The majority of our work has been centered on Helicobacter pylori, a bacterium that infects 50% of the global population and is linked to the development of gastric cancer. Key factors such as H. pylori adhesins and flagella-based motility are crucial for establishing infection, so my research has focused on regulating these adhesin and flagella-related genes. Our current research shifts towards identifying novel genes involved in bacterial metabolism and intracellular survival in Listeria monocytogenes. We have identified the regulon of a novel transcriptional regulator, Lmo1576, and demonstrated its role in regulating metabolism for cytosolic survival in L. monocytogenes. We have also collaborated with various groups and clinical departments to study the epidemiology of antimicrobial resistance in Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella spp., and Acinetobacter baumannii. In addition, through collaboration with Dr. Sauer (University of Wisconsin-Madison), we have identified several small-molecule inhibitors of bacterial PASTA kinases, a conserved family of proteins critical for virulence and antibiotic resistance in pathogens such as L. monocytogenes, Staphylococci, Enterococci, and Mycobacteria. Beyond developing these inhibitors as novel antibiotics, we are also investigating the downstream signaling pathways of PASTA kinases that regulate antibiotic resistance and virulence, with a focus on L. monocytogenes and methicillin-resistant Staphylococcus aureus (MRSA).
