Patrick works on the application of adaptive optics to laser micro-fabrication. He uses femtosecond pulse lasers to manufacture three dimensional devices inside transparent materials, applying adaptive optical techniques to enhance precision and/or speed.
Areas of particular interest are devices inside diamond; liquid crystal photonics; and microscope calibration.
