Molecular and BioPhotonics Group

Photonic techniques, which use light to image, detect, and manipulate molecules and biomolecules, are used to establish the optical measurement science, modeling, and simulation tools to enable the characterization and control of molecular systems.

Molecular and BioPhotonics research lies at the intersection of physics, chemistry, engineering, and life sciences. The ability to measure and quantify molecular systems is critical to realizing many applications in medicine, energy, and the environment.

The group's research effort focuses on the development of the following:

  • Development of new optical methods using spectroscopy and microscopy for enhanced detection of molecules and biomolecules;
  • Advancing the understanding of the interaction between biological systems and photons;
  • Diagnostic and clinical standards for validating the efficacy of biophotonics-based applications and understanding the fundamental physics underlying new biophotonics-based therapeutic techniques; and
  • Measurement standards for improving manufacturing quality and promoting acceptance of biophotonics technology
