Injecting Life into Visualizations for Biomedical Research

Visualization is an important data analysis method that allows scientists to explore a dataset without preconceived questions, and is thus crucial for hypothesis generation. Visualization is also essential in communicating research findings. Current visualization tools, however, have a crucial shortcoming: the interactive visual exploration process is not captured, which means that the analysis steps cannot be shared. Being able to reproduce visual analysis sessions and enabling third parties to understand, modify, and extend analysis sessions can have a significant impact on transparency, reproducibility, and innovation of analysis processes. In the first part of the talk we introduce our efforts towards making this vision a reality, demonstrated by means of examples from drug discovery. In the second part of the talk we will summarize our works on developing novel ways to visually analyze large and heterogeneous biomedical datasets. In particular, we will introduce solutions for exploring health-related sensor data and electronic health records, for comparing large tabular data, and for ontology-guided clinical data analysis.
