For Mr. Mpho Edwin Tsie, research has never been confined to the laboratory. As the founder of AquaPure Innovations and a PhD candidate in Chemical Engineering at the Botswana International University of Science and Technology (BIUST), his work is driven by a clear purpose: developing sustainable water purification technologies that can address the growing challenges of water scarcity affecting municipalities, mining operations and rural communities.
That mission recently took him to Romania through the Erasmus+ mobility programme, where he joined researchers at Babeș-Bolyai University (UBB) to strengthen his expertise in advanced experimental design and process optimisation. The experience reflects BIUST’s growing commitment to international research partnerships that expose students to world-class facilities while equipping them to develop solutions for Botswana’s most pressing development challenges.
For Mr. Tsie, the international attachment was more than an academic exchange. It was an opportunity to broaden his perspective as a researcher and experience how scientific collaboration transcends borders.
Immersing himself in a new research environment challenged him to think differently, adapt quickly and approach complex scientific questions with greater confidence. Working alongside leading researchers also introduced him to advanced methodologies, including Design of Experiments (DoE) and process simulation techniques that are transforming how scientific investigations are conducted.
These newly acquired skills are directly relevant to his doctoral research, which focuses on developing multifunctional composite materials for water purification using waste materials and naturally occurring plants.
The research addresses a challenge that continues to shape Botswana’s development agenda. As a semi-arid country, Botswana faces increasing pressure to ensure reliable access to safe, affordable and sustainable water supplies. Conventional treatment technologies are often expensive and rely heavily on imported chemicals, creating opportunities for locally developed alternatives that are both environmentally friendly and economically viable.
Mr. Tsie’s research seeks to unlock that potential by investigating natural and waste-derived materials that can be transformed into efficient water purification products. By integrating advanced experimental design techniques into the research process, he is able to identify optimal production conditions more efficiently, reducing both development costs and the time required before technologies can be tested on a larger scale.
The approach represents a significant shift from traditional trial-and-error experimentation towards data-driven research capable of delivering faster and more reliable results.
One of the defining moments of his Erasmus+ attachment was gaining access to state-of-the-art laboratory facilities, where computational modelling could be integrated seamlessly with laboratory experimentation.
Rather than relying solely on repeated physical testing, advanced software tools allowed him to simulate extraction processes, predict performance and compare projected outcomes with published scientific literature before laboratory validation. The experience demonstrated how digital technologies are reshaping modern research by improving accuracy while significantly reducing the resources required to reach meaningful scientific conclusions.
Working with distinguished faculty members in the Department of Chemistry and Chemical Engineering at UBB reinforced the importance of rigorous scientific methodology, open communication and knowledge sharing. The experience highlighted that today’s scientific breakthroughs increasingly emerge through international collaboration, where expertise from different institutions and disciplines converges to solve complex global problems.
For Mr. Tsie, these collaborations have strengthened not only his technical capabilities but also his appreciation of research as a collective endeavour driven by shared purpose rather than individual achievement.
While the Romanian experience provided exposure to cutting-edge facilities and international expertise, he credits BIUST with laying the academic foundation that enabled him to maximise the opportunity.
Through rigorous postgraduate training, practical problem-solving and continuous mentorship within the Department of Chemical, Materials and Metallurgical Engineering, BIUST equipped him with technical competence and confidence to contribute meaningfully within a leading European research environment.
The University’s emphasis on research excellence and international engagement ensured that he arrived prepared not only to learn from global experts but also to represent Botswana’s growing scientific community with distinction.
His journey also reflects BIUST’s broader vision of producing graduates whose research extends beyond academic publications to address real societal needs. As founder of AquaPure Innovations, Mr. Tsie is already translating scientific knowledge into practical solutions designed to improve water treatment for communities, municipalities and industry.
By combining entrepreneurship with research, he demonstrates how innovation can bridge the gap between laboratory discoveries and technologies that improve lives.
Looking ahead, he encourages aspiring researchers to view postgraduate study not simply as a qualification, but as an opportunity to tackle challenges that matter.
He believes BIUST provides an environment where curiosity is nurtured, mentorship is readily available and international collaborations create pathways for students to engage with the global scientific community. Equally important, he urges young researchers to embrace unfamiliar methods and remain open to new ideas, recognising that innovation often begins beyond one’s comfort zone.
