Eye diseases are more prevalent in aging populations and are attracting increasing attention from the pharmaceutical industry. For many people, conditions that affect the retina require monthly injections of drugs into the eye. In addition to patient discomfort, this increases the risk of infection and cataracts. Prof Chau’s research team has developed injectable biomaterials of hydrogel and nanoparticles that are long lasting, thus cutting down on the number of undesirable injections and reducing the healthcare cost. Her lab has also patented a needleless method that employs ultrasound to deliver drugs into the eye, and this technology is now being commercialized by a former student. For Prof Chau, “sight” has yet another meaning – Student Innovation for Global Health Technology (SIGHT). This new education platform, founded and currently directed by Prof Chau, aims to transform the collaborative creativity of students into a tangible impact on public health under low-resource conditions. She will introduce her research projects and activity of SIGHT.
