The relationship of transcriptional activity with the intra-nuclear positioning of genes has been well documented, particularly relative to the periphery of the nucleus.  Localization at the nuclear periphery is traditionally a hallmark of gene silencing.  However, our lab and others using the yeast ''Saccharomyces cerevisiae'' as a model, have shown that active genes are also present at the nuclear periphery and that the nuclear pore complex is an important mediator of genome organizationIn fact, certain genes are recruited to the NPC upon transcriptional induction.

My research interests involve the mechanism(s) of genome interaction with the nuclear pore complex and nuclear periphery, especially in regards to gene activation and the dynamics of the process.  Chromosomes are not static structures, and their constrained diffusive movement most certainly plays a role in many nuclear processesWe have employed the lac operator/GFP-lac repressor system to visualize the real-time motion of the ''GAL'' locus in live-cells.  In this way we can observe how transcriptional induction can affect ''GAL'' locus motion in a population of yeast.  Furthermore, we can then perturb the system via mutants, etc. to begin looking at what factors play a role in the phenomenon of gene recruitment to the nuclear periphery.

Research Interests

We (with students Jake and Bill and the gracious help of the rest of the synthetic biology team) are pursuing the design and construction of a cell-based, multi-plex sensor-memory device. Such a device will be able to report whether specific events occur in a cell or whether certain compounds are present in the cell's environment. Furthermore, such a system is also designed to report on how much of a thing the system is sensing, and storing such information in itself as well as its descendants. A key feature of such a system will also be its portability to various environmental stimuli/cellular events.
