Gaia Pavoni and Thomas Höllt win VRVis Visual Computing Award


Vienna COMET Center VRVis recognizes applied visual computing research from Europe that supports marine ecology and cell biology with a newly launched science award.

Visual computing is a cross-sectional technology that transforms data into information and images and finds application in almost all industries. It is one of the key technologies for the implementation of human-centric digitization, as it creates visual interfaces between humans and computers. The Vienna-based research center VRVis Zentrum für Virtual Reality und Visualisierung established the first pan-European VRVis Visual Computing Award in 2022 to highlight visual computing solutions that contribute to the achievement of the UN's 17 Sustainable Development Goals. The international, seven-member jury gave equal recognition to Gaia Pavoni from the Institute of Information Science and Technologies "Alessandro Faedo" (ISTI-CNR) and Thomas Höllt from TU Delft. The award ceremony will take place on January 26, 2023, as part of the Visual Computing Trends Symposium at Tech Gate Vienna.

Visual computing research award focuses on global development goals

The first VRVis Visual Computing Award focuses decidedly on the United Nations Sustainable Development Goals (SDGs), highlighting the important contributions that visual computing is already making toward meeting each goal. "The high-quality submissions from all over Europe show the tools and solutions that visual computing is bringing to the table in the field of human-centered medicine, biodiversity, sustainable cities, climate change adaptation, or inclusive communication," says Katja Bühler, scientific director of VRVis. "We are proud to award Gaia Pavoni and Thomas Höllt for their important research achievements with high application orientation and to raise public awareness about the role of visual computing."

Coral reef visualization supports marine ecology

Gaia Pavoni of ISTI-CNR receives the VRVis Visual Computing Award in recognition of her outstanding visual computing techniques for monitoring underwater worlds, which supports SDG 13 "Climate Action," SDG 14 "Life Below Water," and SDG 9 on "Innovation."

Coral reefs are essential resources for our planet, hosting 25% of marine biodiversity. However, there has been a rapid and massive coral die-off in recent decades – invisible to the world above. To make the underwater world more visible to science and people, information engineering expert Gaia Pavoni developed the open-source AI-based annotation tool TagLab that enables coral reef monitoring and greatly simplifies the work of marine ecologists, allowing better research on the effects of climate change on marine habitats such as coral reefs.

Gaia Pavoni completed her Ph.D. in "Information Engineering" at the University of Pisa, Italy, in 2020. She has been a Research Fellow at the Italian Visual Computing Lab ISTI-CNR since 2014, with numerous scientific stays abroad in Florida, Moorea, San Diego, or Marseille. So far, she has received several Best Paper Awards for her scientific publications.

Visual analysis in cell biology

Thomas Höllt from TU Delft receives the VRVis Visual Computing Award for his essential research contribution in the field of visual analysis of single-cell data, which contributes to SDG 3 "Good Health and Well-Being" as well as SDG 9 on "Innovation".

Novel methods for capturing and analyzing protein and gene expression on single-cell data have revolutionized systems biology and cell biology in recent years, providing insights into the interplay of cellular functions of living organisms. In order to work efficiently with the acquired data despite their enormous size and complexity, Thomas Höllt and his team developed new visual analysis methods and software frameworks called Cytosplore, ImaCytE, and SpaCeCo to interactively explore single-cell data. These innovative visual analysis tools and techniques make the vast amounts of data in the health field, e.g., in the study of autoimmune diseases, cancer, or parasitic and viral infections such as Covid-19, accessible to physicians and scientists in a completely new way.

Thomas Höllt completed his Ph.D. at the King Abdullah University of Science and Technology, Saudi Arabia. After positions in Vienna, Salt Lake City, and Delft, he moved to Leiden University Medical Center as Assistant Professor in 2017 before returning to TU Delft in 2020. He has published over 50 peer-reviewed publications, including the winning paper for the Dirk Bartz Prize for Visual Computing in Medicine in 2019, and is a member of the Eurographics Association.
