Welcome to the Blekhman Lab

Evolutionary, Population, and Medical Genomics

Located at The University of Minnesota, Twin Cities, we are part of the Departments of Genetics, Cell Biology, and Development, and Ecology, Evolution, and Behavior

Our lab

The Blekhman lab's broad focus is on Population, Evolutionary, and Medical Genomics in humans and other primates. A major focus of our research is on the trillions of bacteria that colonize each of us. The lab generates genomic data, and employs computational, statistical, network-theory, data mining, and population genetic approaches, with the goal of understanding how we interact with our microbial communities, how host-bacteria interactions affect complex traits and disease, and how the symbiosis between us and our microbiome evolved throughout human history.

 We are looking for highly motivated researchers to join our group! Read More...
