Dr Adedoyin Titi Amos is a Senior Lecturer and researcher in the Department of Animal Nutrition, Federal University of Agriculture, Abeokuta (FUNAAB), Nigeria. She is a specialist in Monogastric Animal Nutrition with research interests centred on sustainable monogastric animal production, alternative feed resources, and the utilization and valorisation of agro-industrial by-products in monogastric nutrition. She obtained her National Diploma in Animal Health and Production Technology in 2006. She subsequently earned a Bachelor of Agriculture degree in Animal Nutrition with Second-Class Upper Division from the Federal University of Agriculture, Abeokuta, in 2010. Driven by her interest in advancing knowledge in animal nutrition, she obtained a Master’s degree in Monogastric Animal Nutrition from the same institution in 2014 and subsequently earned her PhD in Monogastric Animal Nutrition in 2018. Dr Amos has received competitive research and academic awards and has participated in several collaborative research projects. In 2022, she received the Tertiary Education Trust Fund (TETFund) Institutional-Based Research (IBR) grant, which supported her research in animal nutrition. She has also served as a member of research teams on other competitively funded research grants, contributing to research design, experimentation, data generation, and dissemination of research outcomes. In recognition of her academic and research potential, she was awarded the prestigious TETFund Overseas Scholarship Award to undertake postdoctoral research in Brazil. She carried out her postdoctoral research in Monogastric Nutrition at the Federal University of Mato Grosso, Sinop Campus, Brazil, from 2024 to 2025, focusing on the utilisation of agro-industrial by-products, particularly dried distillers grains with solubles (DDGS), as sustainable alternative feed resources in poultry nutrition. The experience further strengthened her research capacity and international collaborations. Dr Amos's research interests include the development and utilisation of alternative and unconventional feed resources, agro-industrial by-product valorisation, feed processing and bioprocessing, enzyme supplementation, and sustainable nutrition of poultry and other monogastric animals. Her research is driven by the need to identify cost-effective, locally available, and environmentally sustainable feed resources that support efficient animal production. She is a Registered Animal Scientist and a member of the Animal Science Association of Nigeria (ASAN) and the Nigerian Society for Animal Production (NSAP). Through her teaching, research, student supervision, and professional activities, Dr Amos continues to contribute to advances in knowledge and the development of sustainable monogastric animal nutrition and production systems.
