5 lectures in 25 hours – new record

Uncategorised Posted by Gunnar CedersundPosted on Sun, October 26, 2025 23:00:51

There is a big demand to hear about our digital twins these days. Almost every week, we have been invited to give a lecture in some event, somewhere in the world. And some weeks more than one. In fact, last week, a new record was reached: 5 presentations in 25h! Here is a short description of the five presentations:

1 – Oct 14, 13.15-13.45: Joint presentation with Johan Holmsäter at Holistal’s event Health HUB. This was together with some of the most prominent health leaders in Sweden. Johan Holmsäter started the 500 000 people strong health organization Friskis & Svettis, and is arguably the single person that has made the biggest impact for the health and healthy habits in Sweden. Other important presenters were Birgitta Thörn (CEO of Holistal, and founder of e.g. the gym & health chain Itrim), Göran Adlén (the “aging backwards” guy, and a great lecturer), Anders Rosengren (a Swedish MD with lots of interesting ideas about the mentality of health, and the founder of the successful online tool Livsstilsverktyget), etc. You can read more about the event here, and at these two previous blog posts: post by me, post by Katja.

From the final panel debate. You see Johan Holmsäter to the right in an armchair, Göran Adlén to the left on stage, and Anders Rosengren to the right, also on stage.

2 – Oct 15, 10-12: General rehersal at Norlandia, in the DN house, for the big launch event of our digital twin app, to be held the week after. I had a presentation of ~25 min prepared, where I present how our multi-level and multi-organ digital twin for individuals will enter into an eHealth app, that will be given to all 3000 employees at Norlandia. More about the actual launch event (which was held on Oct 23), will come in a separate blog post.

3 – Oct 15, 12.50-13.20: Pod cast with Cambio, at the big Cambio Connect event. This podcast was broadcasted live for all attendees in the event, over lunch, and will also be sent out later in the autumn to around 1500 health care personnel.

4 – Oct 15, 13.35-13.55 Presentation at the final workshop of MeDigit, a VINNOVA financed project on medical digital twins. I held this presentation online, from a corner in one of the corridors. The minute I was finished, some staff came up to me, and said that I had to “mic up” for the next presentation 🙂

5 – Oct 15, 14.20-14.35 Presentation and panel debate at the big stage at the Cambio Connect event. This was part of the last session, on AI, and wrapped up my crazy 25 hours of presentations, presentations, presentations! After this, it was time to relax a bit, and chill out a few hours at my hotel, before travelling home to Linköping again.

Picture of me at the dinner on Oct 14, in the evening. I didn’t have a lecture then, but this picture gives a feeling for the scale of the event, and the size of the big stage: it probably featured 500+ participants.



Health Hub – Make Sweden number one healthy country in Europe

Events, News Posted by Katja WoxellPosted on Sat, October 25, 2025 21:19:38

Health Hub – a room full of visionaries on a mission: Make Sweden number one healthy country in Europe.

  • AI twins that show you what your health will look like in 20 years with your current lifestyle and inspire you to make change now – presented by Gunnar Cedersund and Johan Holmsäter.
  • How you frame your experience may be your number one ticket to better health: Rather than focusing on “I’m reducing these unhelpful habits” focus on “I’m magnifying these helpful and enjoyable habits”.
  • Every single movement during the day counts.
  • Daily movement, rest, diet, sleep: Four pillars of good health. All four connected. None of them can be compromised.
  • Employee health should be a vital business goal, not a good-to-have or a temporary effort.
  • It is never too late to become healthy.

While popular trends in health come and go, one thing is alarming: We have never had so much information about health and yet we have never been so unhealthy. We have well-tested theories. What we need are applied, pragmatic solutions to health problems we are facing. We must start thinking in terms of preventive healthcare. This was the conclusion. Everyone left them room with an intention to carry the torch for making preventive healthcare a reality.

Gunnar Cedersund and Johan Holmsäter, standing in front of the audience, are presenting how medical digital twins can be (and is being) used for preventive healthcare.

Presentations in Stockholm next week – Health HUB, with Johan Holmsäter

Events, Uncategorised Posted by Gunnar CedersundPosted on Sat, October 11, 2025 19:25:58

Next week, I will be in Stockholm to give presentations at some different events. First out is Health HUB, arranged by HOLISTAL, and focusing on preventive health. I am giving this presentation together with the health guru Johan Holmsäter, who – among many other things – founded Friskis & Svettis (half a million members!), back in the early 1980s. Since then, he has done many things, and one of them is corporate health. In this, he has many examples of turning around high rates of sick leave (e.g. 8% to 2%) by utilizing some of his various health programs. In the last 1-2 years, Johan, our spinoff company SUND, and a few others have jointly founded a new company – Lev Skönare – which now are rolling out a joint product: his health programs empowered by our digital twins. In this joint presentation, you will hear about both of our personal and professional journeys, as well as about the health journey “Hälsoresan”, which our customer Norlandia is about to embark upon next week.

Later in the week, on Wednesday, I will give a presentation at the event Cambio Connect. More info about that in a separate video and blog post, to be posted shortly.

New Funding Secured for a Digital Twin-Based eHealth Application

Uncategorised Posted by ISB GroupPosted on Thu, July 04, 2024 10:37:11

We are excited to announce that we have secured new funding from ALF, the state-funded research program for clinical research in collaboration with Swedish regions. The grant has been awarded to Gunnar Cedersund, the coordinator of STRATIF-AI, for a project titled “Implementation and Evaluation of a Digital Twin-Based eHealth Application for Preventive Health Dialogues.”

This project is directly linked to Clinical Study 2 within STRATIF-AI, which assesses our application designed for use during and after preventive health dialogues at primary healthcare centers. In this study, we will compare standard clinical practice with 300 health dialogues incorporating the new app.

With this additional funding, we can enhance app development and expand the clinical study to include 400 patients. The project will span three years, with an annual budget of 900,000 SEK, totaling approximately 3 million SEK (around 300,000 EUR). This support will significantly bolster our efforts in the field of preventive healthcare.



Workshop: New hybrid approaches to Precision Medicine: machine learning, generative AI, and digital twins

Uncategorised Posted by ISB GroupPosted on Fri, June 28, 2024 13:52:51

In this workshop, which will be held the 5th of November, we will discuss hybrid approaches, combining traditional bioinformatics and machine learning, with new generative AI approaches and mechanistically based digital twins. This combination of methods is ideal for dealing with a variety of different data types, and for developing AI models that are explainable and trustworthy. The event will feature keynote lectures, talks selected from abstracts, a poster session, and will be in hybrid format. Link to more info here:

STRATIF-AI meeting with other EU projects

Uncategorised Posted by ISB GroupPosted on Wed, June 26, 2024 10:59:16

A few weeks ago, on June 10, STRATIF-AI had its first meeting with fellow EU projects funded under the same call, all focusing on the use of AI for improved patient stratification. This initial two-hour meeting served as an introduction to each project and a discussion of key shared challenges (see Figure below). These challenges include data interoperability, federated learning, trustworthy and explainable AI (xAI), and MDR certifications.

During the meeting, we presented some core concepts of STRATIF-AI, such as our hybrid approach that combines multi-level, multi-timescale, and multi-organ simulations using mechanistic models as inputs to machine-learning models. This hybrid approach enhances the explainability of our models.

Furthermore, we explained shortly how STRATIF-AI uses data harmonization in two places: i) in connection to the federated learning set up by a collaboration between Catalina Martinez Costa (University of Murcia) and Lucia Gregorio Rodriguez (TREE), and ii) in connection to integrating a copy data from a variety of different sources into a personal data vault (Jesper Fellenius at Z2). 

This collaboration and network of related projects will be useful for us to use in various related topics as we move forward, and we from STRATIF-AI are looking forward to new meetings. Thanks to the team at PREPARE for setting this meeting up.



A Recap of the Latest STRATIF-AI Meeting

Uncategorised Posted by ISB GroupPosted on Thu, May 16, 2024 18:13:12

On April 11-12, we had a new bi-yearly meeting in STRATIF-AI. This meeting was held in beautiful Nottwil, Switzerland, where the Swiss Paraplegic Research center (SPF) is situated.  SPF is responsible for the work with policy and actions toward stakeholders to achieve ultimate clinical implementation, and they were also the hosts of this event.

We have these events every 6 months, and they serve both the purpose of team building and increased understanding of each others’ perspectives and serve to help us focus on the most urgent and timely topics. This time we focused primarily on the design of the 6 clinical studies, which ethical applications were to be submitted at the end of that month. Four of these studies are dedicated to the collection of patient data, aimed at training both the machine learning algorithms and the mechanistic aspects of digital twins. The remaining two studies focus on the real-world testing of eHealth apps within clinical settings. The largest of those will test whether the digital twin improves clinical health conversations, in 300 patients, compared with 300 matched controls.

Overall, the meeting was a success, and we have now passed the planning phase of the project, with requirement specifications and ethical plans, and are now moving into action: into prototype development of the apps, and towards the first pilot studies.
