Getting to HIIT Otaniemi

As from August 1, 2018, I will be joining the Human-Centred Computing (HCC) Section (led by Prof Kasper Hornbæk) of the
Department of Computer Science (DIKU) at the University of Copenhagen as an Assistant Professor of Information Visualization.
My new email address will be lm (at)

Research Interests

General interests: information visualization, visual design and analytics, and human-computer interaction.
In particular, diagram design and layout using computational and model-based methods based on principles of human perception and cognition to optimize the visualization for the human user. Also, biological data visualizations and set visualizations.


I am a postdoctoral researcher at the Helsinki Institute for Information Technology (HIIT) and Aalto University.
I am member of the Probabilistic Machine Learning Group led by Prof Samuel Kaski, but contribute also to the User Interfaces Group led by Prof Antti Oulasvirta and Ubiquitous Interaction Group led by Prof Giulio Jacucci.
Currently I work with professors Kaski, Oulasvirta and Jacucci on multiple interdisciplinary projects at the intersection of probabilistic machine learning, cognitive science, human-computer interaction, and data visualization, to devise systems that facilitate analysis of large complex datasets, such as the medical data curated by the Institute for Molecular Medicine Finland (FIMM).
I am also an Honorary Research Fellow in the School of Computing, University of Kent, UK where I was previously a Research Fellow following the completion of my PhD at the same School. My PhD thesis, titled 'Visualizing Set Relations and Cardinalities Using Venn and Euler Diagrams', was commended as a 2016 CPHC/BCS Academy of Computing Distinguished Dissertations runner-up, awarded at the prestigious BCS Roger Needham Lecture (press). Further details are available on my University of Kent webpage.
