Education

  • Ph.D. in Microbiology and Immunology, University of Texas Health Science Center at San Antonio, 1992
  • B.A. in Biology, University of Dallas, 1986

Research interests

  • Examination of oral bacteria using genetic, genomic, post-genomic and molecular biological approaches.  I am particularly interested in examining Streptococcus sanguinis, both in its ability to serve as a beneficial member of the normal oral flora and in its role in causing infective endocarditis, a serious cardiac infection.
