The postdoctoral researcher will be working in the Cassava Source-Sink Project (CASS), an international collaboration to increase cassava agricultural performance and value. For more information, please see https://cass-research.org/.  In the CASS project we are using metabolic and genetic engineering strategies to develop novel cassava varieties with increased yield and starch production, especially for smallholder cassava farmers to improve their food security. The postdoctoral researcher will be leading a project involving large-scale field experiments for agronomic performance, field UAV phenotyping of cassava growth, photosynthesis measurements in the field, and laboratory analysis of cassava using molecular, biochemical, and
