Prof Ray Bright Voegborlo has a PhD in Analytical Chemistry and currently an Associate Professor at the Chemistry Department, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. His interest is in analytical instrumentation; food and environmental safety with special emphasis on pesticides, heavy metals and other toxic residues in food and the environment. He has enormous experience in the installation, operation, maintenance and validation of analytical equipment especially GC, GCMS, HPLC, LCMS and AAS. He is also involved in training laboratory staff in analytical techniques for toxic residues in food, water and soil.

Dr. Genevieve Etornam Adukpo is a Senior Lecturer at the Department of Chemistry, University of Cape Coast. She teaches courses in Organic Chemistry with research interests in natural products and food analysis. Some of her on-going research activities are phytochemical, anti-inflammatory and antioxidant activities of bioactive medicinal plants, assessment of nutritional and functional properties of vegetables and cowpeas, pesticide residue analysis of cowpea and soybeans grown in Ghana. She is also the Coordinator for Advocacy and Outreach at the Centre for Gender research, Advocacy and Documentation (CEGRAD), University of Cape Coast. She has keen interest in Gender-Science, Technology & ICT. As a Co-ordinator for advocacy and outreach at CEGRAD, she has organised and faciltatated lots of gender related activities like Gender Awareness and Gender Analysis workshops, harnessing girls’ potential in science education, Sexual Harassment Training, Engendering of curriculum, among others. She is also involved in promoting and empowering women and girls in STEM and lifelong education. She helped in promoting science education in Ghana through the Ghana Science Association. She is a member of the °ÄÃÅÁùºÏ²Ê¿ª½±¼Ç¼ (°ÄÃÅÁùºÏ²Ê¿ª½±¼Ç¼) and PACN.

He obtained his first degree in Chemistry from the University of Ghana in 1976. He got his M.Sc. in Analytical Chemistry from McMaster University in Hamilton, Canada. His research work was on the chemical derivatization of nucleosides for chromatography and mass spectrometry.

His Ph.D. research was on the radical chemistry of Alpha-hydroperoxydiazenes, studying the synthetic applications and mechanisms of the reactions. He obtained his Ph.D. from McMaster University as well. He joined the then Biomedical
Mass Spectrometry Unit of McGill University, Montreal, where he worked on developing methods for GC-MS analysis of organic acids in the urine of sick children.

Dr. Osei-Twum moved to join the Research Institute of King Fahd University of Petroleum & Minerals, Dhahran, Saudi Arabia, in 1989 and worked on a variety of projects. He used NMR to study nucleoside derivatives, and GC-MS (and MS) on natural products as well as organometallic compounds.

His final seven years in Saudi Arabia was spent at the Saudi Basic Industries Corporation where, using chromatography and mass spectrometry, he worked on solving problems for the various companies of the Corporation.

Dr. Osei-Twum is currently a Visiting Scholar at the Department of Chemistry, School of Physical and Mathematical Sciences, University of Ghana, Legon, Accra.
