Biography

Dr Jarishma K. Gokul is a lecturer in the Department of Plant and Soil Sciences. She has had a steady research focus on microbiology, molecular biology and systems biology of polar and temperate terrestrial and marine landscapes using ‘omics techniques, and more recently, has been involved in establishing the seed-soil-plant-food-human microbiome nexus with Prof. Lise Korsten in the Centre of Excellence in Food Security.

Dr Gokul currently co-ordinates the microbiome-based research activities in the AgriMicrobiome Research Group, within Plant Pathology, and has recently been named in the top #InspiringFiftySA women in STEM. Her research is focussed on agricultural soil and plant microbiomes which involves aligning existing genomic-based soil, water and fresh produce microbiome projects to understand agricultural microbiomes as it relates to food production and health. She also leads the recently developed indigenous fruit microbiome research area as part of funding garnered from the UP Research Development Program (RDP) and was a fellow in the 2021 - 2022 cohort of the ARUA-UKRI GCRF Food Systems Research Network for Africa (FSNet-Africa)Dr Gokul additionally contributes to previous and ongoing research towards understanding the impacts of climate change on Arctic glaciers, Antarctic permafrost, soils and Southern Ocean deep sea microbiomes as a member of the Centre for Microbial Ecology and Genomics (CMEG).
