Biomaterials cover a broad range of materials that provide an interface between the biological and physical worlds. These include synthetic materials that repair, restore and replace biological functions or biologically-inspired/derived materials that provide new physical, electrical or optical functions. At UCSB, BMSE researchers are actively involved in biomaterial research including: drug and gene delivery carriers, biologically-inspired adhesives, tissue engineering, synovial fluids in joint lubrication, structural materials based upon the mechanical properties of biopolymers and biomembranes.
Physical foundations of macromolecular technology: self-assembly, polymer mechanics and stability, energy transport, diffusion, and DNA-based nanotechnology.
Molecular mechanisms of ribosome pausing during protein synthesis and recruitment of SsrA (tmRNA) to stalled ribosomes.
Intermolecular and surface forces in colloidal and biocolloidal systems and materials, adhesion, and friction.
RNA folding and evolution; nucleic acid-based bionanotechnology and biomaterials; emergence of complexity in living systems.
Molecular mechanisms of Alzheimer's disease; structure/function studies on tau using NMR, spectroscopic, biochemical, molecular, and cell biological methods; role of cdk5/p35 in neuronal development and signal transduction.
