Bernardo Rodrigues

Bernardo Rodrigues was born in the city of Malanje, North of Angola and studied at the Pedagogic University Enrique José  Varona in Cuba where he earned the Graduate in Mathematics and Education in 1991. In 1991, he was appointed as a junior lecturer to the Mathematics Department at Universidade Agostinho Neto, Luanda, and in 2004 became a senior lecturer. In 1996 he moved to South Africa, where at the former University of   Natal, in Pietermaritzburg he obtained an Honours degree in pure Mathematics (1997), an MSc in Mathematics (theory of group extensions) in 1999 and a PhD in Mathematics (Algebraic Coding Theory) in 2002, the latter under the supervision of Jamshid Moori (Natal) and co-supervision of Jennifer Key (Clemson University, USA). He was appointed to the Mathematics Department of Natal University in 2004, where he became an Associate Professor since 2010, under the new merged University of KwaZulu-Natal. In the period 1996 – 2002 he was awarded a DAAD-German Academic Exchange Scholarship and the Angolan Ministry of Petroleum to take up graduate studies, and in 2017, he was the recipient of a Fulbright Scholar Award. During the period 2016 – 2018 he was awarded two scholarships by the European Union to participate in two Erasmus Mundus Plus Exchange Programmes for scholars. He was also one of three African recipients of the Mentoring African Research in Mathematics programme under the auspices of the London Mathematical Society to take up a partnership with the University of Birmingham (UK). Most recently he was awarded a research fellowship by the Isaac Newton Institute (Cambridge University) to undertake research on problems relating representation theory of finite groups and classification (February to June 2020).

Although his early work concerned the theory of finite groups, in particular the study of the extension problem, his current research interests concern with the inter- play between Algebraic Coding Theory, Finite Simple Groups, Modular Representation Theory of Finite Groups and Combinatorial Design Theory as well as Computational Group Theory and Axial Algebras, including both the concrete and the abstract aspects of these subjects. His recent papers involve modular representation of finite simple groups, by examining problems relating the realization of finite simple groups as permutation groups of automorphisms of linear codes. He also works on problems related with the construction of non-associative axial algebras related to the sporadic simple groups and on applications of graph theory to the transmission of diseases and other societal problems using network models. He became the managing editor of the journal Afrika Mathematika in 2013 and one of three Deputy-Editors since 2018. He has held several visiting positions in several African countries, at universities in Europe, the United States, Australia, New Zealand and most frequently at the University of Birmingham in the United Kingdom. He is an invited professor of the Mathematics Department at Universidade Agostinho Neto in Luanda since 2008.

He completed his training with a postdoctoral internship in the Department of Mathematics at the University of Quebec, in Montreal, under the direction of Professor Carolyn Kieran.  

His contribution to research in mathematics didactics was constant and supported by his publications and his involvement in several professional and scholarly associations  amoung them: Francophone Mathematical Space(EMF), International Observatory of Algebraic Thought (OIPA), the Quebec Mathematical Association (QMA), the Association of African Didacticians of Mathematics ADiMA, etc… .

Professor Adihou conducted many funded and non-funded research projects.  His research was motivaded by his concerns in teaching, and  teacher initial and continuing training. His research focuses on didactic phenomena in teaching and learning mathematics in general and in particular the development of algebraic thought in primary and secondary levels. He is also interested in the difficulties of teaching and learning mathematical concepts. He participated in the design of didactic resources through several collaborations and partnerships. His interests also include the use of mathematical tricks in teaching and learning, the analysis of teacher training systems in mathematics, and the issues related to the initial and in-service training of teachers and mathematics orthopedagogues.
