Dr Paramsothy (Jeya) Jeyakumar PhD

Senior Research Officer in Soil Chemistry

Doctoral Supervisor
School of Agriculture and Environment

I describe myself as a soil scientist, with specific expertise in the subject area of environmental chemistry. My research objectives align with enhancing the primary sector production and productivity while maintaining soil and water quality, and food safety. My current research projects study heavy metals and essential micronutrients in agricultural products and their effects on the food chain. I developed a great deal of expertise in using metal speciation to assess the bioavailability of trace elements (TE) in soil, and their effects on plants and soil microbial activity.
