During his PhD graduation ceremony, he emerged as the best international student. This award combines with other previous academic and competency awards: best undergraduate student in electromagnetism (2004), best advanced secondary school student in Physics (2002), and best primary school student in punctuality. Between 2015 and 2017, Prof. Maiseli pursued postdoctoral studies at HIT, focusing on the methods and algorithms for efficient and effective computation of distance transforms in digital images. Furthermore, he was promoted to Senior Lecturer on 9th September 2020, and to Associate Professor on 25th September 2023. He lecturers undergraduate and postgraduate students on the following courses: Fundamentals of Signals and Systems, Advanced Analogue Electronics, Image and Video Processing, and Advanced Digital Electronics. Prof. Maiseli supervises undergraduate students and postgraduate students in their final-year projects and research, respectively. He has supervised six (6) master students to graduation, and six (6) PhD students, three of which have graduated. Since 2022, Prof. Maiseli has been serving as an external examiner of postgraduate students at the African Center of Excellence in Internet-of-Things, University of Rwanda, Rwanda.
Prof. Maiseli, outside professional activities, likes touring historical sites and visiting game reserves. He spends time in meditation and critical thinking on different aspects of life, and enjoys creating and sharing social and educational materials with the community.
