In the dynamic field of root and tuber crop research, my work focuses on sweet potato and cassava with investigating the complex world of viruses and associated diseases, with a primary focus on cassava. Working with a global collection of virus samples from South America, Africa, Brazil, and Asia, I lead research across several key areas: Pathogen Identification and Discovery: We uncover both known and emerging pathogens affecting cassava and other root and tuber crops, including cassava root rot, witches' broom disease, and frog skin disease. Pathogenesis and Host-Virus Interactions: Our research on cassava brown streak and cassava mosaic viruses explores gene-protein interactions, using tools like confocal microscopy to map the spatial and temporal dynamics of infection. High-Throughput Resistance Screening: We apply advanced screening tools to identify resistant cassava germplasm and evaluate the durability of resistance under field conditions. Characterization of Resistance: Using state-of-the-art omics technologies and high-resolution imaging, we investigate the molecular mechanisms underpinning cassava’s immune responses to viral attacks. Virus Elimination and Exclusion: Our translational research focuses on developing practical strategies to eliminate viruses from planting material and control their spread in cassava. A major success has been our contribution to combating Cassava Brown Streak Disease (CBSD) in Eastern and Central Africa—protecting cassava, one of th
