Assistant Professor


Email: jmelgar@clemson.edu

Department:
School of Agricultural, Forest and Environmental Sciences


Education:
Ph.D. Crop Production and Protection, 2006, University of Cordoba, Spain
B.S. Agricultural Engineering, 2000, University of Cordoba, Spain

Responsibilities:
Research and extension in the areas of pomology

Research interest:
My research goals are to solve problems in fruit tree growing that can have significant economic, social and environmental impacts. I am also committed to inspire and encourage students to go beyond where they are by stimulating their interest and critical thinking.
