Designing structures that do more with less.
I study how structures can remain safe under variable loads while using less material. My work connects shakedown mechanics, topology optimization, and physics-informed AI to turn nonlinear structural behaviour into practical design methods.
Shape follows strength.
Topology optimization redistributes material around genuine load-bearing capacity—not elastic convention alone.
Mechanics learns.
Physics-informed neural networks encode equilibrium, yield, and residual stress directly into intelligent design.

01
Strength-aware design
Topology optimization beyond the elastic limit
A gradient-based framework integrates shakedown analysis with topology optimization, redefining effective material through total shakedown stress rather than elastic stress alone.

Learning strength from physics, not labels alone
Physics-informed neural networks encode equilibrium, yield conditions, and residual-stress relationships directly into the learning process for faster structural assessment.
