MingJai Dai, Ph.D. died on Feb 7, 2019. He was 72 years old.

A native of Guangzhou in China, Dr. Dai obtained a doctorate in biomedical engineering in Australia with Ian Curthoy and G Michael Halmagyi before pursuing, in 1989, fellowship training with Bernard Cohen at Mount Sinai hospital in New York. Dr. Dai stayed there for 30 years. In 1992, Dr. Dai was appointed the director of the human vestibular laboratory, through which Dr. Dai provided clinical testing of dizzy patients. In his research, Dr. Dai demonstrated recognizing the importance of orientation to the spatial vertical . This insight led to the development of a treatment for mal de debarquement syndrome (MdDS), which he hypothesized to be caused by maladaptation of the vestibulo-ocular reflex. He had patients view a moving pattern of stripes while rocking their heads.

Dr. Dai was committed to patient care and he often worked on the weekends to accommodate patients who came from all over the world for his treatment of MdDS.
