A research opportunity is currently available with the U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), located in Athens, Georgia.

The Agricultural Research Service (ARS) is the U.S. Department of Agriculture's chief scientific in-house research agency with a mission to find solutions to agricultural problems that affect Americans every day from field to table. ARS will deliver cutting-edge, scientific tools and innovative solutions for American farmers, producers, industry, and communities to support the nourishment and well-being of all people; sustain our nation's agroecosystems and natural resources;

and ensure the economic competitiveness and excellence of our agriculture. The vision of the agency is to provide global leadership in agricultural discoveries through scientific excellence.

The Exotic and Emerging Avian Viral Diseases unit is part of the USDA-ARS, US National Poultry Research Center. The vaccinology, pathobiology, transmission dynamics and diagnostics for highly pathogenic avian influenza (HPAI) virus in poultry and livestock are a primary research focus of the unit. You will be part of the team which is evaluating and developing vaccines against HPAI. Currently, the US is experiencing one of the largest HPAI outbreaks and there has been serious consideration for the use of vaccines as a component of integrated control programs.

You will evaluate the efficacy of commercial and experimental vaccines. The project involves studying the potential of field viruses to infect and spread in vaccinated animal and evaluating DIVA (Differentiation of Infected from Vaccinated Animals) strategies to show that vaccinated animals have not been infected with field virus. The project also involves studying the immune correlates of protection and antigenic relationships between vaccine and field viruses.

• Learn about highly pathogenic avian influenza (HPAI) in poultry and livestock, including its transmission, disease impacts, and role in current outbreak-response efforts.
• Gain experience supporting the evaluation and development of commercial and experimental HPAI vaccines.
• Learn how vaccine efficacy is assessed, including measuring protection against infection, disease, and virus transmission in vaccinated animals.
• Develop familiarity with studies that evaluate whether circulating field viruses can infect or spread among vaccinated poultry or livestock.
• Gain knowledge of DIVA strategies-Differentiating Infected from Vaccinated Animals—and their importance for vaccination-based disease-control programs.
• Learn how diagnostic approaches can distinguish vaccine-induced immune responses from evidence of field-virus infection.
• Develop an understanding of immune correlates of protection, including how immune responses are associated with successful vaccination outcomes.
• Gain experience examining antigenic relationships between vaccine strains and field strains to inform vaccine selection and effectiveness.
• Build collaborative research skills within a multidisciplinary team focused on avian-influenza vaccinology, pathobiology, diagnostics, and transmission dynamics.

The mentor for this opportunity is Chang Lee (chang.lee). If you have questions about the nature of the research, please contact the mentor(s).

2026.

The appointment will initially be for one year, but may be renewed upon recommendation of ARS and is contingent on the availability of funds.

The appointment is full time.

This opportunity is available to U.S. citizens only.

This program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and ARS. Participants do not become employees of USDA, ARS, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program.

Health insurance can be obtained through ORISE.
