In this project, I applied NASP for single nucleotide polymorphism (SNP) identification and characterization, and used FigTree and PHYLOBar for phylogenetic analysis and visualization.The NASP method differs from other published SNP pipelines in terms of supported short - read aligners and SNP callers, the ability to call both monomorphic and polymorphic sites, and the ability to integrate the results from multiple SNP callers and identify the consensus set of SNPs that define the population structure.

He has particular interests in (1) the use of ancient DNA methods to document changes in genetic variation through time and phylogenetic relationships of extinct or endangered organisms (especially of the recently extinct Hawaiian avifauna); (2) the use of highly variable genetic markers to measure genetic structure and relatedness, and to ascertain mating systems, in natural populations, and (3) the use of genetics to study the evolutionary interactions between hosts, vectors and infectious disease organisms (e.g., major projects on introduced avian malaria in native Hawaiian birds and invasive chytrid fungus in amphibians).
