[Research Overview]

• The professor’s work centers on developing devices using 3D printing, robot systems, sensors, and battery technologies for applications in biomedical and environmental sensing, with recent active research in Agritech.

• The fundamental question driving the research is, "Are weeds outsmarting us?" This addresses the challenge of managing weeds that have evolved high adaptability to chemicals in an environmentally friendly and effective manner.

• The proposed solution to climate change is to implement Precision & Autonomous Agriculture.

[Detailed Applications and Research Examples]

Precision Agriculture in the Face of Climate Change

Analysis of the impacts of climate change in regions like British Columbia/Canada and the development of precision and autonomous agricultural strategies to address these challenges.
Lab Research Categories

(1) Drone Data Utilization

  • Use of unsupervised segmentation and information extraction techniques, including measuring plant height with a DBSCAN-weighted k-clustering approach.

(2) Early-Stage AI-Driven Weed Management Robot

  • Integration of YOLO-X with a robotic system to develop a preliminary weed detection and management framework.

(3) Plant Health Monitoring and Autonomous Resource Control

  • Implementation of a sensor-based autonomous irrigation system.

  • Use of a robotic arm for invasive, full-contact diagnostics over 10–15 minutes.

  • Application of gel on electrodes to reduce electrode resistance; monitoring of potential (EP) shifts that increase with water content.

  • Conversion of the EP signal into a 2D image to extract recognizable patterns, with AI predicting plant status through electrophysiological data to drive decision-making for autonomous irrigation.
