Microbial ecology of the atmosphere and plant-microbe interactions:
Bioprospecting efforts in the lower atmosphere have yielded novel Actinomycetales that produce antimicrobial compounds.

We work at both organismal and landscape scales to understand the composition and ecological roles of microbes in the lower atmosphere as well as those associated with plants.  

Current investigations are demonstrating that plant growth promoting microbes may be abundant in the atmosphere above certain terrestrial habitats.

Ice-nucleating capabilities of some microbes and plant spores may control their dispersal to new habitats and their ability to influence cloud formation and weather patterns.
