Probing Biomineral Formation through Novel Laser Imaging Polarimetry

Rebecca Metzler and Kiko Galvez (Physics & Astronomy) received a two-year, $57,000 grant for their project “Probing Biomineral Formation through Novel Laser Imaging Polarimetry,” which will combine the physical optics involved in diagnosing complex light forms with the biophysical research of the biomineral surfaces made by various mollusk species. The colorful inner surfaces of mollusk shells are an example of the extraordinary biominerals that are produced by living organisms. These shells have a complex surface structure composed of micro-crystals intertwined with and cemented by bio-organic compounds. In an innovative combination of different approaches, Metzler, Galvez, and their students will study the polarization of the iridescent light reflected by the shells to obtain information about the composition and structures that give them their remarkable physical properties. Rebecca and Kiko are each bringing very different approaches and perspectives to this very creative collaboration, and together they will develop exciting new ways of visualizing and understanding complex biological materials,” said Picker ISI Director, Damhnait McHugh.
