My background is in marine and soil microbial ecology, with special interest in communities in extreme environments, such as hot springs and brine pools. These organisms harbor novel “biocatalyst” enzymes that can be immensely useful to modern biotechnology, from new molecular tools to novel medications. “White” Biotechnology, the use of biocatalysts for industrial processes, can help make manufacturing processes more efficient and environmentally friendly, help recycle materials that are currently unrecyclable, and, most importantly, help us to produce more environmentally friendly materials in the first place.
Like industry, modern agriculture needs novel solutions to environmental problems such as land degradation, increasing soil salinity, and water scarcity due to current practices. Within the Salt Lab at KAUST, I have been using my biotechnological expertise in the adaptation and genetic engineering of plants for enhanced salt tolerance, with an overall aim to reduce the environmental impact of modern agriculture while maintaining food security.
