The Human-Centered Data Science research group (HCDS) focuses on the human factors in the conception, use, and understanding of data. Positioned in the intersection of data science, social science, HCI, and CSCW we are interested in understanding and exploring human practices enabled by technology. We combine both quantitative and qualitative methods, and work with computational methods such as statistics, machine learning, network analysis together with qualitative methods such as ethnography, interviews, and observations. Our research aims to contribute to often overlooked human-centered dimensions of data science such as individual differences, domain-expertise, design implications, and societal impact. Within HCDS we work across several topics, including digital media platforms, information visualization, crowd sourcing, affective computing, behavioral modeling, and societal challenges related to digital infrastructure more broadly.


Luca Rossi
Associate Professor

Luca Rossi’s research connects media and communication studies with computational approaches. He explores how digital technologies and social media impact complex social processes such as participation, activism, politics and, more recently, information propagation.

Søren Knudsen
Assistant Professor

Søren Knudsen’s research focuses on information visualization and human-computer interaction. He is interested in supporting people in understanding, making sense of, and discussing data in face-to-face and online contexts, for example supported by large or multiple displays and social media.

Aske Mottelson
Assistant Professor

Aske Mottelson’s research is in the intersection between psychology and data science. Aske conducts experiments and employs methods from statistical analysis and behavioral modeling to expand our understanding of humans through the use of technology. Aske is currently interested in (among other things) affective computing, sensing techniques, and virtual reality.


Öykü Yilmaz is a MSc Student in Software Design. She is designing a prototype to improve the self-awareness of Twitter users by visualizing the consequences of their actions when sharing or retweeting a post. The project build on mixed methods and aims both at measuring the actual users’ understanding of the consequences of their network behavior as well as testing several visualization strategies to improve it.
