Physics and Mathematics


Lucas leads an experimental research group that studies pattern formation and complex fluids. He is also currently teaching image processing for forensic students  and the first-year physics lab course. He has previously taught courses in environmental physics, non-linear dynamics, mechanics, soft matter physics, and the history of physics.

Career overview

Prior to joining the faculty at NTU, Lucas was a research group leader at the Max Planck Institute for Dynamics and Self-Organisation. During this time, he taught at the University of Göttingen, where he also habilitated. He obtained his PhD from the University of Toronto for his work on columnar joints, like those of the Giant’s Causeway, and was a post-doctoral fellow at the University of Cambridge, where he studied how colloids, such as mud or paint, dry and crack.

Research areas

Along with his research group, Lucas studies complex fluids and complex solids – materials that consist of more than one phase of matter, mixed together. This covers a diverse range of topics and questions, but is generally held together by a few simple themes:

  • connecting the microscopic structure of such materials to their macroscopic properties,
  • understanding mechanical instabilities (e.g. fractures, wrinkling), and
  • applying these results in a broad, interdisciplinary way (e.g. polymer films to reptile scales or fossil biofilms; mud cracks to Martian permafrost).

Basically, this research asks the question: Why is the universe not boring?  Or, why is there so much structure, order, and pattern to life and nature, rather than a flat featureless expanse?  In response, his work has focused on using the tools of solid mechanics, pattern formation, and the physics of complex systems, to form bridges between controlling what happens on one length scale, and creating a response on another scale (or interpreting how a response happened).   Some examples include:

  • wrinkling of curved sheets – how does geometry control shape?
  • porous media flows, studied with microfluidic techniques.
  • geophysical patterns, like salt polygons, patterned ground, or columnar joints.
  • Fracture patterns, such as desiccation, biogenic or hydraulic cracks.
  • Colloidal dispersions, for example the dynamics of drying paint.
