My name is Sebastian Baltes and I'm a researcher, teaching assistant, and Ph.D. student at the Software Engineering Group of Trier University in Germany. My research aims at thorougly analyzing software developers' work practices and use the gained knowledge to:
- identify requirements for new tools supporting developers,
- build, evaluate, and compare new and existing tools,
- and communicate developers' needs and opinions to the research community.
Most empirical studies I conduct follow a mixed-methods approach, combining qualitative and quantitative methods. I'm esspecially interested in interdisciplinary research, involving theories and methods from the social sciences (e.g., grounded theory, ethnography) and psychology (e.g. theories on expertise development and personality). To complement qualitative results derived from interviews, oberservations, and online surveys, I apply data-mining techniques on open source software projects, e.g. hosted on GitHub. Besides, I'm interested in information visualization and in particular in visual analytics, i.e. how interactice visualizations can support users in analyzing data.
