the opportunities below with you if you meet the proper qualifications. Applicants must have exceptional qualifications and should consider applying for an external fellowship, such as the USP.
