As a Medical Physicist, my research is on radiation dosimetry, treatment planning and patient communication. I use advanced computer methods to develop precise and accurate dose delivery process in radiation oncology. These include using Monte Carlo method to predict radiation dosimetry in radiotherapy, big data analytics to evaluate radiation treatment plan, and AI/machine learning to create chatbot for radiotherapy knowledge transfer to the patients. I am keenly interested in helping cancer patients to receive fast, safe, and high-quality radiation treatment, taking advantage of recent advances in computer technology.
