Research Interests

• Development of non-destructive diagnostic methods to identify laser-induced damage precursors in optical materials and monitor the effectiveness of damage prevention, repair, and containment strategies
• Physical mechanisms of energy deposition by high average power lasers in optical materials and subsequent material response
• Use of optical spectroscopy for noninvasive in vivo identification, characterization, and monitoring of the treatment of pathological or injured tissue
