Harvard University

Program in Biological and Biomedical Sciences
Ph.D., Microbiology and Molecular Genetics (May 2012)
Dissertation: Bistability in Pseudomonas aeruginosa

University of Iowa

B.S., Microbiology with Honors and Computer Science (May 2006)

Research Experience

The University of Texas at Austin

Postdoctoral Fellow (2012-present)
Advisor: Marvin Whiteley

  • Project: Fitness determinants of P. aeruginosa for growth in disease conditions
    • Investigating the genetic requirements for P. aeruginosa growth in CF lung secretions
    • Map the conditionally essential genome for burn wound infection and systemic invasion
  • Project: Mapping all synthetic genetic interactions in a bacterium using second-generation sequencing

Harvard University

Ph.D. Student (2006-2012)
Advisor: Simon L. Dove

  • Project: An epigenetic switch that controls virulence gene expression in P. aeruginosa
    • Characterized the bistable BexR regulon in P. aeruginosa
    • Determined a requirement for positive feedback in bistable expression of bexR and the bexR regulon
  • Project: Control of cupA fimbrial gene expression in P. aeruginosa by the LysR-type transcription regulator MexT
    • Discovered a role for PrrA, an unannotated sRNA encoded downstream of the MexT-regulated mexEFoprN antibiotic efflux pump genes, in bistable cupA gene expression
    • Generated evidence suggesting that PrrA negatively regulates the H-NS-like protein MvaU
  • Project: Inducible protein degradation in P. aeruginosa
    • Adapted a targeted protein depletion system for use in P. aeruginosa and demonstrated its utility in determining the co-essentiality of the H-NS-like proteins MvaT and MvaU

University of Iowa

Research Assistant (2002-2006)
Advisor: Michael A. Apicella

  • Project: Biochemistry of sialic acid transport in Haemophilus influenzae
    • Purified the sialic acid transport protein SiaP and characterized its sugar-binding biochemistry
