Computing education research (CER) contributes scientific knowledge about the learning and teaching of computer programming and other areas of computing education; develops software tools, pedagogies, and theoretical models to help computing students and teachers; and evaluates such tools, pedagogies, and models empirically.
CER is an interdisciplinary field at the cross-section of computer science, psychology, and education.
We develop and apply educational technology, learning analytics and educational data mining to improve computing education as well as other fields of education.

Internet has catalysed modern computing to evolve towards distributed architectures rapidly, creating novel technology paradigms like cloud computing and IoT. Computing Systems conducts interdisciplinary research into the infrastructure and systems that support such novel technology paradigms. The research ranges from theoretical, such as distributed systems, distributed system architectures and distributed algorithms to applied such as IoT, Web Services, Analytics, Ubiquitous Computing, Systems for Machine Learning and Distributed Multimedia systems. These research areas are intersectional in their design, underlying infrastructure and service delivery constraints. Focus areas include IoT management, networking and applications, vehicular networks, edge computing, web service design and analytics, system analytics, video delivery optimization and low latency distributed multimedia systems including cloud/edge rendered XR. The research uses empirical methodologies to leverage human factors like human visual system and human computer interaction in system design, specifically in cloud rendered XR and ubiquitous computing.

Digital Ethics, Society and Policy (Digital-ESP) brings together diverse researchers, scholars and practitioners engaging at the intersection of technology, social science and policy concerns in a societal context. From a Computer Science perspective this is a crucial area for critically interrogating the ethics and values embedded in technology, the interplay with society, and the role of policy-making to better understand and mediate positive or adverse impacts.
Increasingly, contemporary concerns with emerging technologies such as AI, surveillance, cybersecurity, robotics, drones and autonomous systems in society have been much debated. However, issues of gender and racial equity, Global South inclusion, political participation, democracy, protest, civic engagement, crisis, and sustainability in technological contexts, are also critical topics of emphasis for this area.
Digital-ESP is focused on understanding the societal impact of technologies in a transdisciplinary manner (i.e. drawing on research conducted at the intersection of different fields and engaging diverse stakeholders), while proposing critical guidance and policy interventions.

The goal of this research area are 1) to create new technologies, designs, analysis methods for the development of secure and private computing and communication systems, and 2) advance the fundamental scientific knowledge in security engineering, including human factors.
These new technologies aim either to deter, prevent or detect malicious attacks and they should be, at the same time, secure, privacy-preserving, easy to use, and inexpensive to deploy. As is typical for security research, our results also include the discovery of novel attacks and previously unknown classes of vulnerabilities in existing systems.
Security against malicious attacks is a basic requirement for all networkconnected services and products, and scientific research can provide both fundamental understanding of the security issues and practical solutions that enable product development.

Visual computing studies the creation and understanding of images, shapes, and three-dimensional spaces by computational means. As we seek to increase our understanding of not just how to create and analyze images and sounds, but also how we humans perceive, react to, and interact with them, research in visual computing is of an increasingly interdisciplinary nature.
