Other Teaching and Advising

I advise several graduate students and postdoctoral researchers in the Department.  I have also participated in developing a dual degree program between Virginia Tech and the National Engineering School of Sfax (Tunisia).  This program was funded by the U.S. State Department.  Currently, I am the faculty advisor for the American Society of Agricultural and Biological Engineers (ASABE) student chapter at Virginia Tech, and I am head of the Potential Employers Committee in the Department.

Program Focus

My research program is focused on deriving valuable chemical intermediates, specialty products, and fuels from biological sources.  To do this, we focus in the areas of metabolic engineering, systems biology, and synthetic biology.  We are primarily concerned with enzymatic conversion of biological feedstocks (including photosynthesis) and are developing new technologies in the following areas: (i) metabolic engineering in silico using genome-scale models, (ii) RNA regulation, (iii) genomic library enrichment, (iv) synthetic metabolic pathways, (v) synthetic regulatory circuits, and (vi) cellular phenotype identification and molecular imaging using Raman spectroscopy.

Current Projects

  • Metabolic engineering of Clostridium cellulolyticum using a genome-scale model and combinatorial approaches
  • Photanol: Biosynthesis of alcohol biofuels from CO2
  • Model-guided metabolic engineering of Arabidopsis for increased cellulose production
  • Predicting high-oil phenotypes for seed rational metabolic engineering using genome-scale modeling
  • Enzymatic synthesis of high-value building blocks for commodity and specialty chemicals: A bottom up approach
  • Generating environmentally-friendly novel biofuel molecules with synthetic biology
