Research theme:Elucidation of Aegilops tauschii contribution to heat and drought tolerance diversity in bread wheat through genomics and metabolomics
Obtained (planned) degree/date:Doctor of Philosophy (Ph.D. Agriculture) September 2021


I was born and raised in Nigeria and came to Tottori University, Japan in 2015 as a research student. Then I enrolled in a master’s program in 2016 and went on to obtain a Ph.D. degree in September 2021.

Abiotic stresses such as heatwaves and drought episodes have been a persistent problem hindering global agriculture. This problem has been exacerbated by climate change and the rising global population. It is, therefore, necessary to develop new methods to ensure sustainable agricultural productivity. To this end, my Ph.D. thesis was titled “Elucidation of Aegilops tauschii contribution to heat and drought tolerance diversity in bread wheat through genomics and metabolomics”.

My research interest is in breeding climate-resilient crops, especially wheat, using genomic, physiological, and metabolomic tools. I am currently working as a Project Researcher in Arid Land Research Center, Tottori University, Japan, where I conduct translational research for heat and drought resilience in bread wheat grown under field and controlled conditions.

I am experienced in plant breeding, population genetics, plant physiology, and metabolite analysis; familiar with LC-MS/MS, DArTseq genotyping, GWAS, RT-qPCR, LI-COR, genotype-by-environment interactions, and many bioinformatics and statistical software. I have good leadership and communication skills, innovative, and excellent in teamwork.
