Description

The Minority Serving Institutions Partnership Program (MSIPP) Internships is a new program to promote the education and development of the next generation workforce in critical science, engineering, technology, and math (STEM) related disciplines that complement current and future missions of DOE national laboratories.  The MSIPP Internship program is designed to provide an enhanced training environment for next generation scientists and engineers by exposing them to research challenges unique to our industry. 

MSIPP Interns will be given the opportunity to complete Summer Internships aligned with ongoing U.S. Department of Energy Office of Environmental Management (DOE-EM) research under the direction of a host national laboratory.  The internship will be performed at the host national laboratory, utilizing their facilities and equipment under the guidance of a research staff member.

Minority Serving Institutions are institutions of higher education enrolling populations with significant percentages of undergraduate minority students. 

Project: The Environmental Sciences Division (ESD), http://www.esd.ornl.gov, at Oak Ridge National Laboratory (ORNL), http://www.ornl.gov, has an immediate opening for two undergraduate research interns in microbiology, biochemistry, biology, biogeochemistry, or a related field. The successful candidates will conduct laboratory scale and meso-scale experiments to evaluate the performance of sorbents to limit the release of mercury from contaminated soils and sediments. Specifically this will involve data collection and analysis, interpretation, and publication of experimental results.

Abstract: Mercury (Hg) is a pervasive global pollutant which, as methylmercury (CH3Hg+), bioaccumulates in the food web and is highly toxic to humans and other organisms. Unlike inorganic forms of mercury, which originate from atmospheric deposition and point discharges, CH3Hg+ is generated in the environment predominantly by anaerobic microorganisms. Sulfate-reducing bacteria are the main producers of CH3Hg+, although iron-reducing bacteria, firmicutes and archaea can also be involved. We demonstrated that the biosynthesis of methylmercury is linked to hgcA and hgcB, two genes that are unique to methylating microbes in anaerobic environments suggesting a mercury methylation pathway common to all methylating bacteria and archaea sequenced to date. Additionally, evaluations of the influence anaerobic microbes can have on Hg release from adsorbents will also be evaluated. Research will include the use of techniques to identify proteins including SDS-PAGE, Western blots, immunostaining and mass spectrometry, and experiments that will require measuring total mercury and conducting mercury methylation/demethylation assays.

Location: This internship will be located at Oak Ridge National Lab.

Salary: Selected candidates will be compensated by either a stipend or salary, and may include one round trip domestic travel to and from the host laboratory. Stipends and salaries will be commensurate with cost of living at the location of the host laboratory. Housing information will be provided to interns prior to arrival at the host laboratory, and will vary from lab to lab.

Application Deadline:  March 27, 2017

Expected Start Date:  May 15, 2017

Qualifications

Eligible applicants must:

  • Be a citizen of the United States,

  • Be at least 18 years of age,
