**Molly Jahn** is an American plant geneticist and breeder and Professor of Agronomy at University of Wisconsin-Madison, USA. She was Under Secretary of Research, Education and Economics in the [U.S. Department of Agriculture](/source/United_States_Department_of_Agriculture) (2009 - 2010).

## Career

Jahn (originally Kyle) graduated with BA in biology (with Distinction) from [Swarthmore College](/source/Swarthmore_College) in 1980. She subsequently completed a master's degree at [MIT](/source/MIT) in 1983 and obtained her doctorate in [plant breeding](/source/Plant_breeding) and plant pathology from [Cornell University](/source/Cornell_University) in 1988. She was appointed assistant, associate and finally full professor of plant breeding and plant biology at Cornell University from 1991 to 2006.[1] She moved to University of Wisconsin-Madison where she was dean of the College of Agricultural and Life Sciences, and director of the Wisconsin Experiment Station from 2006 - 2011 and continues as professor of agronomy.[1]

She also hold appointments outside University of Wisconsin-Madison. During 2009–10, she was Deputy and Acting Under Secretary of Research, Education, and Economics at the U.S. Department of Agriculture.[2] She was seconded to NASA in 2019-20 and continued as 25%-time Director of Strategic Outreach, NASA Harvest Consortium into 2022.[3][4]

## Scientific research

Her research interests include plant genetics and genomics especially the resistance of plants to viruses. She has concentrated on the [Solanaceae](/source/Solanaceae) specifically potatoes, tomatoes and pungency in *Capsicum*, but has also worked with melons, squashes and pumpkins. She has been involved with and led plant breeding programmes that have resulted in new cultivars of squash (including All American Selections Winner *[Bush Delicata](/source/Delicata_squash)* in 2002;*[Honeynut](/source/Honeynut_squash#History)* in 2014; All American Selections Winners *Honeybaby F1* and *Sugaretti* in 2017), pepper, melon and cucumber (*Salt and Pepper* in 2011) varieties as well as having received awards for potato breeding.[5]

As well as plant breeding her research has involved fundamental aspects of plant physiology. As her career has developed she has become more involved in public policy areas of plant science, particularly related to world food security.[6][7]

## Distinctions

Jahn has served on advisory boards including the US National Academies of Science Board on Agriculture and Natural Resources, the [Santa Fe Institute](/source/Santa_Fe_Institute) Science Board and was the USA representative on the [CGIAR](/source/CGIAR)’s Commission for [Sustainable Agriculture](/source/Sustainable_agriculture) and Climate Change.[8]

In 2012 she was awarded a USDA Secretary's Honor Award for an electronic suggestions box so USDA employees could make anonymous suggestions to improve the agency.[9]

Jahn has been awarded Honorary D.Sc. degrees from [Anglia Ruskin University](/source/Anglia_Ruskin_University), UK in 2014[6] and Swarthmore College in 2015.[10] She was commencement speaker at the [University of Sydney](/source/University_of_Sydney) in 2016. She is also a Fellow of the [AAAS](/source/American_Academy_of_Arts_and_Sciences) and the Wisconsin Academy of Arts, Sciences and Letters.
