Areas of Interest/Research

In our laboratory we study the dynamics of biological systems. Past research has focused on the use of time-resolved optical methods to study fast (nanosecond and microsecond) processes that occur during the folding and assembly of proteins and peptides. More recently our research has focused on gene regulatory networks, especially those involved in bacterial signaling and communication. We are particularly interested in the physical aspects of bacterial quorum sensing, including the role of noise and stochasticity in quorum sensing networks, the spatial and temporal capabilities and limits of quorum sensing communication, and the ways that quorum sensing networks integrate environmental information of different types.
