Keynote Speakers

Dr. Wieland Brendel

Abeba Birhane


Bio: Abeba Birhane is a cognitive scientist researching human behaviour, social systems, and responsible and ethical Artificial Intelligence (AI). I recently finished my PhD, where I explored the challenges and pitfalls of automating human behaviour through critical examination of existing computational models and audits of large scale datasets. She is a Senior Fellow in Trustworthy AI at Mozilla Foundation. I am an interdisciplinary researcher and my research interests sit at the intersection of cognitive science, AI, complex science, and theories of decoloniality. I am also an Adjunct Lecturer/Assistant Professor at the School of Computer Science at University College Dublin, Ireland.

Dr. Wieland Brendel

Wieland Brendel


Bio: Wieland Brendel received his Diploma in physics from the University of Regensburg (2010) and his Ph.D. in computational neuroscience from the École normale supérieure in Paris (2014). He joined the University of Tübingen as a postdoctoral researcher in the group of Matthias Bethge, became a Principal Investigator and Team Lead in the Tübingen AI Center (2018) and an Emmy Noether Group Leader for Robust Machine Learning (2020). In May 2022, Wieland joined the  Max-Planck Institute for Intelligent Systems as an independent Group Leader. Besides working on robust, generalisable and interpretable machine vision, he co-founded a nationwide school competition ( and a machine learning startup focused on visual quality control (


Title: A more principled way towards machines that see the world like humans

Abstract: Machines perceive the world very differently from humans. This gap between humans and machines has narrowed little in the past years, despite even the recent emergence of impressive large-scale foundation models. In this talk, I discuss our recent systematic work to unravel the hidden assumptions underlying existing representation learning techniques and to develop new techniques that leverage the compositional 3D nature of our visual world in a more principled way.

Dr Samson Gejibo

Samson Gejibo


BioSamson Gejibo is a cloud security architect based in Toronto, Canada. Samson architected and developed an IoT Service Platform for Toyota and a distribution management system for Honda Canada. He also architected cloud-based software solutions to retails and logistics firms. Currently, he is building a secure credit and payment solution for an e-commerce giant based in Texas. In the past, Samson worked for Ericsson Sweden, the UN millennium village, and the Norwegian Red Cross. He also taught advanced software security courses at the University of Bergen. He contributes to open-source communities such as the Open Web Application Security Project (OWASP) and Linux Foundation. Samson received his Ph.D. in advanced Security systems from the University of Bergen (2015), Norway a master's degree in Information security from the Royal Institute of Technology (2010), an MSc from the then CTIT and a bachelor's in Electrical Engineering from Jimma University (2005).


Title: Security for a Networked Society in Africa

Abstract: Society in Africa is closely connected through the rapid growth in mobile communications technology, cloud computing, and wide cellular coverage. These infrastructures created an opportunity for businesses to fill the demand for low-cost healthcare solutions, payment services, e-commerce, and agro- industry. The presence of global cloud providers such as Microsoft Azure and Amazon cloud in the continent, and also local data centers are accelerating digital service offerings. One key area that the continent is left behind is data security and security often comes as an after thought, instead of being planned early in the design of ICT infrastructure projects. In this keynote, the speaker will discuss strategies that can help emerging digital businesses to build security into the early design of their digital solutions and indicate a way to formulate a needs-based assessment of security for a digital society in Africa. Furthermore, the keynote will present some pointers on how we can carefully plan security legislation and technical regulation by governments, in support of innovative ICT services and industrial development.
