My major research interests include:

• Antimicrobial photodynamic therapy (the synergism of photoactive agents and visible light for targeting microorganisms); and
• The impact of blue light on dental plaque growth and host innate response dynamics.

My research accomplishments are:

• The development of a new direction in Oral Research by establishing a unique research program in the field of Photomedicine with the foundation of the Applied Molecular Photomedicine Laboratory (AMPL) at The Forsyth Institute in 2003, a translational research laboratory – unique of its kind nationwide – with strong collaborations with outstanding clinicians, scientists, and engineers.
• The Scientific Foundation of PhotOral, Inc. (2011), a science-based company in Boston to develop a novel intraoral device that emits light in the blue region of the electromagnetic spectrum in the appropriate wavelength and dosimetry for selectively targeting potentially harmful dental plaque microorganisms.
• The establishment of the Nano-Photo-Medicine Initiative that brought Photomecidine and Nanotechnology together.
• The development of photodynamic therapy (synergism of a photosensitizing compound and red light) as an adjunctive technique to standard chemo-mechanical endodontic disinfection.
