A year of STEM collaboration: What we learned and what comes next
Clear role models, access to relevant networks and visible paths from school to working life can play a major role in whether young people continue developing their interest in STEM. In the district of Järva, that connection has been a central focus throughout 2025.
Schools, universities and local companies have worked together to strengthen the curiosity for technology, mathematics and engineering among young people aged 13–19. The collaboration has combined hands-on activities with opportunities for students to meet professionals in STEM and see what these careers look like in practice.
Alongside the practical work, Kista Science City, KTH, Stockholm University, Vetenskapens Hus and the City of Stockholm also conducted a pre-study mapping existing STEM initiatives in Järva. Through interviews with teachers and students, we gained a clearer view of where the ecosystem is strong and where additional structures are needed to support a more coherent path forward for young people.
Bringing STEM closer to students
During 2025, students in lower secondary school met researchers, engineers, developers and other professionals working in STEM. Among the organisations involved were Stockholm University and its Game lab in Kista, KTH, Vetenskapens Hus, Ericsson, IBM, Kodcentrum, Rejlers, Knightec, My Dream Now, Funki, Rookie Startups, Changers Hub and the Stockholm Science and Innovation School.
More than 400 students participated in activities ranging from workshops to school visits, giving them a chance to see how STEM is used in real settings.
One highlight was Tech Day in Kista, where 120 students from year 7 and 8 explored different aspects of technology and engineering. Afterwards, 50 percent said they could imagine working in a STEM field in the future, an increase of eight percentage points compared with before the event. As one student put it:
“When they showed us the cool things you can do with technology, I got excited. I realised I might be able to work with something like that in the future, which I hadn’t thought about before.”
Insights from 2025
Many initiatives, but limited coordination
The pre-study identified around 15 initiatives in Järva aimed at inspiring young people in STEM. Most of them focused on technology and some on mathematics through homework support. The range is wide, but the activities are not yet connected in a way that gives students a clear, continuous path forward. Schools, academia, civil society and industry all contribute, but stronger coordination is needed to bring these efforts together.
Limited access to role models and networks in Järva
Many young people have limited contact with professionals and established networks within STEM. While interest and ambition are often high, continued engagement depends on whether students meet people working in the fields they are curious about and gain insight into real study and career paths. Teachers highlight that this challenge affects many students, and that the lack of networks and visible role models — particularly women in STEM — shapes how young people imagine their future options.
Schools call for clearer progression and continuity in STEM education
Interviews with teachers and career counsellors highlighted the lack of structured STEM progression for students aged 13–16. Schools are asking for programmes, ideally developed together with industry and academia, that begin as early as year 7 and follow curriculum goals with clear steps forward. When students understand how their learning connects to further studies and career options, their motivation grows.
Looking ahead: building long-term STEM pathways
The insights from 2025 have created a clearer foundation for how schools, industry and academia can work together going forward. In 2026, the collaboration continues with the aim of developing more structured STEM pathways that give students continuity over time.
For companies and universities, this means staying close to the work taking place in schools and contributing with practical perspectives from their fields. Such involvement helps strengthen the link between what students learn in the classroom and the opportunities that exist beyond it.
The long-term ambition is to create conditions where more young people in Järva can pursue their interest in STEM and see possible routes into further studies and future careers.

Understanding online risks: Lisa Kaati’s research at DSV in Kista
Much of today’s public conversation takes place online, where the volume of posts, comments and messages grows every year. For analysts, schools and public authorities, this creates a practical challenge: harmful language, personal attacks and signals of escalating behaviour appear at a pace that makes manual review difficult.
At the Department of Computer and Systems Sciences (DSV) in Kista, researcher Lisa Kaati studies these environments. With a background in computer science and more than a decade at the Swedish Defence Research Agency (FOI), she develops methods that help analysts make sense of large text datasets and identify signals that are difficult to detect manually.
The research: toxic communication and early warning signals
Kaati’s work at FOI helped shape her current research direction. There, she and her colleagues developed tools to support analysts working with large amounts of online text. Working close to public authorities made one thing clear: while research prototypes can test new ideas, operational users need systems that are reliable, robust and well-tested. That experience continues to influence how she approaches her methods today.
At DSV, her research focuses on understanding online behaviour through data, divided into two main areas. One track focuses on toxic or harmful communication – language that targets a person rather than their arguments. In an interview with Universitetsläraren, Kaati explains:
“In political discussions, for example, there can be quite a harsh climate, but what we analyse is when people make personal attacks or talk about irrelevant things, such as derogatory comments about people’s intellectual capacity or appearance, when discussions should really be about the person’s work.”
The second track focuses on digital warning signs, signals that may indicate a heightened risk of violence. She continues:
“There, we don’t analyse toxic language but try to identify actual threats or someone describing a planned violent act. We also analyse psychological factors in individuals. Is this person expressing a perceived injustice?” She adds that when several warning signals appear together, the risk level increases and the material requires closer review by human experts.
This work is strongly interdisciplinary. Kaati collaborates with psychologists, criminologists and social scientists, while she develops the computational methods used to analyse large text collections. By building her own analytical models rather than relying solely on existing tools, she can tailor methods to the specific signals that analysts need to detect.
Practical applications and collaborations
Models based on Kaati’s research are now used primarily in the United States by schools and police departments. They help distinguish between harsh language and situations that may require follow-up — not by replacing human judgement, but by helping analysts prioritise which material needs closer review.
“It is not possible to sit and read everything that is written on the web. You need to sort through it. Computers can never replace people and their analytical skills, but we can help filter out what people need to read and understand,” Kaati says to Universitetsläraren.
Her methods also shape her teaching at DSV. The courses she has developed draw directly from her research and focus on online intelligence analysis and techniques for handling large volumes of digital text. As more work shifts into digital environments, these skills become increasingly relevant for future analysts.
International collaboration is another part of the work. During an exchange at Boston University, Kaati began a partnership with an American researcher specialising in threat assessment. Together, they analysed threatening online texts and worked with U.S. analysts to understand how risk levels are evaluated in practice. The collaboration has resulted in joint publications and involvement from the FBI’s Behavioral Analysis Unit, whose analysts contribute expert assessments to the research.
Digital safety in a changing landscape
Digital environments evolve quickly, and the volume of online material continues to rise. This makes it harder for organisations to recognise when everyday conversations begin to shift toward more concerning behaviour, especially when relevant signals may be scattered across large datasets.
In this context, analytical methods like those developed by Lisa Kaati give analysts a clearer starting point for their assessments. They highlight combinations of signals that might otherwise be overlooked and help ensure that potential risks are not lost in the speed and scale of online communication.
Kaati’s work focuses on parts of the internet that many prefer not to look at, but which can shape real risks and real consequences. By refining analytical tools and deepening insight into harmful online behaviour, her research contributes to a broader question: how societies can manage the risks that come with a more digital public life.
