Current research and/or projects

I am a microbiologist with research interests in molecular diagnostics, microbial ecosystems, and biofuels. I use molecular methods to identify pathogens infecting crops and other plants and develop novel methods for rapid and accurate detection.

Research and/or project statements

1. Detection and identification of phytoplasma bacteria infecting crops and other plants

2. Molecular diagnostics including the development of laboratory and field-based methods

3. Analysis of agricultural microbial ecosystems and the development of novel methods for microbial community characterization

4. Application of wood-degrading fungi to the production of biofuels
