Dr. Lee is working on developing sensing systems for specialty crops for precision agriculture in Florida. His areas of specialization include: sensing systems, precision agriculture, farm automation, Global Positioning System (GPS), 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 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, citrus black spot (CBS) disease detection, and strawberry flower detection for yield prediction.


Dr. Lee specializes in precision agriculture, GPS/GIS, variable rate fertilizer application, yield mapping, machine systems design, sensor development, instrumentation, machine vision/image processing, NIR spectroscopy, and farm automation.
