Two Postodoctoral Research Associate Positions

The Environmental Sciences Division of Oak Ridge National Laboratory
(ORNL) invites qualified persons to apply for two Post-Doctoral Research
Associate position at the Laboratory in:

Physiological Ecology/Plant Physiology
Plant Molecular Genetics

The successful candidates will join a multi-disciplinary team of
investigators addressing how a single-gene change in an important
biological process (i.e., nitrate assimilation) translates across
multiple levels of biological organization to produce detectable and
predictable responses at the ecosystem level. Wild type and transformed
Arabidopsis, and mixtures of the two, will be grown at ambient and
elevated CO2 in order to identify physiological linkages between the
carbon and nitrogen cycles. The work will contribute to a Department of
Energy, Office of Science, Program for Ecosystem Research funded project
investigating how environmental change influences the structure and
function of terrestrial ecosystems.

The Physiological Ecology/Plant Physiology associate will assist in the
design and operation of hydroponic and soil-based mesocosms, the latter
to include capabilities for system-level measurements of carbon and
water exchange. This candidate will also be expected to provide
expertise in one or more of the following areas; leaf and whole-plant
physiology, nitrogen acquisition, and modeling. The principal
qualification is a Ph.D. degree in plant physiology, ecology, or related
environmental science field.

The Plant Molecular Genetics associate will produce transgenic plants
using existing RNAi vectors and floral dip transformation, and perform
extensive characterization of transcriptional responses of the
transgenics to the environmental treatments.  Candidates should have a
Ph.D. degree in molecular biology, genetics, or a related field.
Experience with plant molecular genetics, tissue culture, and microarray
analysis is preferred.

Excellent oral and written communication skills and willingness to work
in a multi-disciplinary team are required. These are three-year
positions with opportunity for advancement.  Preferred starting date is
February 1, 2005, and applications will be accepted until the positions
are filled.

Qualified applicants are invited to send a current resume and a list of
3 or more references to the attention of Dr. Stephen P. DiFazio,
Environmental Sciences Division, Oak Ridge National Laboratory, P.O. Box
2008, Oak Ridge, TN 37831-66422, or e-mail to difazios at
