Dr. Lu is conducting and leading research in sensors and sensing technologies for property characterization and quality evaluation of fruits and vegetables. He is Lead Scientist for the federally appropriated in-house research project “Technologies for Quality Measurement and Grading of Fruits and Vegetables” with the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS)- the principal federal government research agency in agriculture, food and natural resources. His research applies state-of-the-art technologies in imaging, spectroscopy, and computer as well as advanced mathematical/statistical methods for assessing quality and condition of fruits and vegetables before and after harvest.
