Dr. Louis-Ray Harris is a Physics Lecturer in the Department of Physics, Faculty of Science & Technology, UWI. His areas of research interest include Electronics, Electromagnetics, Wireless Communications and RF Propagation. RF Propagation studies how radio waves (a form of electromagnetic wave) behave when they travel through the atmosphere under different conditions - this will help improve communications such as the reliability of mobile phones, radio and TV broadcasting and radio navigation systems. He is also investigating the effects of wireless device use on human health in realistic environments such as in vehicles. This will help improve the safety of devices using electromagnetic waves.
