Julie Dawson
Urban and peri-urban farm enterprises are very diverse in their marketing and management strategies, and I am interested in providing research support for small-scale farm and food enterprises serving regional markets, and community gardens focused on food security. I welcome input on research priorities and ideas for projects. If you are interested in participating in research or education projects, please contact me!

Amaya Atucha
Amaya Atucha is an assistant professor in the department of Horticulture and the Fruit Crop Extension Specialist at the University of Wisconsin-Madison. She is also the Gottschalk Chair for cranberry research. Her instruction responsibilities include teaching Hort 345 Fruit Crop Production.

Her research program focuses on fruit crop physiology and production of deciduous fruit crops (cranberry, apple, and grapes in particular). Her current research areas include cold hardiness of fruit crops, improving fruit quality of cold hardy wine grapes through cultural practices, and differences in root growth rates of rootstocks as affected by soil borne pathogens.

The goal of her extension program is to deliver up to date, research-based information to fruit growers that will lead to improve production practices of fruit crops in Wisconsin.

She earned her B.S. in horticulture from the Pontificia Universidad Católica de Valparaíso (Chile) and her Ph.D. in horticulture from Cornell University. Prior to joining UW-Madison she was an assistant professor at Colorado State University in the department of Horticulture.

Sara Patterson
Much of the focus of the Patterson laboratory during the last decade has been the characterization of the abscission zone in numerous plant species and the identification and characterization of genes that regulate cell separation, using floral organ abscission in Arabidopsis as a model system. The anatomically distinct band of small densely cytoplasmic cells located at the region of cell separation can be referred toas the abscission zone (AZ) and these cells have distinct morphological characteristics. In some plants the fruit abscission zone is composed of lignified cells in the valve and vasculature that surround a non-lignified separation layer. Several studies have shown that the structure of the abscission zone and the process of shattering are similar between Arabidopsis and many plant species. The lab uses a variety of techniques including scanning electron microscopy (SEM), breakstrength, light microscopy, in situ hybridization, and expression of molecular markers in the characterization of novel mutants that the laboratory has isolated.

Irwin Goldman
Our lab focuses on breeding and genetics of cross-pollinated vegetable crops; primarily carrot, onion, and table beet. The year 2016 marks our 67th year working with these crops, and over these years we have released numerous inbred lines, open pollinated populations, and germplasm for use by breeders throughout the world. Our lab also studies traits of importance in these crops and seeks to find new methods of breeding and genetic improvement. A theme running through our work is the examination of traits of consumer interest, such as health value, color, flavor, shape, and other quality attributes. Our lab is located in the Department of Horticulture at the University of Wisconsin-Madison, 1575 Linden Drive, Madison, WI 53706.
