Agricultural and Biological Engineering

Dr. Wonsuk "Daniel" Lee

Professor, Machine Vision and Precision Agriculture
Fellow, American Society of Agricultural and Biological Engineers
Precision Agriculture Laboratory

Dr. Lee is working on developing sensing systems for specialty crops for precision agriculture in Florida. His areas of specialization include: sensing systems, artificial intelligence, precision agriculture, farm automation, Global Navigation Satellite System (GNSS), geographic information systems (GIS), near-infrared spectroscopy (NIRS), image processing, machine vision, yield monitoring/mapping, variable rate fertilizer application, instrumentation, machinery, and agricultural mechanization. He draws from all these areas to develop solutions for a wide range of agricultural problems.

At the heart of Wonsuk "Daniel" Lee's expertise is the application of sensors, devices which "see" beyond the range of human senses and can deliver information to computers and other devices. Lee's skills also include a wide range of supporting technologies and novel applications, such as strawberry flower and fruit detection for yield prediction, two-spotted spider mite (TSSM) detection using deep learning, strawberry fruit bruise detection, autonomous weed control systems, immature green citrus fruit detection, autonomous yield mapping for immature citrus fruit, apple Marssonina blotch (AMB) disease detection, citrus greening disease (Huanglongbing) detection, blueberry fruit detection for yield mapping, and citrus black spot (CBS) disease detection.
