Speakers
Dr. Ugochukwu “Ugo” Ikeogu is a Post-doctoral Research Associate at Cornell University in the Section of Plant Breeding and Genetics. He holds both a Bachelor’s degree in Agronomy and Crop Science and Master’s in Plant Breeding and Genetics from Nigeria’s Michael Okpara University of Agriculture, Umudike, where he worked on Soybean adaptation and improvement. His PhD research at Cornell University focused on high throughput phenotyping, the use of genomic information and efficient statistical tools in speeding-up genetic gain in cassava. Ugo pioneered the use of portable visible and near-infrared spectrometer (Vis/NIRS) for rapid and standardized phenotyping of quality traits in cassava using linear and non-linear calibration models and assisted in developing strategies and methods for the implementation of genomic selection and other tools for cassava improvement. He is currently working as a Post-doc on high-throughput phenotyping using thermal and hyperspectral imaging tools, transcriptomic and metabolomics profiling of stress responses in Setaria.
