Research in my lab involves applying the methods and skills of metabolic systems biology to optimize growth rate and biofuel production rates of diverse microorganisms. We supplement experiments with modeling approaches in order to streamline discovery and optimization. This includes application of flux balance analysis (FBA) and metabolic flux analysis (MFA) to identify the intracellular distribution of metabolic fluxes and identify the targets for further manipulation. The predictions of metabolic modeling are verified experimentally. This approach is being investigated in various microorganisms, including, but not limited to, native isolates of cyanobacteria. Additionally, traditional metabolic engineering (knock-out and overexpression of genes) as well as synthetic biology approaches (introduction of optimized heterologous pathways) are being employed in cyanobacteria to make diverse products including biofuels.
We are also actively investigating improved productivity through adaptation and process optimization. This includes systems biology investigation to identify the changes associated with improved strain performance.
