I am a PhD candidate in the Computer-Human Interaction Software Engineering Lab (CHISEL) at the University of Victoria, Canada, since September 2007. My supervisor is Dr. Margaret-Anne Storey. I received a Masters degree in Computer Science (Diplom-Informatiker) at RWTH Aachen University, Germany, in February 2007.
 
For my PhD, I am researching user interfaces supporting information visualization novices in visualization construction and coordination. My other areas of interest are information visualization for the masses and in general, visual analytics, human-computer interaction, end user development and semantic web technologies.

Open Source Projects

I am currently an active contributor to the open source projects listed below. Projects to which I have contributed in the past can be found on my Sourceforge profile.


Choosel [ code.google.com/p/choosel/ ]

Choosel is a framework that supports the creation of web-based information mashup environments. These mashup environments facilitate the flexible recombination of information in different views such as maps, timelines and graph viewers. Users without any programming expertise can remix information using drag and drop interaction and explore data sets. The workspaces (mashups) can be stored and shared among users.

BugzillaMetrics [ www.bugzillametrics.org ]

BugzillaMetrics is a tool for the calculating change request metrics. I created its first version as part of my Master's thesis 2006/2007. Its main characteristics are the specification of metrics by the users, separation between metric specification and data retrieval, an event driven algorithm, transparent execution optimization and an abstraction of its data sources.


Nomad PIM [ www.nomadpim.org ]

Nomad PIM is an Eclipse RCP based personal information manager. I started the project in 2005. My goal was to create a personal information manager that can be extended and customized for personal needs in the way that the Eclipse IDE can be customized for development in different domains. Since November 2009, Nomad PIM is not actively developed any more.
