Hi there! 👋 I'm Holger.

I'm learning, experimenting, and working with web technologies since the early 2000s.

🧑‍💻 Currently, I'm Lead Researcher and Software Engineer at datavisyn. Together with my team I develop novel visual analysis tools for cancer research, drug discovery, and other application areas using web technologies and frameworks such as React, Redux, and Fast API.

🧑‍🏫 I'm also teaching Interaction Design, Usability Engineering, and Interactive Data Visualization with D3 at the University of Applied Sciences in Hagenberg, Austria. I enjoy well designed products that are easy to use and data visualization that scales.

👨‍🎓 I finished my PhD at the Institute for Computer Graphics at Johannes Kepler University in 2019. My scientific areas of interest include visualization and visual analytics of multi-attribute and temporal data. I'm still co-authoring papers with other researchers from academia on projects to create new visualization and visual analytics approaches that can improve our products in a later stage. You can find a list of my publications on my Google Scholar profile.

If you would like to know more about me and my work, take a look around here on GitHub or connect with me on LinkedIn or Twitter.
