Ethiopian Institute of Agricultural Research | Ethiopia
Dejenie Mengistie Yirsaw is an experienced researcher in Animal Molecular Breeding and Genetics with more than nine years of progressive expertise in genomic analysis, molecular biology, and livestock genetic improvement. His work spans selection signature analysis, GWAS, QTL mapping, SNP discovery, molecular characterization, and advanced bioinformatics. Since 2023, he has been coordinating the Animal Biotechnology Research Program at the Ethiopian Institute of Agricultural Research (EIAR–NABRC), where he leads multidisciplinary teams, manages laboratory resources, and drives national-level research collaborations in animal biotechnology. Dejenie holds an MSc in Animal Biotechnology from Addis Ababa University (2019–2021), where he completed a highly rated thesis on Genome-wide Signature of Positive Selection, Breed-Specific SNPs, and Linkage Disequilibrium in Ethiopian and European Beef Cattle. He also holds a BSc in Biotechnology from the University of Gondar (GPA 3.61/4.0). His laboratory and computational skills include DNA/RNA extraction, PCR and qPCR optimization, SDS-PAGE, gel electrophoresis, molecular marker analysis, cell culture techniques, and advanced statistical and bioinformatics analysis using R, Linux, SPSS, TASSEL, Haploview, Structure, and MapChart. He has led projects on both animal and plant biotechnology, including developing in vitro propagation techniques for fruit crops (apple, plum, peach) and potato varieties. Dejenie has published widely in peer-reviewed journals on topics such as genetic diversity, selection signatures, growth trait genetics, SNP identification, embryosex determination, DGAT1 gene variation, and egg quality traits, contributing significant insights into livestock improvement. His publications appear in Animal Gene, BMC Genomic Data, Journal of Food Processing and Preservation, Global Journal of Animal Scientific Research, and others, with additional manuscripts under review. He has received advanced professional training in bioinformatics, epigenetics, genetic mapping, animal DNA isolation, experimental design, R-software, and participated in the 2024 Juncao Industry Seminar in China. Dejenie is an active member of the Ethiopian Society of Biotechnology (ESoB) and the Ethiopian Society of Animal Production (ESAP), contributing to national research development in genomics and animal breeding. His research interests include molecular and evolutionary genetics, epigenetics, genome editing, computational genomics, and sustainable livestock improvement. Fluent in Amharic and English, he is committed to advancing innovative genetic and molecular solutions to improve productivity, resilience, and sustainability in Ethiopian livestock systems.
