Research Interests

Tree Fruit Horticulture & Physiology

A primary focus is on cultural (innovative production systems) and physiological (reproductive and environmental stress) factors important to efficient production of high-value tree fruits. My laboratory group takes a diverse and integrative research approach through studies of meristem determination and growth regulation, carbon and nitrogen assimilation and partitioning, rootstock evaluation and characterization, and environmental limitations to refine orchard systems and management, primarily in stone fruits.

Orchard Microclimate Modification Technologies

A primary focus is on understanding and optimizing the utilization of orchard microclimate-modifying technologies, such as high tunnels and retractable covering systems, to enhance production quality and consistency of tree fruits including sweet cherries, apricots, nectarines, and plums.

Sweet Cherry Genetic Improvement

A primary focus is on identification, evaluation, and development of important traits found within sweet cherry scion and rootstock germplasm to enhance fruit quality and reduce production inputs, such as fungicides.

Bacterial Canker Research

In collaboration with plant pathologists, my laboratory group also focuses on developing integrative strategies for reducing Pseudomonas syringae infections in sweet cherry production.
