United States Performed independent research centering on algal strain improvement and biosynthetic pathway expansion Designed and assembled genetic cassettes for transgenic strain improvement and development Generated a mutagenesis platform for generating and screening novel enzymes variants in microalgae Utilized structural information to design mutants of target enzymes in the context of a microbial biosynthetic platform for improved activity and changes in product/substrate… Show more Performed independent research centering on algal strain improvement and biosynthetic pathway expansion Designed and assembled genetic cassettes for transgenic strain improvement and development Generated a mutagenesis platform for generating and screening novel enzymes variants in microalgae Utilized structural information to design mutants of target enzymes in the context of a microbial biosynthetic platform for improved activity and changes in product/substrate specificity. Developed methodologies for 96-well block microalgae screens from scratch Developed a prototype classical mutagenesis platform for the generation of improved production strains from scratch Developed mutants with altered product and substrate specificities that enabled access to new products that were previously unattainable Performed in depth literature searches to identify unexplored enzymes for biosynthetic pathway expansion and improvement. Engineered enzymes to have augmented conversion leading to improved production strains Helped lead discussion and research projects in a small team and gave formal research updates to the entire company Interacted directly with the CEO and the Vice President of Genetic engineering to provide research updates

Sep 2011 - Jul 2016
Irvine, CA Studied protein-protein interactions in Type I iterative polyketide synthases and fatty-acid synthases. Solved the first crystal structure of a ketoreductase involved in pentangular polyphenol biosynthesis. Solved apo and hexhexanoyl-CoA-bound crystal structures of a novel long chain acyl-CoA carboxylase beta subunit. Solved the crystal structure of a NRPS/PKS hybrid condensation domain, identifying regions necessary for protein-protein recognition.
