Erik Andersen Associate Professor

Research Summary: 

The Andersen laboratory uses quantitative and molecular genetics to understand the polymorphisms that underlie multigenic traits of medical, ecological, and evolutionary importance. In addition to genetics, we use new sequencing technologies, high-throughput phenotyping assays, and other genomic tools to determine the molecular mechanisms for how genetic variation causes phenotypic differences. We have broad research interests, including responses to microbial and chemical stresses, drug sensitivities, and aging-related processes.
