Our Research

The team in the Advanced Post-Harvest Technology addresses the gap in post-harvest handling and storage of produce and grains. They are developing post-harvest engineering solutions using advancements in sensing, automation, IoT, cloud computing, artificial intelligence (AI), machine vision, hyperspectral imaging and mathematical modeling.

Advanced Post-harvest Innovation program

Dr. Chandra Singh joined the college’s Centre for Applied Research, Innovation and Entrepreneurship (CARIE) as its first applied research chair in Agricultural Engineering and Technology in the summer of 2019. Dr. Singh’s work will include the creation of an Advanced Postharvest Innovation program. The program will be dedicated to building partnerships with the agriculture industry and researching new ways to handle and store crops after harvest in order to minimize post-harvest losses.
