Department of Chemical Sciences

Colleges and Faculties > Independent Faculties > Faculty of Science > Department of Chemical Sciences

The Department of Chemical Sciences enjoys the historical privilege of being one of the foundation departments at the inception of Olabisi Onabanjo University in 1982. The department was established to produce students who are very conversant, in a broad sense, with the theories, principles, and applications of chemistry, so that they could be thoroughly resourceful, adaptive, and innovative in their later employment, whether in the field of chemical research, in universities, in industry, or on their own. 

Vision

The vision is to be a leading Department of Chemical Sciences, renowned for innovative research, exceptional teaching, and impactful community engagement, by producing graduates who, through advances in the chemical sciences, are able to address national and global challenges.

Our History

Find below the list of former Heads of the Department since its inception to date. The Department is similarly grateful to all the scholars for their contributions toward the growth and development stages of the Department.

Academic Programmes

The academic programmes in the department are at both undergraduate and postgraduate levels. At the undergraduate level, students have the option of either coming in for Industrial Chemistry or Chemistry. At both levels, the Department provides training in organic, inorganic, physical, industrial, analytical/environmental chemistry and other aspects of chemistry to stimulate and sustain their interest and enthusiasm in chemistry as a subject and its application in everyday life.

Research Areas

Research in the department includes the following areas:

  • Environmental monitoring and evaluation
  • Green synthesis
  • Biological applications of transition metal complexes
  • Extraction of different essential oils from plants and their biological applications
  • Ethnopharmacology and Phytomedicine
  • Isolation, characterisation, and application of biopolymer
  • Synthesis, characterisation, and application of nanomaterials
  • Haemoglobin reactivity and structural dynamics
  • Biosorption and phytoremediation using natural biomass
  • Thermodynamic studies of metal ion uptake.

Facilities for Student Training

The Department is well equipped with modern facilities to support research and teaching:

  1. Teaching and training laboratories: for conducting chemistry practicals for the organic, inorganic, physical, and analytical/environmental courses
  2. Research laboratories: these are equipped with the necessary equipment, apparatus, and instruments for carrying out research work in natural product chemistry, medicinal chemistry, environmental remediation, nanomaterials, biophysical, bioinorganic, biopolymer synthesis, characterisation, and application.
  3. Lecture Halls and Classrooms: conducive spaces equipped with audiovisuals needed for interactive and effective teaching and learning.

Dr. Oseyemi Omowunmi Olubomehin, an Organic Chemist specialising in Natural Product Chemistry is a Reader in the Department specialising in drug discovery from plants. She obtained her Ph. D. in Pharmacognosy in 2015, and this has enhanced her research as a Natural Product Chemist.
Her research has been extensively on discovering and developing therapeutic agents derived from plants having antidiabetic, antioxidant, and antimicrobial properties. Her expertise is in Phytochemistry, Natural Product Chemistry, Medicinal Plants, and Pharmacology. She has about thirty-seven publications in reputable journals both within national and international space, with twenty-two out of these on the discovery and characterisation of bioactive compounds from plants with potential therapeutic applications.
Dr. Olubomehin’s research has contributed to the understanding of the chemical and pharmacological properties of medicinal plants, shedding light on their potential uses in traditional medicine and validating their traditional use scientifically. This has led to the development of new treatments for the diseases being studied as an answer to the call for alternative therapies.
While she continues to explore the vast potential of medicinal plants in the discovery and development of novel therapeutic agents, utilising her skills in chromatography and spectroscopy, Dr. Olubomehin hopes to pursue collaborative research opportunities to translate findings into practical applications.
As the Ag. Head of Department, she provides strategic direction and leadership, overseeing the development and implementation of chemistry curricula. Since no nation can grow beyond its research output, she is committed to fostering a research environment, promoting interdisciplinary collaborations, and ensuring research integrity. Her vision is to promote the importance of chemistry to various stakeholders, thus advancing the relationships with industry, government, and community partners.
