Doctoral Graduate Student Position:

Molecular Systematics and Taxonomy of Entamoeba.


Institute: University of Arkansas, Department of Biological Sciences, Fayetteville AR USA.


PhD. position is available starting as soon as October 1 2009 to work on molecular and morphological characterization of Entamoeba that infect invertebrate hosts (with possible expansion to other little-studied host systems).


The project will focus on the molecular phylogeny (1 SSU) of invertebrate infecting Entamoeba accompanied by detailed morphological and life-history descriptions for a-taxonomy.  Culturing of organisms from infected hosts will be attempted/optimized. Gene sequences will be obtained either from cultured organisms or from 'environmental' PCR from host gut-content DNA.  Evolutionary relationships and history will be inferred from molecular phylogenies. Acquisition of multiple genes from each new isolate will be encouraged with the goal of generated a robust, rooted phylogeny.

Taxonomic revision and criteria for species designation and taxonomy of these parasites will be critically evaluated.


Starting date: October 2009 January 2010. Search will continue until a suitable candidate is identified.
