Our paper, “Weingarten surfaces, the Codazzi equations and the membrane theory for the formfinding of tension structures, shells and vaults”, written together with  Chris Williams , has just been published in the International Journal of Space Structures in December 2025. It is freely available here:  https://journals.sagepub.com/doi/10.1177/09560599251388389?utm_source=researchgate.net&utm_medium=article It is well known that the Codazzi equations enable us to obtain a spaci

Within the course Digital Tools – Parametric Design , this yearly short workshop gives students the opportunity to design and fabricate their own lighting objects using Grasshopper3D and digital fabrication techniques. By working through the complete workflow, from computational model to physical prototype, the workshop emphasises how algorithmic design thinking can be directly translated into material and fabrication constraints, and how design decisions at the geometric lev

In May 2025, more than a year after my PhD defence, I took part in the official doctoral degree conferment ceremony at the Gothenburg Concert Hall, completed in 1935 and designed by Nils Einar Eriksson. The ceremony formally marks admission to the community of doctors and is rich in academic tradition. Receiving the doctoral hat and ring, symbols of academic freedom and commitment to scholarship, was a meaningful moment of reflection after several years of research and teachi

In the ending workshop of the course Digital Tools - Parametric Design we built constructed a cardboard grid shell constructed from an isogonal moulding surface. The course is part of the program Architecture and Engineering at Chalmers University of Technology. The workshop took place at Chalmers University of Technology in December 2024.   Design team: Emil Adiels, Benjamin Björksell, Oskar Nesset Mattsson, Erik Wigh and Chris Williams Participants: Architecture and engin

I am pleased to share that I have been awarded a postdoctoral research grant from Lars Erik Lundbergs Stipendiestiftelse. The grant will support a research project connected to my ongoing work on the design and analysis of hydrostatic masonry shells for new masonry bridges. The project will be carried out at ETH Zurich within the Block Research Group, whose research on structural form-finding and masonry construction provides an ideal environment for further developing this w

At the yearly IASS Annual Symposia at ETH Zürich in August, I presented one of our conference papers The structural behaviour of masonry bridges designed as hydrostatic shells . I was also a co-author of the paper The geometry of the flow of forces and moments across a shell written with Chris Williams. Both conference papers are available in the Proceedings of IASS Annual Symposia : https://www.ingentaconnect.com/content/iass/piass/2024/00002024/00000012/art00021#...

We got our paper The architectural application of shells whose boundaries subtend a constant solid angle accepted in the journal Computer Aided Geometric Design. The paper is freely available here: https://www.sciencedirect.com/science/article/pii/S0167839624000657 Our recent work shows that it is possible to generate a consistent principal curvature net  for a structural grid – that is, a grid composed of planar panels meeting at right angles – by using a special class of s

This workshop was part of the Digital Tools—Parametric Design course at Chalmers University of Technology in 2023. The participants were students in the Architecture and Engineering program. The goal was to explore how one can use a cable net and fabric as formwork for curved shells. The theme of the workshop was based on the research performed at ETH "Design process for prototype concrete shells using a hybrid cable-net and fabric formwork" by Veenendaal and Block https://b
