I am part of the Caleydo Project, an open source biomedical visualization framework. Caleydo is joined work of Johannes Kepler University Linz, TU Graz, Harvard School of Engineering, and Harvard Medical School.
My PHD topic is about Guided Visual Exploration of Heterogeneous Data. As Thomas and Cook highlighted in their book Illuminating the Path: The Research and Development Agenda for Visual Analytics: the grand challenge has shifted from the acquisition of the data to its analysis. The idea of my thesis is to develop visual guidance techniques that guide analysts to interesting part of their data, computed via data mining algorithms. The challenges are manifold and raise interesting research questions.
