Andrew Kinziger, Ph.D.

Current Research Interests

  • Application of high-throughput sequencing to conservation and management of fishes
  • Use of environmental DNA in water samples to monitor distribution and abundance of fishes
  • Use of genetic data to make inference into the ecology and evolution of fishes, including divergence in adaptive and neutral traits, genetic stock identification, invasion genetics, and riverscape genetic structure
  • Research spans a broad taxonomic range, including salmonids, cyprinids, tidewater goby, catostomids, Cottus, and other freshwater and marine fishes
