Our lab is interested in development of novel optical and ultrasound based imaging and sensing technologies, and their applications to biomedicine. A topic we are particularly interested in is photo-acoustic imaging which is also referred to as opto-acoustic imaging. Combining the advantages of light and sound, photoacoustic imaging techniques can achieve high-sensitive imaging in deep biological samples with excellent spatial resolution. Potential clinical applications include inflammatory arthritis, breast cancer, prostate cancer, liver conditions, eye conditions, bowel disease, bladder cancer, and brain disorders. We are also interested in developing and application of nanoparticle agents either as contrast enhancers for diagnostic imaging or as carriers for drug delivering or both. These nanoparticles can be based on non-organic metallic materials such as gold or organic hydrogel. Besides imaging, our lab is also interested in novel treatment technologies involving light and ultrasound, e.g. ultrasound-enhanced photomechanical therapy.
