“Light is almost an ideal form of electromagnetic waves to probe and treat biological tissues,” says Dr. Lai. “Its applications, however, are limited due to the inherent strong scattering of light in tissue. Different from the traditional wisdom that treats multiple scattering of light as a problem, it could also be part of the solution. Our long-term research goal is to better understand the principles and mechanisms of optical scattering and optical speckles, and break the rules and limitations of visualizing, interrogating, treating, and controlling biological tissue by using light.”
Dr. Puxiang Lai is an Assistant Professor in the Department of Biomedical Engineering, Faculty of Engineering. His research is mainly focused on high-resolution deep-tissue optical focusing, imaging, treatment, and stimulation as well as their applications in biomedicine.
