Bacterial pathogenesis and host pathogen interactions. Currently investigating the interactions of Francisella tularensis with amoebae and their role in the environmental persistence of F. tularensis and their impact on pathogenesis. Also studying the response of mammalian host cells to F. tularensis infection.
Honors and Awards
Awarded an LDRD-LW grant in 2008 from LLNL/ DOE to investigate the role of dendritic cells in the pathogenesis of tularemia.
