Research Focus

Biological engineers routinely harness the predictability of the central dogma to modify living organisms. However, this rule cannot be easily extended to manipulations of integrated signaling networks such as central dogma, as even minor perturbations can have significant and often deleterious consequences on cellular viability. Our lab is developing and applying methodologies to study the most central biomolecular machines in living systems. We aim to understand their molecular capabilities, and to extend these capabilities to new-to-nature bioactivities. We combine principles of chemical biology, bioengineering, directed evolution, genome editing and synthetic biology to (re)engineer highly integrated cellular signaling networks towards researcher-defined function. Our research interests are broad and are focused on addressing issues of immediate global impact, namely antimicrobial development, biologics production, information maintenance and transmission, and climate change. Our work is currently supported by Scripps Research, NIH Director’s Early Independence Award, NASA, DTRA, and NIBIB.
