Profile

I work on computational design and mechanics of structures: form-finding and optimisation, finite-element analysis and seismic design, with concrete shells as my current test case and embodied carbon as a design variable. My code is open and tested. My bachelor thesis was the full hand design of a four-storey reinforced concrete frame for a seismic site in Sichuan, to the Chinese codes. I now run two open research projects that build on it: ShellBench and ShellForm. Before this I spent two and a half years as a project engineer in precision manufacturing, running durability testing and root-cause analysis.

Interests: computational form-finding and structural optimisation of shells; seismic design and its embodied-carbon consequences; validated, reproducible structural software; machine-learning surrogates for structural design; lightweight structures for extreme environments.

Research projects

ShellBench: embodied carbon of thin-shell floors in seismic RC frames

  • Audited my thesis as the validation case: 16 input inconsistencies and 21 doubtful printed values logged, each with a recorded decision.
  • Rebuilt the thesis frame in OpenSeesPy under gravity, wind and earthquake, with GB 50010 member checks and automated tests on every change.
  • In progress: a design generator swept over storeys and ground acceleration, a shell-floor module checked against standard benchmarks, pre-registered hypotheses and an open dataset.

ShellForm: the carbon cost of seismic resilience in form-found concrete shells
