Molecular and BioPhotonics research lies at the intersection of physics, chemistry, engineering, and life sciences. The development of photonic techniques, which use light to detect, quantify, and image molecules and biomolecules, are used to establish the optical measurement science, modeling, and simulation tools critical to realizing many applications in medicine, energy, and the environment.
The Molecular and BioPhotonics group research efforts focus on the development of the following:
New photonic spectroscopic and imaging techniques for enhanced detection of molecules and biomolecules;
Measurement standards for improving manufacturing quality and promoting acceptance of optical medical imaging technologies; and
The application of photonics techniques to real world problems.
