Karsten Nefs

Karsten Nefs is a postdoctoral researcher at Eindhoven University of Technology's Built Environment school, specializing in Concrete Structures. His work focuses on 3D concrete printing and strain-hardening cementitious composites (SHCC), bridging microstructure analysis with full-scale structural applications.

Research Highlights:

• Developed analytical models for orientation-dependent properties of 3D printed SHCC across multiple scales (2024)
• Investigated length-scale effects on failure modes and strain hardening in printed composites (2024)
• Applied SHCC-helical reinforcement integration to a spiral staircase case study (2023)
• Developed neural network-based image segmentation for fibrous composite microstructures (2023)

Collaborations: Works with Prof. Theo Salet, Dr. Freek Bos, and international researchers. Active in RILEM conferences and interdisciplinary projects combining materials science with structural engineering.
