Dr. Molly Jahn is professor of genetics at University of Wisconsin - Madison. Her work in traditional plant breeding has contributed to crop varieties that are grown on six continents, and she has worked extensively in developing countries to link crop breeding with improved human nutrition and welfare. She's leading a global alliance of research groups focused on "making the consequences of our failures to change visible to us." Systemic risks that originate from shortcomings in the food system are Molly's forte. "Can we, together, find ways of existing that steward our resources adequately?" she wonders (and it's clear that "no" is not an acceptable answer).
