Areas of Interest / Expertise

  • Cell and molecular biology
  • Molecular biotechnology
  • Genomics

In my lab, we are working to identify genes that may play a role in the formation and maintenance of the cell wall in the fungus Saccharomyces cerevisiae, with an eye toward the development of more effective anti-fungal drugs. In particular, we are focused on better understanding the signal transduction pathways the cell uses to up- or down-regulate gene expression in response to changing environmental conditions. We use a wide variety of fundamental molecular and cellular tools and techniques, including: PCR, reverse-transcription (RT)-PCR, real-time (quantitative)-PCR, gene sequencing, bioinformatics, microbiological cell culture, DNA/RNA/protein analysis, gene cloning, electron & fluorescence microscopy, and microarray analysis.
