AGRICULTURE IS AN EQUAL OPPORTUNITY EMPLOYER. |
ANNOUNCEMENT NO: |
RA-09-013H |
POSITION: | Research Chemist |
LOCATION: | Manhattan, Kansas |
DESCRIPTION OF DUTIES: The position is located in the Grain Quality & Structure Research Unit, at the ARS Grain Marketing & Production Research Center in Manhattan, KS. The incumbent will identify the proteins in grain sorghum and interactions of these proteins that drive the heat induced cross-linking/aggregation of sorghum proteins and how this process impacts the technological and nutritional quality of grain sorghum. The overall objectives of this project are as follows: identify the specific proteins involved in the cross-linking/aggregation of sorghum storage proteins, to determine the relationships between sorghum protein synthesis, protein-polymer cross-linking/aggregation, and protein digestibility and to identify markers for protein digestibility. Responsibilities will include extraction and analysis of sorghum proteins using reversed-phase high performance liquid chromatography, high performance capillary electrophoresis, and multi-angle laser light scattering as well as assays to determine protein digestibility and aggregation. Expected results include identification of key proteins and their interactions in heat induced cross-linking/aggregation of sorghum proteins which could then serve as markers to predict both protein cross-linking/aggregation in sorghum and protein digestibility. Incumbent will report research results at scientific meetings and author manuscripts for publication in scientific journals.
QUALIFICATION REQUIREMENTS: A recent Ph.D. in chemistry, biochemistry, plant biology or a related field is required. Knowledge and experience in protein extraction, purification and protein analysis using HPLC, HPCE, and Mass Spectrometry is desirable.
CITIZENSHIP RESTRICTIONS APPLY: Applicants must clearly indicate in their resume/CV their country of citizenship. To be employed as a Postdoctoral Research Associate with ARS, applicants must be a citizen from a country listed on the following link: http://www.afm.ars.usda.gov/hrd/jobs/VISA/countries.htm
SPECIAL CONSIDERATIONS: This position requires the selectee to undergo a pre-employment check and a full background investigation. Any offer made is considered a tentative job offer pending the outcome of the pre-employment check. Retention in the position is based upon a favorable adjudication of the background investigation.
