G.S. Peter Castle
One of the founders of modern applied electrostatics research, G.S. Peter Castle has developed tools for addressing real-world issues impacting manufacturing, agriculture, and the environment. His work on electrostatic precipitators including two-stage precipitation and space charge suppression has improved air-cleaning applications. He also developed processes for electrostatic liquid painting and powder coating, which have provided more cost-effective and environmentally friendly solutions compared to conventional industrial painting systems. Castle’s induction charging concept has enhanced liquid deposition of pesticides on leaves, reducing the amount of chemicals that need to be sprayed for improved crop protection. His research concerning contact charging for electrostatic separation of plastics is benefitting the recycling industry.
An IEEE Life Fellow, Castle is a Professor Emeritus and adjunct research professor with the Department of Electrical and Computer Engineering at the University of Western Ontario, London, Ontario, Canada.
