My research interest is in imaging and characterization of ocular tissues with ultrasound alone or in combination with optics. I am using high-resolution ultrasound to map the layers of the cornea to detect changes indicative of early keratoconus. I am investigating the use of pulsed lasers in combination with ultrasound in a process called photoacoustic imaging to visualize light-absorbing tissue structures, such as the microvasculature. I am also studying the use of ultrasound to remotely palpate tissues such as the cornea or retina to non-invasively probe their elastic properties. Other areas of research include ultrasound contrast agents and advanced probe design and signal processing for improved sensitivity and resolution in ultrasound images.
