He is a member of the Chemical Society of Nigeria and Royal Society of Chemistry and&nbsp; he has mentored over 100 Postgraduate students. He has over 65 publications and &nbsp;he has won&nbsp; and managed three grants and scholarship. His current research in Analytical and Environmental Chemistry is focused on the development of sensitive novel analytical methods for trace analyses and determinations of organic\/inorganic contaminants in the environment. Specifically, HPLC, GC-equipped with ECD, AAS and UV-Visible spectrophotometric methods are being utilised to detect, identify and quantify emerging contaminants such as Persistent Organic Pollutants, Polycyclic Aromatic Hydrocarbons, and the Potentially Toxic Metals in multimedia samples..&nbsp;&nbsp;<\/span><\/p>\n<p><strong style=\"letter-spacing: 0px;\">Positions, Scientific Appointments, and Honours<\/strong><\/p>\n<p>Professor: University of Lagos, Akoka&nbsp; 2015<\/p>\n<p>Acting Dean, Faculty of Science Dec 2024\/May 2025<\/p>\n<p>Head, Department of Chemistry August 2022-<\/p>\n<p>Member, African Regional&nbsp; Standard Organisation (ARSO)<\/p>\n<p>Editor-in-Chief, Faculty of Science Journal 2019- \uf0d8<\/p>\n<p>Chairman, Faculty BMAS Review Committee 2018 \uf0d8<\/p>\n<p>Senate Representative on the Board of Distance Learning Institute 2018- \uf0d8<\/p>\n<p>Coordinator, Master of Environmental Management (2009 \u2013 2016) \uf0d8<\/p>\n<p>Consulting Environmental Analyst, UNILAG CONSULT 2009- 2014 \uf0d8<\/p>\n<p>Reviewer for: Journal of the American Oil Chemists\u2019 Society<\/p>\n<p>Fresenius Journal of Analytical Chemistry<\/p>\n<p>Environmental Monitoring and Assessment Journal.<\/p>\n<p>Chairman, Standard Organisation of Nigeria (SON) Technical Committee on Draft Standards for Natural waters and Beverages September 2019-Date<\/p>\n<p>TETFund 2022 Grant: Legact Air Pollutants<\/p>\n<p>TETFund 2022 Grant:Air Pollution in Indoor dust<\/p>\n<p>TETFund 2020 Grant: Boiconversion of agro and textile waste to chemicals of industrial use.<\/p>\n<p>5th Nigerian Merit Gold Award for Productivity (2013)<\/p>\n<p>University Central Research Grant: Environmental Oestrogens and Androgens: Occurrence and Biological Effects in Organisms inhabiting the Lagos Lagoon Ecosystem (2011).<\/p>\n<p>Israeli Scholarship Award: Environmental Management Training Programme, Galilee College, Mizra, Israel(2008).<\/p>\n<p>Aldrich Chemical Company: Recognition of work on Garcinia kola and cola acuminata, (1994).<\/p>\n<p>Member, National Technology Forum and Techmart, Wealth Creation through Technology and Commercialisation of R and D Results and Innovations Lagos 2000.<\/p>\n<p><strong style=\"letter-spacing: 0px;\">Selected Most Recent Publications \/Contributions to Knowledge<\/strong><\/p>\n<ol>\n<li>Akinrinade, OE, F.
