Alemayehu Teressa Negawo is a research officer/laboratory supervisor in the feed and forage development program at ILRI. He joined ILRI in June 2015 and his roles are conducting research activities on forage crops, supervision of feed and forage laboratory facilities and provision of daily supports to routine forage genebank activities.

He has Dr.rer.nat. (Doktor der Naturwissenschaften) and MSc (major in Plant Biotechnology) degree from Gottfried Wilhelm Leibniz University of Hannover (Germany), postgraduate diploma from University of Tours, France and BSc degree in Horticulture from Jimma University, Ethiopia. Alemayehu worked as a junior and assistant researcher at Ethiopian Institute of agricultural research and has experience on molecular characterization, tissue culture and genetic transformation of plants, analysis of transgenic plants, detection of GMO and basic skills of bioinformatics and NGS data analysis.

His research interests are the application of NGS, biotechnology and modern molecular biology tools to study genetic resources (e.g., genetic diversity assessment using GBS approach) and to address crop production constraints (e.g., identification of virus, insect resistance, and abiotic stress tolerance, etc) and to enhance conservation and sustainable utilisation of the available genetic resources for selecting high yielding varieties.
