KI im Krankenhaus – Vom Hype zur praktischen Anwendung

Erste Informatik-Masterstudiengang Absolventin der Universität zu Köln

Lena Jacobi hat als erste Frau den Informatik-Masterstudiengang an der Universiät zu Köln abgeschlossen. Der Masterstudiengang wurde zum ersten Mal im Wintersemester 2022/23 in Köln angeboten. Ihre Masterarbeit mit dem Titel "Guidelines for Semantic-Based Colors for Combined Categories" wurde von Prof.'in Dr. Tatiana von Landesberger und Laura Pelchmann betreut.

Dagstuhl Seminar 24091 - Reflections on Pandemic Visualization

The Dagstuhl Seminar 24091 "Reflections on Pandemic Visualization" took place from February 26, 2024, to March 1, 2024. Organized by Prof. Tatiana von Landesberger and three other organizers, the seminar provided a platform for exchange among 37 researchers from 30 different institutions worldwide.

Challenges and opportunities of the COVID-19 pandemic in the field of data visualization were reflected upon, promoting collaboration between the visualization community, modeling experts, epidemiologists, infection control experts, and end users. Lessons from the COVID-19 pandemic were drawn to improve the response to future global emergencies.

As a result of the seminar, a book will be published summarizing the insights and experiences gained, and providing answers to the research question: "What are the learned lessons and experiences of the pandemic in terms of data visualization that will best help the response for future pandemics?"

RISK PRINCIPE – Risk prediction for infection control and treatment in hospitals

We are pleased to announce our participation in the RISK PRINCIPE project.
The project started on July 01, 2023.

Hospital-acquired infections, especially nosocomial bacteremia, pose a significant problem for patients and the healthcare system. The RISK PRINCIPE project aims to address this issue. It utilizes standardized data and computer-based risk assessment to develop reporting and monitoring apps, along with a warning app for risk prediction. The project integrates data from various sources, including the German Medical Informatics Initiative, and engages experts from various disciplines. The solutions developed aim to be sustainable and transferable, bridging the gap between individual risk assessment, bacteremia, and infection control to enable effective prevention.

As the lead of the Visualization Methodology and Evaluation work package, we will develop novel interactive visualization techniques based on an initial requirements analysis. Users will be able to analyze patient risk factors using the newly developed visualizations. In addition, a dashboard for risk monitoring with an alarm function will be implemented.

WarmWorld Easier

We are pleased to announce our participation in the WarmWord project.

The project started on 01 September 2022 and consists of 4 modules: Better, Faster, Easier, and Smarter.

As part of the Easier Module, which started on 01 March 2023, we are working on the third goal of the WarmWorld project:
"An integrated workflow that exposes the information content of the ICON modelling system alongside IFS-based solutions and observational data in ways that leverage the intuition of users and supports innovation."

We will develop novel interactive visualization techniques that enable exploration and comparison of model and observational data and their uncertainties.
New visual designs will be explored and interactive visualization will then be implemented prototypically.
