is a doctoral researcher at the TT Professorship for Digital Fabrication at TUM with background in architecture. In her research, she explores site-specific digital design tools for robotically fabricated real-size mono-component building envelopes. As part of her association with the AMC, she is part of the interdisciplinary teaching team for the project “From Additive Manufacturing to Architecture” in 2022 and contributes as Design Lead for the collaborative demonstrator “Breuer x AM”.
