Christine Thacker's Research

  Christine Thacker studies the evolution, systematics, biogeography, morphometrics, and genetics of acanthomorph fishes, specializing in gobies and cardinalfishes.  Her work has explored the evolution and relationships of gobies from intraspecific to interfamilial scales, including a phylogenetic classification of families within the order Gobiiformes.  As of June 2018, she is retired from the NHM and holds the position of Emeritus Curator. Selected publications may be downloaded below:
