United States-New Deputy Sectretary of Agriculture-Kathleen Merrigan.

President Barack Obama on Tuesday announced his intention to nominate Kathleen Merrigan to be deputy secretary of agriculture.

"She will bring to USDA extensive expertise in agricultural marketing and nutrition and in legislative affairs and will provide excellent, experienced leadership as we move President Obama’s agricultural and nutritional agenda forward," Agriculture Secretary Tom Vilsack said in a news release.

Merrigan is currently an assistant professor and director of the Agriculture, Food and Environment M.S. and Ph.D. Program at the Friedman School of Nutrition Science and Policy at Tufts University in Boston.

In 1999, she was appointed administrator of USDA’s Agricultural Marketing Service by then-President Clinton. Prior to that, Merrigan was a senior analyst at the Henry A. Wallace Institute for Alternative Agriculture and an expert consultant at the Food and Agriculture Organization of the United Nations in Rome.

From 1987 to 1992 she was a staff member on the U.S. Senate Committee on Agriculture, Nutrition and Forestry, where she helped develop the Organic Foods Production Act of 1990, which mandated national organic standards and a program of federal accreditation.
