About myself
Dear reader,
Thank you for your interest in my work. In general, my research revolves around designing scalable AI-based Requirements Engineering systems for end-users. That's a very high-level description. Specifically, that means that I am looking at how to learn something about what users of software want or need - by providing end-users with tools to voice their requirements and supporting analysts and researchers with analyzing qualitative data.
Sounds interesting? Do you want to discuss research, theories, or are a student interested in the topic and looking for a thesis supervisor? Feel free to contact me anytime.

Now hiring! |
If you are looking for an internship or you what to learn more about the (IT) consulting industry, let me know. |
