Christopher T. Nomura's research interests center on using molecular techniques to improve the supply of precursors for biobased products. Examples include using protein and metabolic engineering techniques to generate recombinant bacterial strains to enhance production of polyhydroxyalkanoate (PHA) biodegradable polymers from renewable resources such as sugars and plant oils. Current and previous studies have used rational design of fatty acid biosynthetic enzymes based on x-ray crystal structures to alter their substrate specificity to provide monomers for PHA biosynthesis. Other research interests include genomic and microarray studies, in vitro evolution for enzyme improvement, microbial physiology, biodegradable polymer production, and polymer characterization studies.
