In 1990, Asemota moved to Jamaica to take up a position as Associate Honorary Lecturer at the University of the West Indies. She was appointed Lecturer in 1996, and promoted to Senior Lecturer in Biochemistry and Biotechnology in 1998. In 2003, Asemota was promoted to Professor of Biochemistry and Molecular Biology. She was Full Professor at the Shaw University, North Carolina from 2005 to 2012. During this time she was Head of the Nanobiology Division of the Shaw Nanotechnology Initiative at the Nanoscience and Nanotechnology Research Centre from 2005 to 2009, Nature Sciences Biological Sciences' Program Coordinator from 2009 to 2010, and Chairman for the Shaw UniversityInstitutional Review Board from 2006 to 2009, Senator for the Shaw Faculty Senate between 2007 and 2012, Core Director of the Faculty Research Development at the NIH- Research Infrastructure for Minority Institutions and as IRB Administrator between 2010 and 2012. In 2013, Asemota was appointed Director of the Biotechnology Centre, a research unit at the University of the West Indies with a focus on biotechnology-based enterprises. At the time of her promotion to Professor in 2003, Asemota was a member of the Caribbean Biotechnology Network, the Biochemical Society of Nigeria, the Third World Organisation for Women in Science, and the Nigerian Association of Women in Science, Technology & Mathematics. She was a Fellow of the American Biographical Institute, a member of the National Geographic Society, the Nigerian Institute of Food Science and Technology, and the New York Academy of Science.
Research
Asemota conducted PhD research at the University of Benin and Frankfurt University, where she studied the molecular genetics and metabolism of the browning of yam tubers in storage. Upon moving to Jamaica, prompted by ongoing problems with production and storage in the Jamaican yam industry, Asemota continued researching yams, founding the multidisciplinary UWI Yam Biotechnology Project. Initially, Asemota investigated the biochemical effects of removing yam heads at harvest, a common farming practice in Jamaica. Over the ensuing decades, Asemota's research team has investigated many aspects of yam biochemistry and physiology, from DNA fingerprinting studies of Jamaican yam varieties to the carbohydrate metabolism of yam tubers in storage. In addition to her work on yam production and storage, Asemota has studied the metabolic effects of yams and yam-derived products on animal models of diseases such as diabetes. More recently, the Yam Biotechnology Project has moved towards a 'farm to finished products' strategy, with the goal of producing yam-based food, medical, and biofuel products to benefit the Jamaican economy. She has also applied similar research techniques to other types of tropical crop. Asemota has served as Principal Investigator for the National Institute of Health and National Science Foundation grants. She has lectured undergraduates, postgraduates and postdoctoral levels worldwide, and has supervised or advised at least 30 postgraduate students in Biochemistry or Biotechnology. She has over 250 publications, and owns four patents from her research.
Outreach activities
Asemota has undertaken outreach research with Jamaican farmers, experimenting with lab-derived yam planting materials in their fields, and reviving 'threatened' Jamaican yam varieties.
International consultancy
Asemota has a long history of international consultancy in matters of food security and biotechnology. She was an international technical expert for the European Union, and served the United Nations Technical Cooperation among Developing Countries Programmes as International Technical Cooperation Programmes. She served as an International Biotechnology consultant to the United Nations Food and Agriculture Organisation from 2001. This included consulting for the International Technical Cooperation for Syria with the Developing Countries Programmes in 2001 and as technical lead on food sufficiency for the National Seed Potato Production Programme in the Republic of Tajikistan between 2003 and 2007. She periodically serves the UN-FAO Seed Production Programmes as an International Consultant.
