I am an Associate Research Scientist at the Khoury College of Computer Sciences at Northeastern University in Boston, MA. I received a PhD in Network Science/Data Science from Technical University of Denmark.

The core of my work is auditing platforms and their algorithms for fairness and privacy. Together with my collaborators we investigate systems that are optimized for corporate profit yet drive many aspects of our daily lives. All too often we find these systems have (possibly unintended but often predictable) side effects that bring harm to individuals and the society.

Before diving into algorithm audits I worked on analyses of behavioral data collected from smartphones to model human mobility, spread of diseases, development of relationships, and to predict life outcomes. This experience made me closely aware of and alert to the privacy risks associated with accumulation of personal data.
