About the project
Objective
The project aims to establish the technical, organizational, and legal foundations for an AI-based feedback system that supports operators at Stockholm City’s Elderly Safety Call Center. The system will function as a co-pilot, offering insights, alerts, and structured performance feedback to strengthen decision-making and professional development. Central objectives include analyzing operators’ decision-making processes and operational challenges in high-stakes, time-critical situations.
Another key objective is to identify the legal, ethical, and technical boundaries for data exchange across municipal and regional healthcare infrastructures. These insights will guide the design and prototyping of the LLM-based feedback system that enables post-call analysis and continuous learning. Further on, the project outcomes will inform the future development of a real-time feedback system.
Background
Elderly safety call centers play a critical role in Sweden’s elderly care system. Operators handle acute welfare and emergency-related calls, coordinate between medical and elderly home care actors, and make rapid decisions regarding additional services or short-term interventions. As the service operates during evenings, nights, and weekends, when regular elderly care services have limited staffing, operators manage cases under greater uncertainty and time pressure. The work is carried out under significant pressure, guided by a multitude of rules, guidelines, and policies, yet operators receive little structured feedback on the quality or outcomes of their decisions.
At the same time, demographic developments increase the need for efficient decision-making. A rising need of elderly care is projected to grow substantially and will lead to increased staffing requirements in elderly care. Managing this development without compromising quality will require new forms of digital support, particularly for staff working in high-stakes and time-critical environments such as night and weekend operations.
Current CRM systems in elderly care call centers provide access to information but offer limited decision support, structured learning, or follow-up of outcomes. Facing a stressful decision-making processes with little support affects both staff well-being and the quality of services provided to older adults. Strengthening decision support has the potential to reduce errors, improve consistency, and enhance both staff and patient well-being, while also generating significant savings in public resources.
Against this backdrop, AI-powered feedback systems offer a promising avenue. Recent advances in large language models (LLMs) and data-driven communication analysis open new possibilities for post-call learning, performance feedback, and more systematic follow-up of decision outcomes. This project aims to address these challenges by developing an AI-based feedback system that supports operators in elderly safety call centers. By enabling structured post-call analysis, reflective learning, and improved decision-making, the project seeks to enhance operator support, strengthen the resilience of elderly care services, and contribute to a sustainable response to the demographic challenges ahead.

About the project
Objective
The overall objective of this project is to develop a predictive model for the progression of Aortic Valve Stenosis (AVS) by integrating repeated CT imaging, fluid–structure interaction (FSI) simulations, and deep machine learning techniques. Through comprehensive analysis of large-scale clinical datasets and high-fidelity simulations, this project seeks to move beyond conventional imaging and hemodynamic metrics to enable early detection, individualized prognosis, and improved clinical decision-making in AVS management.
Background
Aortic valve stenosis (AVS) is dangerous because it leads to obstructed blood flow from the heart, causing increased pressure within the heart and raising the risk of heart failure, arrhythmias, and other severe complications. Over 2 million people worldwide are affected by the condition, with its prevalence increasing as the population ages, and it is often diagnosed through imaging techniques such as echocardiography and CT scans. Treatment options include surgical and transcatheter aortic valve replacement (SAVR/TAVR), both aiming to relieve symptoms and improve heart function, though there is uncertainty in selecting the best approach for individual patients based on their health condition and the severity of the disease.
Therefore, there is a critical need for a physics-based understanding of the progression of AVS, as current recommendations of AVS management and monitoring do not fully account for the complex interaction of hemodynamics (blood flow) and biomechanics (tissue deformation), which drive valve degeneration and calcification. In particular, oscillatory shear index and high shear stress in certain regions of the valve and aorta, along with altered cyclic loading, contribute to the pathological changes in the valve, exacerbating stenosis and complicating treatment outcomes.
Cross-disciplinary collaboration
This project brings together a new cross-disciplinary and complementary collaboration uniting experts in cardiovascular imaging, fluid dynamics, and machine learning to advance predictive modeling of aortic valve disease:

- Payam Esfahani, is a postdoctoral researcher at KI in Magnus Bäck’s research group. Research focus on using advanced AI/ML applied to biomedical imaging and will remain a key contributor to the development of the project’s methodologies.
About the project
Objective
The CARE-AI (Causal Adaptive Reasoning for Effective Hospital Admission Interventions) project aims to fundamentally change how hospitals prevent patient readmissions. Today’s AI systems can predict which patients are at high risk of readmission. However, they cannot tell doctors what to do to stop it.
This project moves beyond simple prediction to intervention optimization. We are developing a framework using ‘causal AI,’ a method that identifies cause-and-effect relationships, to answer the most important question: ‘Which specific intervention will most benefit this specific patient to avoid readmission?’ Rather than only marking a patient as high-risk, the CARE-AI system will guide clinicians in choosing the best, personalized steps. This could mean adjusting medication, setting up a follow-up appointment, or offering education tailored to the patient.
The two-year project has two main phases. In the first phase, we will develop the core causal AI algorithms—AI methods that determine which actions cause better outcomes for which group of patients—using comprehensive, anonymized health data from Region Stockholm’s electronic health records (EHR) and the VAL databases (VAL is a regional healthcare data). In the second phase, we will conduct a Randomized Controlled Trial (RCT) at Södersjukhuset. In this trial, 250-300 high-risk patients will be randomized to receive either standard care or personalized interventions guided by the new causal AI framework.
The ultimate goal of the project is a clinically validated AI tool that provides clear, interpretable recommendations to healthcare staff, leading to fewer readmissions, better patient outcomes, and more efficient use of healthcare resources.
Background
Hospital readmissions are a critical and costly challenge for healthcare systems worldwide. In Sweden, 15.2% of all patients are readmitted to the hospital within 30 days. This figure rises to an alarming 28% for elderly patients with multiple chronic conditions.
The core problem is that many of these readmissions are preventable. The “one-size-fits-all” approach to discharge and follow-up isn’t effective. Current predictive AI models fall short because they are based on correlation, not causation. They can identify that a patient looks like other patients who were readmitted. But they can’t determine why or identify the specific, modifiable factor that would change the outcome for that individual.
This project tackles that fundamental gap. We’re moving from asking “Who is likely to be readmitted?” to “Who is likely to benefit from which intervention to avoid readmission?” By identifying the causal drivers of readmission, we can target interventions that make a real difference. With each hospital bed costing approximately 12,000 SEK per day, preventing unnecessary readmissions is crucial for a sustainable healthcare system.
Cross-disciplinary collaboration
The CARE-AI project is built on a “triple-helix” collaboration. This approach brings together world-class expertise from academia, clinical healthcare, and industry. This structure is essential to ensure the project is not only scientifically rigorous but also clinically relevant and practically implementable.
- KTH Royal Institute of Technology (Academia): Karl Henrik Johansson, Prof., and Umar Niazi, researcher, provide the project’s methodological leadership. They will develop novel causal AI, machine learning, and reinforcement learning algorithms. These algorithms form the core of the CARE-AI framework.
- Karolinska Institutet / Södersjukhuset (Healthcare): Patrik Lyngå, Assoc. Prof., and Raffaele Scorza, M.D. and Ph.D., provide crucial clinical expertise and validation. They are responsible for designing and executing the RCT. This ensures the AI’s recommendations are medically sound, safe, and effective in a real-world hospital environment.
- Sirona Group (Industry): Jenny Censin, M.D. and Ph.D., provides deep implementation expertise and a pathway to real-world deployment. Sirona brings experience in healthcare data analytics and existing platforms like AINA. This will be key to integrating the new AI framework into current clinical workflows and health data systems.
This close collaboration ensures a constant feedback loop. Clinical needs from Södersjukhuset and implementation challenges from Sirona directly inform the AI development at KTH. At the same time, the new AI tools are immediately tested and refined in a clinical setting.
About the project
Objective
This project aims to advance, evaluate and demonstrate three interactive sonic prototypes designed to support sleep across three critical stages: sleep onset, the sleep period, and awakening. The SoundAsleep app recommends sleep soundscapes based on the user mood; the Sonic Blankets are interactive sonic textiles designed to support sleep through soothing auditory and tactile stimulation; and the SoundRise alarm fosters a gentle and natural awakening experience by emitting a gradually rising sound starting below the ambient room tone. Prototypes will be advanced through contextual adaptation, enhancing their personalisation and sonic versatility, and participatory design, engaging varied age groups and genders.
Background
Sleep disturbances are common conditions that impact both physical and mental health; yet few technologies exist to support sleep quality. Cultural and historical practices highlight sound’s therapeutic potential. In addition to singing and music, broadband noise, natural soundscapes, and specific tones are gaining popularity. But designing sound alone is insufficient. Interventions need to consider demographic and contextual factors, such as age, gender, and the physical environment, which substantially affect sleep quality. In recent years, sleep technologies have started to compete with traditional sleep interventions, yet many interventions remain under-evaluated.
This research aims to contribute to the development of non-pharmacological, low-risk, personalised and adaptive sleep interventions, while simultaneously enhancing public awareness of the role of sleep in health and wellbeing.

About the project
Objective
Breast and prostate cancers are among the most diagnosed cancers worldwide and in Sweden, arising from a complex interplay of genetic, environmental, and epigenetic factors. This project aims to develop an AI-powered, open-source, explainable toolkit that provides clinicians with a holistic and personalized assessment of breast and prostate cancer risk. By leveraging Swedish national health registries, we will capture key risk dimensions and integrate them into advanced predictive models capable of handling complex, interacting factors.
Specifically, the project will design and validate advanced predictive models to quantify the combined and individual contributions of multiple risk factors; implement a user-friendly, open-source Python toolkit that translates complex model outputs into actionable clinical risk scores and visualizations for decision support; conduct a clinical pilot in a regional setting to evaluate usability, functionality, and preliminary clinical utility in identifying individuals at elevated risk; and finally, formulate a strategy for national scaling and holistic integration, including a roadmap for incorporating genetic risk profiles from parallel projects, thereby paving the way for a comprehensive cancer risk assessment platform.
Background
Although high-risk inherited mutations (such as in BRCA1/2) are well known, they only explain a fraction of breast and prostate cancer cases. A large share of risk is instead driven by modifiable lifestyle factors acting through epigenetic mechanisms over the life course. Current clinical practice and many existing risk models still treat these factors in isolation and struggle to capture their cumulative, non-linear, and interacting effects. At the same time, Sweden maintains exceptionally rich national registries covering cancer diagnoses, healthcare utilization, prescriptions, demographic and socioeconomic data, and environmental conditions.
These data sources are ideal for characterizing the totality of non-genetic exposures but remain underused in integrated, clinically oriented tools. Traditional statistical methods often cannot cope with the high dimensionality and complexity of such data, while state-of-the-art AI and machine-learning approaches tend to function as “black boxes” that clinicians may be reluctant to trust in high-stakes decisions. This situation creates a clear gap for explainable, registry-driven AI that can bridge genetic and non-genetic risk into a transparent and usable decision-support tool.

About the project
Objective
Kidney diseases affects approximately 10% of the world’s population and is projected to become one of highest cause of life-lost-years within two decades. Despite this growing healthcare threat, diagnostic methods remain insufficiently precise, which unfortunately hinders early quantitative kidney disease staging. We aim to demonstrate a precision medicine pipeline that combines high-resolution optical 3D whole biopsy imaging with advanced AI-assisted 3D image analysis. Our approach eliminates preparation-induced biases by not slicing tissue biopsies, thereby preserving native 3D architecture and in-context spatial relationships. High-resolution imaging in 3D will spatially resolve key structural and molecular disease markers across scales in optically cleared biopsies. Moreover, our pipeline will automate 3D disease staging using AI-based image analysis, employing cutting-edge self-supervised learning to extract, segment, and quantify disease-relevant features objectively.
Background
Pathology impacts all aspects of patient’s care from identifying a disease, to monitoring its progression and to make crucial treatment decisions. Clinical kidney pathology thus plays a central role as method for diagnostic support in healthcare to help renal physicians and patients. Present nanoscale kidney pathology analysis is done in ultra-thin biopsies by electron microscopy, losing precious in-context 3D information of morphological and molecular pathophysiology. Moreover, used workflows are highly labor intense across sample preparation, imaging and imaging analyzing steps.
Cross-disciplinary collaboration
Imaging and image analysis are inherent pathology tools that can deliver diagnostic support and guide patient care. Our developed kidney pathology workflow will be faster, more precise, save healthcare labor costs, and be less biased with automate AI analysis support. The exploration of self-supervised methods for functional structure analysis is furthermore a rapidly growing and impactful area in AI, as researchers seek more sophisticated ways to analyze high-dimensional biological data without manual annotations. Our work positions KTH at the forefront of this cutting-edge field, meeting the rising demand for robust, scalable AI tools that can improve diagnostic accuracy and consistency.

This project is primarily situated at the intersection of Rich and Healthy Life and Cooperate within the Digital Futures research matrix. It explores how AI-enhanced XR environments can foster meaningful human-AI collaboration across immersive scenarios. The project also contributes to the societal context by designing XR experiences that support personal development, creativity, and skill-building. Through dynamic, interactive, and adaptive environments, the system enables users to engage in: (1) self-paced learning and creative prototyping, (2) scenario rehearsal and training, and (3) immersive co-creation. Central to the Cooperate theme is the exploration of multi-agent and multi-user interaction, focusing on how AI agents can support, guide, or adapt in real time to facilitate shared decision-making and effective human-human collaboration, mediated or enhanced by AI.
Background
Artificial Intelligence (AI) and Extended Reality (XR), which includes Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR), represent two rapidly evolving domains that are reshaping the modalities through which humans engage with digital systems. AI technologies are now deeply embedded in a wide array of applications, ranging from algorithmic recommendation systems and automated content generation to complex decision-support tools used in domains such as traffic management and surgical procedures. Concurrently, XR technologies are becoming increasingly mainstream due to advances in hardware and the availability of affordable head-mounted displays, making immersive experiences more accessible to both industry and the general public. Although both AI and XR are subjects of extensive research, the intersection of these fields, particularly within the context of Human-Computer Interaction (HCI), remains relatively under-investigated. In particular, the integration of AI-driven agents, including conversational agents, within XR environments poses novel questions regarding interaction design, user experience, and the role of intelligent systems as co-actors in immersive settings.
