Speaker: ​Guglielmo Lockhart (University of Bonn).​Abstract: General principles suggest that the spectrum of excitations of quantum gravity theories includes not just pointlike particles, but also higher-dimensional membranes. In this talk I will focus on a specific class of one-dimensional membranes, the faithful strings, whose properties can be described using the language of vertex operator algebras. I will discuss how this mathematical structure encodes symmetries of quantum gravity theories, and makes it possible to determine refined information like gauge group topology. Moreover, I will show that modular invariance of the faithful string torus partition function is a powerful tool to detect inconsistencies in a candidate quantum gravity theory, or conversely to identify apparently consistent quantum gravities and study their properties. This provides an exciting opportunity to study exotic quantum gravity models that do not admit any known weakly coupled realization within string theory, in supersymmetric as well as non-supersymmetric settings.

About the lectureThe role of predation in the microbial world is like that in the macroscopic world: it makes energy flow to form food webs, regulates prey population, and is a source of biodiversity. However, mechanistically, predation operates very differently since in the microbial world viscosity impedes predator-prey contact, there is no vision to facilitate prey (and predator) perception, and observed behaviours are often counterintuitive. I will demonstrate how planktonic predators, from few micron-sized nanoflagellates to mm-sized copepods, have overcome the impeding effect of viscosity by a fascinating diversity of adaptations, and how microbial predators have balanced the fundamental problem of eating without themselves being eaten. I will show how this trade-off has driven an evolutionary arms race between diatoms and copepods with important consequences for the biological carbon pump. Finally, I will describe how the functional diversity of foraging in flagellates provides a new lens through which to explore early eukaryotic evolution. The presentation will be light on physics and rich in videos and animations.About the speakerThomas Kiørboe is a professor of Biological Oceanography at DTU Aqua.

Speaker: Ben Brown (​IBM).Abstract:In seminal work (arXiv:quant-ph/9707021) Alexei Kitaev proposed topological quantum computing (arXiv:cond-mat/0010440, arXiv:quant-ph/9707021, arXiv:quant-ph/0001108, arXiv:0707.1889), whereby logic gates of a quantum computer are conducted by creating, braiding and fusing anyonic particles on a two-dimensional plane. Furthermore, he showed the proposal is inherently robust to local perturbations (arXiv:cond-mat/0010440, arXiv:quant-ph/9707021, arXiv:1001.0344, arXiv:1001.4363) when anyons are created as quasiparticle excitations of a topologically ordered lattice model prepared at zero temperature. Over the decades following this proposal there have been considerable technological developments towards the construction of a fault-tolerant quantum computer. Rather than maintaining some target ground state at zero temperature, a modern approach is to actively correct the errors a target state experiences, where we use noisy quantum circuit elements to identify and subsequently correct for deviations from the ideal state. We present an error-correction scheme that enables us to carry out robust universal quantum computation by braiding anyons. We show that our scheme can be carried out on a suitably large device with an arbitrarily small failure rate assuming circuit elements are below some threshold level of local noise. The error-corrected scheme we have developed therefore enables us to carry out fault-tolerant topological quantum computation using modern quantum hardware that is now under development.

Shomrik Bhattacharya defends his PhD thesis at a public lecture: “The Fundamental Group of the Complement of the Wobbly Divisor in the Intersection of Two Quadrics”.The chairman of the assessment committee, Associate Professor Fabian Haiden, will act as chairman at the defence.The PhD defence takes place in IMADA Conference Room (Ø18-509-2).All are welcome.

About the lecture:Humans have introduced a huge array of novel chemical and material pollutants into the Earth system, and continue to do so at an ever-increasing scale.  Humanity’s pollution disrupts Earth system processes, and the stream of novel pollutants flowing into Earth’s environment poses a constant threat of new planetary-scale impacts.  This lecture provides a summary of nearly 15 years of evolution of ideas about how to confront risks and threats from planetary-scale pollution on Earth, and about a new initiative to extend those principles to protection of the moon, Mars and other celestial bodies where humans explore, visit, and may eventually colonize.About Matthew MacLeodMatthew MacLeod is Professor of Environmental Science at Stockholm University, Sweden, and Deputy Dean of Earth and Environmental Science.  He is a Fellow of the Royal Society of Chemistry (FRSC) and is currently Sweden’s “Designated Expert” on Persistent Organic Pollutants for the Arctic Council’s Arctic Monitoring and Assessment Programme (AMAP). He holds a Bachelor’s degree from the University of Victoria (Canada), and Master’s and PHD degrees from Trent University (Canada). Prior to moving to Sweden in 2010 he was a post-doctoral researcher at the Lawrence Berkeley National Laboratory (USA) (2002-04) and a Research Group Leader at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland (2004-10). Professor MacLeod uses mathematical models and data analysis to study the factors that control human and environmental exposure to environmental contaminants, and the links between the three dimensions of the “triple planetary crisis” of pollution, climate change and biodiversity loss. The goal of his research is to build a quantitative understanding of humanity’s impacts on the Earth system, and to develop practical tools and guidance to support rational decision-making.The event is organized by DIAS Chair Zhanyun Wang

About the lectureAging is often presented as one of the greatest scientific challenges of our time. Yet understanding why some individuals remain healthy well into old age while others develop disease requires insights from many disciplines, including genetics, epidemiology, medicine, statistics, demography, and the social sciences.In this lecture, Sara Hägg will explore how modern aging research has evolved from gerontology and geriatrics to understanding the biological processes that drive healthy aging. Drawing on examples from large population studies and molecular aging research, she will discuss how biological age can be measured, what these measures can and cannot tell us, and how they are shaping current efforts to improve healthspan.The lecture will also reflect on the opportunities and challenges of interdisciplinary research, highlighting how scientific breakthroughs often emerge at the intersection of fields and why collaboration is essential for addressing complex questions about aging, health, and longevity.About the speakerSara Hägg is Associate Professor of Molecular Epidemiology at Karolinska Institutet and an internationally recognized researcher in the biology of human aging. She leads a research group that investigates why people age differently and how genetic, molecular, environmental, and lifestyle factors shape trajectories of health and disease across the lifespan.Her research combines epidemiology, genetics, biostatistics, omics and bioinformatics to identify biomarkers of biological aging and to understand their relationship with age-related diseases, functional decline, and mortality. Using large population-based cohorts and advanced causal inference methods, she studies mechanisms of healthy aging and evaluates potential interventions aimed at extending healthspan rather than simply lifespan.Sara serves as Principal Investigator for several major national and international research projects funded by organizations including the Swedish Research Council and the U.S. National Institute on Aging. Her work has contributed to the development and evaluation of biological age measures that are increasingly used in research and precision medicine.Beyond academia, Sara is a highly sought-after science communicator and public speaker. She frequently appears in newspapers, television, radio, podcasts, and public debates, where she provides evidence-based perspectives on aging, longevity, and preventive health, helping bridge the gap between scientific discovery and public understanding.The event is organized by Moustapha Kassem

The impact of AI-powered clinical assistants on clinical practice and healthcare experiencesAbout the ConferenceArtificial intelligence (AI)-based chatbots, automation tools, and patient-facing robots, powered by large language models (LLMs), are rapidly becoming integral to modern healthcare, both in the Danish healthcare system and globally.Clinicians increasingly use these technologies for information-seeking, documentation through ambient voice systems and digital scribes, clinical decision support, communication, and patient interaction. Patient-facing robots are emerging in hospitals, clinics, and home-care settings to assist with, e.g., rehabilitation, medication adherence, and emotional support. As these assistants begin to complement or replace tasks traditionally performed by humans, they transform both the delivery of care and the experience of providing and receiving it.National and international research projects are emerging, exploring these transformations, and new interdisciplinary networks are forming.The purpose of this conference is to bring together researchers and clinicians for knowledge-exchange, constructive dialogue and networking.Date12th of November 2026 - 10:00 to 17:30 followed by a conference reception.VenueUniversity of Southern Denmark, Odense Campus, DIAS auditorium.The conference is hosted and co-funded by the Danish Institute of Advanced Studies (DIAS), University of Southern Denmark (Research Unit of General Practice and Department of Business and Management) and Odense University Hospital.The cross-disciplinary research network Caring for People and Technologies at the University of Southern Denmark organizes the conference (Associate Professor Elisabeth Assing Hvidt, Professor Dorthe Brogård Kristensen, Assistant Professor Line Maria Simonsen, Post Doc Kathrine Rayce, Associate Professor Elena Shulzhenko and special consultant Henriette List).
