I'm hiring! Full PhD position open in Interactive Visual Data Analysis at University of Zurich!
About My primary research includes the characterization, design, and evaluation of visual-interactive interfaces to combine the strengths of both humans and algorithms in interactive machine learning and data science applications. My data-centered focus is on time series data as well as multivariate data. My technique-driven focus ranges from unsupervised to supervised machine learning including cluster analysis, dimensionality reduction, active learning, regression analysis, and classification. From a task perspective most of my work supports exploratory data analysis, i.e., sense-making, decision-making, and hypotheses-building for undiscovered data. Important application domains so far include climate and Earth observation, digital libraries, human motion analysis, service and energy network analysis, political decision-making, music classification, sports data analysis, stock chart analysis, as well as medical and patient-related research in particular.

Index Terms Information Visualization, Visual Analytics, Human-Computer Interaction, Data Science, Time Series Analysis, Exploratory Search, Visual-Interactive Learning, Active Learning, Semi-Supervised Learning, Interactive Machine Learning, Segmentation and Labeling of Time Series, Visual Cluster Analysis, Dimensionality Reduction, Multivariate Data Analysis, Mixed Data Analysis, Interactive Data Science

Short Bio Jürgen Bernard is an Assistant Professor of Computer Science at the University of Zurich (UZH), Switzerland. He is leading the Interactive Visual Data Analysis Group.
Jürgen Bernard studied Computer Sciences with focus on Computer Graphics and Bio Technology at the University of Technology of Darmstadt. His Diploma thesis in 2009 was about the visual-interactive cluster analysis using neural networks. He received his PhD Degree in 2015, when he was with Fraunhofer IGD. His thesis was about “Exploratory Search in Time-Oriented Primary Data”. In 2016, Jürgen Bernard started as a Post-doc researcher at TU Darmstadt at Interactive Graphics Systems Group, leading the Visual-Interactive Machine Learning Group. In 2019, Jürgen Bernard became a postdoctoral research fellow at the University of British Columba, Vancouver, Canada, where he joined the InfoVis group, led by Professor Tamara Munzner.

EuroVis Young Researcher Award

Jürgen Bernard has received the EuroVis 2021 Young Researcher Award! | 2021-06-15

In recognition of his outstanding contribution to the characterization, design, and evaluation of visual-interactive interfaces to combine the strengths of both humans and algorithms in interactive machine learning and data science applications. The Award is given to one young colleague, who has already made a significant contribution to visualization, and to the European Visualization community.

Best Paper Award at EuroVA 2021

Successful Collaboration with Fraunhofer IGD | 2021-06-14

We have received the Best Paper Award for our paper LFPeers: Temporal Similarity Search in Covid-19 Data. The paper formulates an interesting analysis problem of exploring similarity and dissimilarity in time series. As opposed to exploring the entire time series space, analysts choose inflection points to identify similarities in time up to a given point, and then explore how trends compare after this point in time. The notions of interactively are strong examples of how visual analytics can support analytical reasoning.
