Bouchard Labat UCLA

We investigate how structure and interactions shape spin, molecular transport, and biological responses. Our work spans chemical physics, immune microenvironments, biological aging, and geophysical systems.

Our perspective

Structure shapes behavior.
Across scales.

A molecule’s handedness can influence spin-dependent transport. A material’s pore geometry changes how molecules move. The mechanics of a cell’s surroundings can alter its immune response.

We study these connections between structure and dynamics across chemical, physical, and biological systems. Our work brings together fundamental chemical physics, biological mechanisms, and models that can be tested against observations.
