About

Rachel Martin is interested in the molecular factors determining protein stability, solubility, and aggregation.

Her lab develops and uses a variety of biophysical techniques, in particular nuclear magnetic resonance (NMR) instrumentation and experiments, for investigating the structures and dynamics of complex biomolecular systems.

One of her projects involves studying the crystallin proteins that provide the refractive power of the vertebrate eye lens. Unlike most proteins, which are continually degraded and recycled, these extraordinary proteins last a lifetime, remaining transparent at high concentrations. The Martin lab investigates the molecular structures of the individual proteins, the transparent hydrogel making up the lens, and the aggregates that form in cataract disease. They also investigate crystallin evolution, which requires comparative studies of lens proteins from other animals.
