Biography and Research Information

OverviewAI-generated summary

Andrew D. Sweet's research investigates the evolutionary history and diversification of parasites, particularly lice, in relation to their hosts. His work employs molecular phylogenetics and genomics to reconstruct evolutionary relationships and understand the factors driving host specificity and adaptation. Sweet has explored the impact of host dispersal on parasite evolution, using examples such as pigeons and doves to illustrate how host movement can create new ecological opportunities for parasites.

His research also delves into the intricacies of mitochondrial genome evolution, specifically the phenomenon of fragmentation and its correlation with increased rates of molecular evolution. This includes the recovery and analysis of ancient DNA from environmental samples like packrat middens. Sweet is the Principal Investigator on a National Science Foundation (NSF) grant totaling $496,624, focused on unraveling the phylogenetic and evolutionary patterns of fragmented mitochondrial genomes in parasitic lice. His work also extends to studying inbreeding patterns and population structure in louse populations, including those of endangered species.

With a publication record of 95 papers and 1,332 citations, Sweet is recognized as a highly cited researcher. He collaborates with colleagues at Arkansas State University, including Than J. Boves, Asela Wijeratne, Paige Brewer, and Alexander J. Worm, with whom he has co-authored multiple publications. He also maintains an active lab website to showcase his group's research.
