The common threads that join our research interests together are
the topics of bacterial virulence, antibiotic resistance, and
discovery of new leads for antibiotic development. Toward the
latter, we are interested in new leads that will combat infection
by Mycobacterium tuberculosis. We are also interested in
compounds to address a variety of fungal and oomycete agricultural
pathogens. We focus on three main systems. Read more about each
one by following the corresponding links.
1) the multifunctional heme enzyme known as KatG,
2) two enzymes essential for aromatic amino acid biosynthesis, shikimate dehydrogenase
and shikimate kinase, and
3) antimicrobial compounds generated by Bacillus and Paenibacillus
biosynthetic gene clusters
