Researcher

Dimitra Tsovaltzi

Dimitra Tsovaltzi is a researcher in affective AI and technology-assisted learning. Her early research covered automated mathematical tutoring and learning from erroneous examples, and she later studied collaborative learning on Facebook. Her later research included mixed-reality teacher training, teacher-student co-regulation, and emotional models for industrial robots. Since April 2026, she leads DFKI’s MARSS project, which applies multimodal AI to help students identify misinformation and emotional manipulation in digital media.

Timeline

  1. 2003

    Automating tutorial hints

    She coauthors a 2003 workshop paper on automating hints for mathematical tutorial dialogue with Armin Fiedler.

  2. 2010

    A virtual chemistry lab script

    In 2010, she coauthors a study that uses a collaboration script to promote conceptual learning in a virtual chemistry lab. Her work also explores learning from erroneous examples.

  3. 2015

    Argumentation on Facebook

    She coauthors a 2015 study of argumentation scripts, individual preparation, and group-awareness support for learning on Facebook.

  4. 2021–2024

    MITHOS mixed-reality training

    DFKI’s MITHOS project runs from 2021 to 2024 and gives teachers mixed-reality practice for classroom conflicts. In 2024, she coauthors a chapter that presents the system’s four stages and a semi-automatic Wizard-of-Oz implementation.

  5. 2025

    A seminar on social computers

    At Saarland University, she teaches the summer 2025 seminar “How to build a social computer?”

  6. 2025

    The InCoRe model

    She coauthors InCoRe in 2025, an interactive co-regulation model for teacher-student communication that uses a psychological model to automate interaction with a virtual student.

  7. 2025

    Emotional co-regulation for robots

    In 2025, she coauthors BASSF, a model for socially interactive industrial robots that uses emotional signals to guide co-regulation between a worker, robot, and avatar.

  8. Since April 2026

    Leading the MARSS project

    Since April 2026, she leads DFKI’s MARSS project. It combines multimodal AI and explainable AI to help students identify misinformation and emotional manipulation in digital media.

From the biography.

  1. Nonprofit roles are 2.3 times as common in AI safetyIncludes DFKI. We estimate where people focused on safety, alignment and evaluation work. Nonprofit roles appear for 25.1% of safety people with known affiliations, compared with 11.0% in other areas.
  2. The top 10 organizations employed 22% of people shaping AI in 2025: 51% of company researchers and 21% of university researchersIncludes DFKI. We estimate the share of people shaping AI who worked at the top 10 organizations each year from 1955 to 2025, comparing concentration across companies, universities, and institutes and labs.
  3. The United States employs an estimated 48% of people shaping AIIncludes DFKI. We estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
  4. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes DFKI. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
