'The effect of sediment on flood hazard and risk in large dynamic river systems’
My research involves numerical modelling of flood hazards and geomorphology. In recent years I have been working on interdisciplinary projects exploring flood risk in Nepal. In the alluvial plains in Nepal, over the past decade early warning systems and the construction of flood protection structures have helped to reduce the consequences of monsoonal flooding. However, sediment transport is often neglected when designing these projects. In this talk I will discuss insights we gained from community engagement work in the Karnali River, Nepal, and demonstrate the importance of accounting for sediment dynamics when considering flood risk in sediment laden river systems.

‘Cybersecurity in next generation mission-critical systems’
I am Senior Lecturer of Computing Science leading the Cybersecurity Research theme at the School of Computing Science. My area of research revolves around data-driven resilience and security for Internet-enabled cyber-physical infrastructures. My philosophy is in designing algorithms and networked systems with strong theoretical foundations and in providing practical, data-driven implementations that are deployable in the real world. In the last 3 years I have been focusing on the security and resilience challenges resulted by the intersection of the IoT with Critical National Infrastructures (CNI) spanning across multiple sectors (e.g., energy, utilities, defence) that have been under the scope of various nation-sponsored or third-party cyberwarfare activities. I am in the lookout for collaborators working with real Operational Technology (OT) systems (e.g., automation, manufacturing, space missions, satellite communications) that can provide me with distinct use cases in which cybersecurity is of importance and target medium-to-long-term funding opportunities.

‘A hollow future for engineering structures: Design and analysis principles’
From the Egyptian, Roman to the Victorian era, important engineering structures were built "solid" for strength and durability. Although many such structures have passed the test of time and therefore validate the underlying design philosophy, they may not always represent the most efficient way of utilising materials. Due to the unprecedented pressure on sustainability and global focus on net-zero, using less material for future engineering structures is mandatory. The rise of 3D printing technology provides a timely solution towards creating "hollow" or "porous" structural members, which have the potential to utilise lesser materials compared to their equivalent solid counterparts. However, the mechanical behaviour of such hollow structures must be understood well and subsequently. They need to be designed carefully to withstand static and dynamic loads to be experienced during their lifetime. This talk will outline some recent results from my group towards understanding the mechanics of lattice structures. New results on equivalent elastic properties, buckling and wave propagation will be discussed.
