Brief Biography: Dr Abolaji Amos Olalekan is a Reader/Associate Professor in the Department of Biochemistry (Molecular Drug Metabolism and Toxicology Unit), Faculty of Basic Medical Sciences, College of Medicine, University of Ibadan. He obtained B.Sc., M.Sc.and Ph.D.degrees in Biochemistry from Obafemi Awolowo University, Ile-Ife (1998), University of Lagos, Lagos (2003) and University of Calabar, Calabar (2010) Nigeria, respectively. Dr Abolaji is currently working on themechanisms by which certain environmental toxins contribute to female reproductive dysfunctions, neurodegenerative diseases and cancer using rodents and Drosophila melanogaster as model organisms. Accordingly, the focus of his research is to proactively detect health risks associated with these toxins and decode the mechanisms of pathogenesis. These would aid in the design of concepts for prevention and possible therapy. Dr Abolaji is a recipient of several awards including 2009 WHO/TDR Travel Fellowship to the Fifth MIM Pan-African Malaria Conference, Nairobi, Kenya; CNPq-TWAS Postdoctoral Fellowship Award at the Department of Biochemistry and Molecular Biology, Federal University of Santa Maria, Brazil (2013-2014); SOT/AstraZeneca/SOT Endowment Fund Travel Award (2015) and 2018 Africa-Oxford Visiting Fellow Award. He is also a recipient of 2018 CRP-ICGEB Grant, Cambridge-Africa ALBORADA Research Grant (2016, 2018) and International Society of Neurochemistry CAEN Grant (2016). He is a member of the Society of Toxicology, Society For Redox Biology and Medicine (SFRBM), European Teratology Society, Genetic Society of America and Neuroscience Society of Nigeria. Dr Abolaji has published seventy (70) papers in different peer-reviewed international journals. Dr.Abolaji is a Team Lead at the Drosophila Research and Training Centre (DRTC, www.drosophilartc.org), Nigeria, a non-profit organization that facilitates the use of Drosophila melanogaster as a cost-effective, alternative animal model for biomedical research and training in sub–Saharan African countries.

In 2014, after a postdoctoral training at the Federal University of Santa Maria, Brazil, Dr Abolaji set up Drosophila laboratory at the University of Ibadan from the scratch https://twitter.com/DrosLabUI. The laboratory is currently well-equipped with state-of-the-art equipment and collaborates with scientists in UK, USA, Germany, Spain, and Brazil. Research
Brief Summary: The research commenced in 2018 following a 3-year grant from International Centre for Genetic Engineering and Biotechnology (ICGEB), Italy. The project is currently in the 4th year (no cost extension). A previous study on the ameliorative role of resveratrol in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson’s disease in D. melanogaster was used as preliminary data to apply for the ICGEB grant. We hypothesized that resveratrol will serve as a therapeutic agent in different genetic models of Parkinson’s disease (PD, Pink-I, Parkin etc.) using Drosophila melanogaster as a model. We are asking the following questions in this research:
ii. What are the actions of resveratrol on oxidative stress and on biochemical features associated with Parkinson’s disease onset?
iii. How can we implement and optimize different biochemical and molecular techniques to validate potential therapy for Parkinson’s disease/symptoms?
iv. How can we monitor molecular changes associated with resveratrol treatment in PD flies?
