Research interests

Microbes are continuously bombarded with a diverse set of environmental stimuli. To survive and reproduce, a cell must accurately sense and respond to these signals. Biological systems must optimally balance the ability to rapidly adapt to environmental fluctuations with energetic constraints and resource availability. I am interested in the analysis and control of biological systems spanning intracellular circuits to population dynamics. My work uses a combination of theory, computational modeling, and experimentation. I am currently a postdoc in Adam Arkin’s lab at UC Berkeley where I have been developing engineering strategies for controlling cellular resource allocation and engineering stable synthetic microbial communities.
