Use of a variety of molecular techniques (SNPs, AFLPs, allozymes, microsatellites, Introns, etc.) to study genomic variation in natural and aquacultural populations. Examine questions related to genomic structure, population analysis, mixed stock analysis, genomic manipulation, effects of non-indigenous species/populations, and isolate identification in fish, fungi, birds, mammals, plants, and invertebrates. Exploring the use of SNP and microsatellite data to address questions in conservation biology regarding the "genetic health" and "genetic integrity" of natural populations. Linkage of molecular markers to single quantitative trait loci (QTLs).
