Dr. Lawrence Lau graduated from the Chinese University of Hong Kong in 2014. He has undergone further postgraduate research study with special interest in arthritis and joint replacement and was awarded Doctor of Philosophy (PhD in Orthopaedics and Traumatology) in 2022. He completed the Joint Specialty Fellowship Examination in year 2021 by the Hong Kong College of Orthopaedic Surgeons and Royal College of Surgeons of Edinburgh. And he obtained his fellowship from Hong Kong College of Orthopaedic Surgeons, Royal College of Surgeons of Edinburgh and Hong Kong Academy of Medicine. He subsequently joined the University of Hong Kong in 2023 as Clinical Assistant Professor. An active surgeon and researcher, he has been invited to be Hong Kong Orthopaedics Association Ambassador to discuss his arthroplasty research in Singapore Orthopaedics Association and Japanese Orthopaedics Association.

He has won The David Fang Trophy as first author for the Best Adult Joint Reconstruction Specialist paper and Dr. Yeung Sai Hung Award as co-author in the Adult Joint Reconstruction Chapter of Hong Kong Orthopaedics Association. And his research on adult joint reconstruction has won a Gold Medal with Congratulation of the Jury, and a Bronze Medal in the 48th International Exhibition of Inventions Geneva. He is interested in developing cross-disciplinary collaboration with other medical, science and engineering experts to tackle problems on aging, osteoporosis, sarcopenia, arthritis, and joint replacement. He is regularly involved in undergraduate and postgraduate medical education, and experienced in nurturing medical students, juniors, and students from other disciplines to conduct independent research to develop their careers. He is also interested in promoting health knowledge to the public and serving in low resource areas.
