Bio

kayakingI grew up in Georgia but have lived in the mid-Atlantic area for almost two decades. My research in microbial ecology and the structure and function of bacterial communities has taken me from the beaver ponds in northern Canada, to the coastal and inland waters of Georgia and the mid-Atlantic incropped-field.jpgcluding the Patuxent and Anacostia Rivers.  I was a Knauss Sea Grant Policy Fellow and did my postdoctoral work at the Academy of Natural Sciences in Philadelphia. My research has been published in several journals including Nature, BioScience, the Journal of the Northern American halfBenthological Society, and the Journal of Environmental Pollution Research.  I am very interested in issues  related to microbial ecology, sustainability, and public health.  I love photography, gardening, outdoor activities, and hanging out with my family.
