Research Interest:
Computational approaches to solving problems in bacterial pathogenesis is the overarching theme of my research. Novel methods for the discovery of previously unknown virulence genes interests me the most. I have pursued several projects to find a methodology for characterizing effectors and their chaperones in order to filter genomic data in search of candidates for experimental analysis. These methods include the use of protein properties such as hydrophobicity and amphipathicity, codon or peptide usage statistics and common regulatory promoter sites.

Another area of interest is visualization methods for integrating heterogeneous data. In particular, I am looking for new ways to display expression data from microarrays and proteomics along with genome sequence and annotation. The purpose of this project is to aid investigators in comprehending experimental results that encompass large data sets that spans many protein metabolic pathways and functions.
