Horticulture Graduate Faculty

Dr. Stephanie Burnett

Associate Professor of Horticulture

Degree: Ph.D. 2004 University of Georgia
Phone: 207.581.2937
Email: sburnett@maine.edu
Location: 205 Deering Hall

Professional Interests: Floriculture, Greenhouse Management

Teaching: PSE 110 Introduction to Horticulture and Green Design, PSE 215 Vegetable and Fruit Production (Course Coordinator), PSE 219 Herbaceous Landscape Plants, PSE 415 Greenhouse Management

Research: My research focuses on improving the efficiency and sustainability of greenhouse plant production. Since competition for available water resources will increase as the population increases, one research area focuses on improving irrigation efficiency. This may be done by determining the actual plant water needs and automating irrigation based on plant need. In addition, I am interested in developing production protocols for herbaceous perennials in commercial greenhouses and nurseries.

Dr. Renae Moran

Associate Professor of PomologyMoran

Website:  Extension tree fruit site

Professional Interests: Tree fruit production and physiology


  • Environmental and genotypic variation in cold hardiness of apple trees.
  • New plum varieties for a local market.

Optimizing storage of Honeycrisp and other apple varieties to improve fruit quality and prevent storage losses.

Dr. Bryan Peterson

Assistant Professor of Environmental HorticulturePeterson

Degree: Ph. D. 2013, Iowa State University
Phone: 207.581.2918
Email: bryan.j.peterson@maine.edu
Location: 418 Deering Hall

Professional Interests: Ornamental horticulture; woody plant propagation, production, and evaluation; nursery management

Teaching: PSE 325 Turfgrass and Groundcover Management, PSE 410 Plant Propagation, PSE 430 Nursery Management

Research: The overall objective of my research is to identify, characterize, and further develop promising ornamental plants for New England landscapes, with a focus on the protection and responsible use of indigenous flora. I seek to characterize genetic diversity within high-priority taxa; to evaluate ecological and genetic security of natural genetic resources in relation to consequences of biological invasions and/or climate change; and to work toward the responsible selection, development, and release of new ornamental horticulture crops for New England’s nursery and landscape industry.

Dr. David Yarborough

Professor of Horticulture

Degree: Ph.D. 1991, University of MassachusettsYarborough
Email: davidy@maine.edu
Website: Extension blueberry site

Professional Interests: Blueberry horticulture and weed/crop ecology

Research: Research program emphasizes weed-crop ecology and weed-crop interaction using competition experiments and determining weed thresholds in wild blueberries in Maine.  Data from these experiments have been used to develop a weed management approach to be used in an integrated management program to improve production efficiency of the wild blueberries.  He now does research on developing chemical and cultural strategies for controlling weeds, and works with wild blueberry growers in Maine and Canada to educate them on best management practices that will enable them to increase their efficiency of production and their profitability, so that this industry may continue to remain competitive in the world marketplace.  He has published well over 300 research and Extension publications dealing with wild blueberries and with weeds.  He was recognized by the IR-4 program when he received the Meritorious Service Award in 2006, was elected as a fellow of the Northeastern Weed Science Society and received a Faculty Applied Research Award from the University of Maine Cooperative Extension in 2016.
