Professor Isaac Kwasi Adu is a Ghanaian academic and applied mathematician known for his contributions to teaching, research, and academic leadership in higher education.

He is affiliated with Kumasi Technical University (KsTU), where his academic career has progressed steadily. He served as an Adjunct Senior Lecturer (2019–2021) before transitioning into a full-time role as a Senior Lecturer (2021–2025) in the Department of Mathematical Sciences. In recognition of his scholarly contributions and service, he was promoted to the rank of Associate Professor, effective 1 September 2025.

Between 2021 and 2023, Professor Adu contributed significantly to departmental and institutional development through curriculum review and academic planning committees, particularly in strengthening applied mathematics programs.

In addition to his teaching and research responsibilities, Prof. Adu has demonstrated strong academic leadership and institutional service. He serves as the Head of the Department of Mathematical Sciences and has been an active member of several key university committees. These include the Mathematics Curricula Development Committee (2020), the Scientific/Local Organizing Sub-Committee for the International Conference on Applied Science and Technology (ICAST) (2021), and the IDCE Engineering Mathematics Committee (2021).

Prior to joining Kumasi Technical University, Prof. Adu had an extensive academic career at Valley View University, Ghana. From 2015 to 2021, he served as a Senior Lecturer in the Department of Mathematics. During this period, he also held several important administrative roles, including Vice Rector of the Kumasi Campus (2019–2021) and Graduate School Coordinator (2020–2021). Earlier in his career, he was Head of the Department of Mathematics at the Techiman Campus (2015–2016) and served as Examinations Officer (2014–2015).

His contributions to academia have been recognized through notable awards. In 2015, he received the Vice Chancellor’s Star Award for Best Research Faculty at Valley View University. In 2016, he was awarded the prestigious Chinese Government Scholarship (CSC Scholarship) for foreign students to pursue a PhD in Applied Mathematics in PR China.

Professor Adu’s academic training spans several years of rigorous study. He obtained his PhD in Applied Mathematics (2019), following an MPhil in Mathematics (2011) from KNUST and a Bachelor of Education in Mathematics (2008) from UEW, Ghana. His educational background laid the foundation for his specialization in mathematical modelling.

His research interests focus on applied mathematics and mathematical modelling, with particular emphasis on infectious disease dynamics, environmental systems, fractional calculus and optimal control theory. His scholarly work has contributed to the understanding of complex systems relevant to public health and interdisciplinary scientific challenges.
