Making polymeric device surfaces visible with ZIF-8 coatings 
Metal-organic framework films bring dual-nuclear magnetic resonance contrast to polymer surfaces.
University of California, Los Angeles
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.
Metal-organic framework films bring dual-nuclear magnetic resonance contrast to polymer surfaces.
An effective-medium theory connects disorder and molecular orientation to macroscopic transport.
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.
From the symmetry of a molecule to the response of a living tissue and the evolution of a landscape.
Selective molecular recognition, gas exchange in the lung, and metabolic changes in living tissue.
How confinement, molecular motion, and interactions determine the behavior of heterogeneous matter.
How mechanical and biochemical cues shape T-cell activation, immune memory, and antitumor responses.
The relationship between molecular handedness, electronic wavefunctions, and spin-dependent transport.
Protecting coherence, generating entanglement, and controlling interacting spins in molecules and materials.
Nonlinear changes in gene expression and DNA methylation, and what they reveal about age and biological variation.
How terrain and climate interact to control landslide susceptibility, and when predictions transfer between regions.
