Ph.D. Graduate Assistantship, Environmental Genomics

University of Arkansas

An NSF-funded graduate research assistantship is available to support
a Ph.D. candidate interested in functional genomics of adaptation and
evolution.  The project involves laboratory and field experiments
designed to discover patterns of gene expression in populations of
cactophilic Drosophila mojavensis exposed to different host plants in
stressful and non-stressful thermal regimes. Our general goals are to
uncover whole-genome patterns of gene expression in populations
exposed to natural abiotic and biotic stress.  Ultimately, we wish to
pinpoint clusters of functionally interacting genes expressed
throughout the life cycle in different environments, and predict
limits of phenotypic plasticity and adaptation, particularly in
response to stressful environments and long-term global climate change.

Laboratory experiments involve DNA microarrays to study gene
expression changes due to different host cacti and temperature
stresses, as well as differences in epicuticular hydrocarbons. Field-
related work will include multiple field trips to Mexico to monitor
wild flies, assess demography of wild populations, and analyze
cuticular hydrocarbon and RNA profiles.  Other related research
projects are also possible. This position is part of a collaborative
project involving the Univ. of Arkansas, Fayetteville, and the Univ.
of Nevada, Las Vegas.

Applicants must gain admission to the Ph.D. program in the Department
of Biological Sciences at the University of Arkansas.  Application
information is available at http://biology.uark.edu/1251.htm.  Full
stipend, tuition, and benefits are included.  Supplemental funding is
available on a competitive basis for applicants qualifying for
Doctoral Fellowships at the Univ. of Arkansas (http://
biology.uark.edu/1255.htm).
