Welcome to the Cook lab at UC Davis. We are a group of enthusiastic and dedicated plant and microbial biologists exploring issues related to the diversity and functional attributes of legumes and their microbial associates. Main themes in the lab include symbiotic nitrogen fixation, metagenomics of plant-associated microbes, drought tolerance, and domestication. Our work spans a range of spatial scales, from the function of natural systems distributed over thousands of square kilometers, to the sub-cellular scale, where we explore the dynamics of signal transduction systems. We employ diverse methodologies from genomics and computation, through molecular and cellular biology. Please explore this website and our allied site, the Feed the Future Innovation Lab for Climate Resilient Chickpea.
