Biography: 

Dr. Hakeem Olalekan Shittu is currently an Associate Professor in the Department of Plant Biology and Biotechnology, Faculty of Life Sciences, University of Benin, Benin City, Nigeria. He obtained his B.Sc. (Botany) with a First Class (Hons.) Division in the Department of Botany (now Plant Biology and Biotechnology), University of Benin, Benin City. He was retained in the same department as a Graduate Assistant in 2000 after his National Youth Service Corp (NYSC). In the following year, he got the Federal Government of Nigeria scholarship to pursue his M.Sc. Degree in the areas of Cellular and Molecular Biology, in the same department. In 2004, he was awarded the Canadian Commonwealth Scholarship and Fellowship Plan to pursue a Ph.D. Degree (Molecular Biology and Genetics) in the Department of Molecular and Cellular Biology, University of Guelph, Ontario, Canada. After his Ph.D. program, he did a Post-Doctorate Fellowship in the same department. He is also a Fellow of the Linnean Society (FLS) of London, United Kingdom. Dr. Shittu H. O. has attended several local, national and international conferences in Nigeria, Canada and the United States of America. He has numerous scientific publications in reputable national and international journals. He is also a seasoned public speaker, who has earned several international awards in public speaking career and won several prizes in speech contests. His area of research is in Molecular Plant Biotechnology.
