What the Cell Sees: Modelling the Bionano Interface
Bionano interactions sit at the heart of some of the most promising technologies of the coming decade, including targeted drug delivery, mRNA vaccines, biosensors, theranostic agents, and engineered interfaces for regenerative medicine. They are, at the same time, the key to understanding the toxicity of nanomaterials. In both roles, what matters is not the pristine nanomaterial but the dynamic corona of proteins and lipids that reshapes its surface on contact with a biological fluid and ultimately determines the fate of the particle and its. This corona governs how the particle is recognised by cell membranes and receptors, directing uptake, intracellular trafficking, and downstream biological response.
In this presentation I will show how computational materials models and nanoinformatics methods allow us to zoom into the bionano interface and identify the principal factors controlling corona formation and the behaviour of nanomaterials in biological media. The multiscale character of the problem demands a combination of physics-based simulation and data-driven models built on machine learning. I will argue that soft matter physics provides the mechanistic backbone that both next-generation nanotechnologies and regulatory science increasingly need.

From Device Physics to Utility-Scale Systems: The Remarkable Reach of Photovoltaics
The global deployment of photovoltaic (PV) technology has accelerated dramatically over the past decade, establishing solar energy as one of the fastest-growing sources of electricity worldwide. South Africa has mirrored this trend, driven by both utility-scale developments and widespread adoption across the commercial, industrial and residential sectors. By early 2026, the country's cumulative installed PV capacity is estimated to exceed 10 GW, highlighting the increasingly important role of PV in ensuring energy security, economic development and the transition to a low-carbon energy future.
Understanding the fundamental physics of solar cells and PV modules remains essential for interpreting the performance of PV systems across all scales. The electronic and optical properties of semiconductor materials determine device efficiency, while module design, environmental exposure and operating conditions influence long-term performance, reliability and degradation. The physical principles that govern charge generation and transport in a solar cell also underpin the analysis of module failures, system losses and the energy yield of large-scale PV power plants.
This presentation traces a personal and scientific journey through the PV value chain, illustrating how knowledge developed at one scale shapes understanding at the next. Beginning with semiconductor crystal growth and materials characterisation of InGaAs and related compounds, the discussion progresses through solar-cell device physics, advanced characterisation techniques, module performance and reliability, and ultimately to the modelling, monitoring and analysis of multi-megawatt PV installations.
By connecting concepts across the scales, the presentation highlights the interdisciplinary nature of PV and demonstrates how a strong foundation in materials science and device physics enables meaningful contributions to the design, operation and optimisation of PV systems. The remarkable reach of PV lies not only in their global deployment, but also in the seamless integration of fundamental science, engineering innovation and societal impact that characterises this rapidly evolving field.

Room Temperature Quantum Mechanics Peculiarities in Nanoscale Systems & their potential technological applications towards SDGs
The intrinsic surface and interface properties of nanoscale systems are correlated to their surface to volume ratio, surface atomic coordination, electron and phonon confinement, and other factors. Such shape & size dependent features are established to give a birth to peculiar quantum mechanics responses. Among such, one could mention; (i) the Fermi Total reflection of cold neutron wave-packet & their trapping within the picosecond time regime, (ii) the Anderson Infrared light localization in semidisordered Carbon Nanotubes & lasing in semi-disordered nanomaterials, (iii) the size dependent bandgap tunability in Mott transition Semiconductor- Metallic phase transition systems, (iv) the relativistic Dirac “S” orbitals contraction & room temperature solid mercury, and last but not least (v) the enhanced thermal conductivity of nanofluids conceptualized by the Father of electromagnetism, James Clerk Maxwell.
This contribution reports on the theoretical & experimental observations of the above-mentioned unusual quantum mechanics governed peculiar phenomena. Likewise, their potential technological applications will be highlighted.

Physics Without Boundaries: Reimagining Physics Through Research, Education and Leadership in the Fourth Industrial Revolution
What does a physicist look like in the Fourth Industrial Revolution? While advances in computational modelling, artificial intelligence, advanced materials, sensing technologies, and data-driven discovery are transforming the discipline, the future of physics will be determined not only by technological innovation but also by our ability to connect research, education, industry, and society while building an inclusive and sustainable community of physicists.
This plenary explores how physics can transcend traditional disciplinary boundaries through examples drawn from computational materials research for Low Earth Orbit, physics education innovation, and industry-linked student projects investigating cricket ball dynamics and acoustic monitoring systems. Together, these illustrate how authentic, interdisciplinary experiences prepare students for the evolving landscape of the Fourth Industrial Revolution while demonstrating the versatility and societal relevance of physics.
Beyond research, the talk reflects on the importance of intentionally creating spaces where people can encounter physics, develop confidence and build professional networks. Through participation in Women in Physics in South Africa (WiPiSA) networking initiatives, contribution to the WiPiSA 20th Anniversary Roundtable, public engagement through radio discussions, and the development of the Meet a Physicist High Tea for female high school learners, I explore how conversations, mentorship, visibility and collaboration can broaden participation in physics and strengthen the
discipline for future generations.
Rather than viewing research, teaching, outreach and leadership as separate responsibilities, I argue that they are interconnected components of a single ecosystem. Building a sustainable and inclusive future for physics requires not only scientific excellence, but also intentional mentorship, collaboration and the creation of opportunities for others to contribute. Ultimately, the physicist of the future will be defined not only by the knowledge they generate, but by the communities they cultivate and the pathways they create for those who follow.

Structured Light and Darkness in Nanophotonics
The rapid development of optical technologies, including optical manipulation and trapping, data processing, sensing and metrology, advanced imaging and microscopy, as well as classical and quantum communications, necessitates the exploration of new degrees of freedom for structuring light in space and time beyond conventional control of amplitude, phase, and polarization. Topological particle-like objects in structured optical fields have emerged as promising candidates for such degrees of freedom. In particular, these optical topologies offer new capabilities for communication, imaging, and sensing through atmospheric turbulence, where refractive index fluctuations distort phase, polarization, and field structure. In this talk, we discuss structured light and darkness, including optical beams with an orbital angular momentum, knotted singularities, and optical skyrmions, and demonstrate their generation, propagation, and interactions with matter in linear and nonlinear regimes. Using metasurfaces and metamaterials, we achieve subwavelength control of optical fields and topology imprinting at fundamental and harmonic frequencies, and introduce spatiotemporal approaches for structuring light jointly in space and time.

Advances in Nuclear Structure Physics
The past two decades have witnessed a resurgence in nuclear structure physics due to the advent of radioactive beam facilities around the world. In parallel, there have been tremendous strides in nuclear structure theory that are able to provide highly accurate predictions from first-principle approaches. New phenomena are being discovered and old paradigms challenged resulting in a much deeper understanding of the interplay of single-particle and collective excitations. In this presentation, I will give an overview of some of the new experimental facilities and their capabilities and examples of structural phenomena that have been revealed over the past two decades. I will also give examples of where nuclear structure impacts tests of fundamental symmetries and searches for physics beyond the Standard Model.

Nanopore Single-Molecule Biophysics
My group has been at the nexus of developing nanopore sequencing of DNA and establishing nanopores as a new tool for single-molecule biophysics. Much of our work is based on the engineered protein nanopores through which we pull DNA. Here, I will show the stunning capabilities of using this nanopore technology to observe biology’s molecular machines in real-time as these enzymes move along DNA or RNA. We easily achieve ten times better position and time resolution than optical tweezers, while simultaneously measuring the exact nucleotide sequence within the enzymes. I will show hereto unseen detail of the motion of helicases, DNA and RNA polymerases, reverse transcriptases, etc. Besides establishing decisive kinetic enzyme models, our method reveals many surprisingly properties of these enzymes.
Throughout the talk, I will highlight the power of physicists’ approaches to interdisciplinary research and technology.

Astronomy for a Better World: Connecting Knowledge, Society, and Sustainable Development
Traditional development approaches are increasingly struggling to respond to the complexity and urgency of contemporary global challenges, including widening inequality, climate instability, and the demand for inclusive and sustainable growth. Many existing development frameworks remain siloed, with limited integration of science, technology, and innovation, constraining their overall impact.
At the same time, scientific disciplines such as astronomy are often perceived as primarily academic, focused on advancing fundamental knowledge with limited direct societal application. This perception obscures the significant role that science has played in driving technological innovation and human capital development. In particular, technologies originating from astronomical research have contributed to advancements in digital imaging, medical diagnostics, satellite communications, and large-scale data processing, demonstrating the far-reaching impact of science on modern society.
The International Astronomical Union Office of Astronomy for Development was established in 2011 to address this gap by leveraging astronomy, within the broader context of science, as a tool for sustainable development. Operating across more than 100 countries, the OAD has supported hundreds of projects that illustrate how science can contribute to education, scientific capacity building, technological innovation, cultural preservation, environmental awareness, and social cohesion.
This talk will present an overview of the OAD’s strategic framework, flagship ecosystem, and global network model, highlighting its alignment with the United Nations Sustainable Development Goals. Through competitive Calls for Proposals and strategic partnerships, the OAD enables locally driven initiatives that apply science, particularly astronomy, to community-defined challenges, including STEM education, mental wellbeing, Indigenous knowledge systems, astrotourism, and science diplomacy.
Beyond programme implementation, the OAD’s growing body of global practice has created important opportunities for research. Evidence generated through projects, partnerships, and regional networks is increasingly informing questions around impact evaluation, science engagement, capacity development, innovation ecosystems, and the role of scientific knowledge in society. This has contributed to the emergence of astronomy for development - and more broadly science for development - as a developing interdisciplinary research field that connects the physical sciences with development studies, policy, education, and social science methodologies.
By positioning science - and astronomy as a powerful exemplar - within the broader development landscape, this work demonstrates its potential as a cross-cutting, interdisciplinary tool capable of contributing meaningfully to sustainable and inclusive development.

The Sun in Focus: From Early Telescopes to High-Resolution Physics
From its earliest presence in southern African cosmology, where the Sun was revered in San and Nguni traditions as a life-giving and regulating force, to its formal study within the Royal Astronomical Society era of systematic observation, our understanding of the Sun has evolved through a remarkable fusion of culture, geography, and technology. This plenary traces the evolution of solar observation from early sunspot sketches to modern diffraction-limited imaging with the Swedish 1-m Solar Telescope and more recently with the Daniel K Inouye 4-m Solar Telescope. These advances have transformed the Sun from a distant luminous disk into a dynamic, multi-layered plasma system, where fine-scale magnetic structuring and energy transport processes are now resolved across multiple spectral domains. The talk highlights how increasing spatial, temporal, and spectral resolution, combined with global collaborations involving institutions such as the South African Astronomical Observatory, has deepened our understanding of the coupled photosphere–chromosphere–corona system and its role in space weather. By bridging heritage, international collaboration, and cutting-edge technology, we move closer to unlocking the fundamental plasma physics governing our nearest star.
