Botswana International University of Science & Technology - BIUST

Biology & Biotechnological Sciences


Welcome to the Department of Biological Sciences and Biotechnology within the College of Sciences at BIUST. Our goal is to advance knowledge in understanding life and its different forms, and apply the acquired knowledge in developing bio-based processes and products. Accordingly, our Biological Science courses equip students with knowledge and skills in studying life and its different forms.

The Biotechnology courses build on these skills and knowledge acquired in Biological Sciences to provide students with practical skills and knowledge in manipulating and exploiting biological systems in order to develop products of economic value, processes and solve challenges in the environment, agriculture, health, manufacturing industries etc. while putting strong emphasis on sustainable utilization, management and restoration of biobased resources.  

HOD's Welcome

Thank you for your interest in the Department of Biological Sciences and Biotechnology! It is indeed my pleasure to take you through the Department’s programmes and activities. If you are a potential student, we hope you find the information here helpful in reaching a decision on your future studies with us and  if you are an interested visitor, we would appreciate hearing from you.

Biology (the study of living organisms) is a dynamic and fast evolving discipline undergoing  rapid development  never witnessed before, driven by advances in molecular biology, biotechnology, bioinformatics and other related disciplines. Our courses at both undergraduate and postgraduate in Biological Sciences (Microbiology, Zoology, Botany, Cell Biology and Developmental Biology, Biochemistry)  and Biotechnology  (Molecular Biology, Genetic Engineering, Bioprocess Engineering, Genomics and  Bioinformatics,  Cell and Tissue culture Technology, Environmental Biotechnology, Industrial Biotechnology, Applied Entomology, Applied Immunology) will provide students with knowledge and skills to advance knowledge in the field  as well as solve socioeconomic problems.

We are privileged to have faculty with diverse scientific interests which provides a wealth of options from which students can select a topic area for their research. Our faculty conduct research in a wide array of life sciences sub-disciplines, tackling problems in areas ranging from molecular biology, applied entomology, tackling antibiotic resistance, applied metagenomics in searching for novel biomolecules and, developing enzyme based processes for the synthesis of bioactive molecules, multi-bioresponsive biomedical materials, functional materials to biosensor. 


If you are a prospective student, I urge you to go through our courses and research activities, come visit us when you can and see the exciting things happening here, feel free to e-mail any faculty member, administrative or technical staff- anyone will be glad to answer your questions or put you in contact with someone who can assist you.

          Dr. Rantong graduated with his Bachelor of Science in Agriculture from Botswana College of Agriculture in 2007. For his honors project, he studied several cultivars of Moringa oleifera to determine the cultivar that is best suited for the local conditions.
        • Richard MazebediRichard MazebediTeaching Instructor
          My research interests lie in the relationships between ecological communities, environmental parameters and the ecosystem processes. Organisms perform important ecological processes to the habitats in which they live.
        • Bokhutlo ThethelaBokhutlo ThethelaTeaching Instructor
          My graduate research work was on life-history and stock assessment of clarias gariepinus in the Okavango Delta, Botswana. I have since been working on aspects of the population biology of this species to seek opportunities for commercially harvesting it in a sustainable manner since it is currently abundant and underutilized.

Postgraduate Students

      • Batendi NdunaMr Batendi Nduna
        Mr Nduna’s MSc research which he studied at University of Leeds was on the ingress of water into biopolymer films based on mathematical model and theoretical calculations. His recent research interests is in Food Microbiology focused on characterisation of bacteriocins produced by lactic acid bacteria (LAB) from fermented Foods and their application meat..
      • Lindiwe TlhalerwaMs Lindiwe Tlhalerwa
        Ms Tlhalerwa research focuses on the diversity of bacterial microbes in the atmosphere in urban areas, factors that affect the concentration of airborne bacteria and comparing the distributions of airborne bacteria in the two major cities of Botswana
      • Ms Oaratwa MashiqaMs Oaratwa Mashiqa
        Ms Mashiqa's area of research is to isolate and characterize biofilms in the water distribution systems of Botswana from production till end points in my case hospitals.
      • Ms Gorata OaitseMs Gorata Oaitse
        Botswana having started its antiretroviral therapy in 2002, makes it one of the first and longest country in Africa to administer HIV medication. This makes it to be vulnerable to treatment failure and being a developing country with limited resources, it uses clinical and immunological indicators recommended by WHO to monitor treatment failure.Gorata's studies wants to see the proportion of people that might be switched unnecessarily without medication failure
      • Reyard MutamiswaMr Reyard Mutamiswa
        His research interests lie in a range of themes surrounding terrestrial insects and their environmental adaptations, including eco-physiology, tritrophic interactions, invasiveness and sustainable pest management in the face of climate change.
      • Mr Honest MachekanoMr Honest Machekano
        Honest Machekano is PhD research student in Applied Entomology under the Eco-Physiological Entomology laboratory. Coming from a broader BSc Honours in Agriculture (Crop Science) background, Honest decided to narrow his research focus on Entomology, which saw him enrolling for an MSc in Tropical Entomology (funded by RUFORUM) where he graduated with a merit from the University of Zimbabwe.
      • Ms Eva MoengMs Eva Moeng
        Eva's area of research will look into a tritrophic interaction between host plants, stem borer species and their parasitoids. One of the major challenge is the Lepidopteran insect pest complex. Controlling the stem borers by the use of chemical insecticides have become a major problem as they tunnel themselves in the stems making it difficult for the insecticides to reach them.
      • Ms Nonofo GotchaMs Nonofo Gotcha
        Her research area of interest is the use of chemistry knowledge and techniques to understand and solve biological problems. She has a Bachelor of Science Degree in Biology and Chemistry from University of Botswana. Her passion for research developed during her fourth year project, in which she determined vitamins in Lippia javanica, locally known as Mosukujane using HPLC.

      • Mr Rebaone MotswagoleMr Rebaone Motswagole
        Mr Motswagole is currently working with Bactrocera invadens biology and how it likely shapes establishment in Botswana. Specifically, his research is aimed at finding the current distribution of B. invadens, and how thermal biology is likely to shape its invasion potential and hence its distribution and abundance in Botswana and beyond.
      • Mr Monamodi KesamangMr Monamodi Kesamang
        His study is concerned with investigating the ecology and diversity of antibiotic resistance plasmids belonging to different incompatibility groups using bioinformatics.  Under Dr Teddie O. Rahube's supervision they hope to use a data set of nearly all known natural plasmids from online databases to determine potential links of how different classes of antibiotic resistance genes are transferred across different environments due to plasmid replicon type.
      • Ms Kesego TapelaMs Kesego Tapela
        The issue of increasing antibiotic resistance in pathogenic bacteria is a global emergency and government needs to be aware of its social, economic and health implications. Kesego's study aims to examine the extent of environment contamination through the use of partially/untreated effluent from Glen Valley and Palapye wastewater treatment facilities in Botswana and the impact on the ecology of microorganisms in the soil receiving effluent wastewater following irrigation.
