Research Interests

Genomics and Gene Expression

Research Summary

Cells respond to environmental or developmental signals by reprogramming the expression of specific genes throughout their genome. We wish to understand the mechanisms by which this occurs. To do so, we have used genomics-based approaches to decipher how gene expression is regulated in the model eukaryotes Saccharomyces cerevisiae and Arabidopsis thaliana, with the hope that the lessons we learn in yeast and plants will be applicable in mammalian systems. Ongoing projects include the (1) use of DNA microarrays to profile genome-wide mRNA levels in various transcription factor and histone mutant strains; (2) analysis of global protein-DNA interactions using DNA microarrays; and (3) the development of bioinformatics tools to analyze promoter sequences and DNA microarray data. These projects involve the development and use of cutting-edge biotechnology to investigate how genome expression is regulated in eukaryotic cells.
