After practicing as a radiation therapist for 10 years in the Queen Mary Hospital and Queen Elizabeth Hospital, Professor Maria Law received a government scholarship for teacher training in the UK in 1982. She started teaching in radiation therapy technology starting 1983 upon her return to Hong Kong, first in the School of Radiotherapy of the then Hospital Services Department in Hong Kong, then in the Hong Kong Polytechnic University for 20 years before joining the Tung Wah College. She is at the same time the consultant (Medical Imaging and Radiation Therapy) of the Hong Kong Sanatorium and Hospital.
Professor Law actively engaged herself in professional activities locally and internationally. Locally, other than starting up the local radiation therapy association, she is the founding President of Hong Kong College of Radiographers and Radiation Therapists in 2008 and continues to serve in that capacity until now. Internationally, she was the Vice President (Asia-Australasia) of the International Society of Radiographers and Radiological Technologists from 2006 to 2014, after which she was re-elected as the Director of Education of the same society.
Professor Law had also been appointed to serve in various government professional boards such as the Radiographers Board and its committees as well as the Registration Committee and Examination Committee of the Chinese Medicine Council of Hong Kong, In the Sir Edward Youde Memorial Fund for Research Students, she had been a member and a chairman of the interview panel.
Over the years, Professor Law received a number of Research Awards locally and internationally. She had been consultant to two Hospital Authority projects and is often invited as keynote speakers for international conferences. For her numerous contributions to the profession, she was admitted to the Hong Kong College of Radiologists as an honorary member.
