Joyce Nakayenga holds a Doctor of Philosophy in Engineering (Civil and Environmental Engineering) from Hiroshima University, Japan, and a Master of Engineering in Civil and Environmental Engineering from Hiroshima University. Before that, she obtained a first-class Bachelor of Science in Civil and Environmental Engineering from Uganda Christian University, Uganda. Due to her excellent performance, she has since won 3 awards, including the Academic Excellence Award from the Uganda Christian University, The Academic Encouragement Award, and the 2022 Academic Excellence Scholarship from Hiroshima University, Japan. She was also awarded the Mext Japanese Government Scholarship, which funded her Japanese Language Course, Masters, and PhD. Nakayenga has also recently been nominated among the Top 40 under 40 by the New Vision Uganda

She has 3 years of experience working for Universities and the Government of Uganda. Currently, she is employed as an Assistant professor of Collaborative Research at Hiroshima University, where she researches carbon capture and storage technologies in collaboration with Fujita Corporation. She has worked at the Ministry of Gender, Labour and Social Development, Uganda, as an Inspector of General safety, where she was responsible for regulating occupational safety and health of workers, particularly those in the construction sector. She also worked as a Student Demonstrator/Tutorial Assistant at the Uganda Christan University, mentoring Civil Engineering and Environmental Science students.

She has published several research papers on various research topics, including Engineering education, Waste reuse in the construction industry, and other geotechnical engineering topics, such as the stability of shallow slopes.

Below is the list of her publications
