Career 
Singh started his career at the RSAF Aeromedical center, and went on to serve as the head of Aviation Physiology Training. He set up the High-G training program for RSAF pilots based on a similar program that he had attended at the United States Air Force School of Aerospace Medicine. He was seconded to the Civil Aviation Authority of Singapore (CAAS) in 1993 and went on to become the first chairman of its Civil Aviation Medical Board. He had coordinated the international response to severe acute respiratory syndrome in 2003 and his actions had helped the aviation sector to recover post the outbreak. His studies focused on the understanding the spread of communicable diseases via air travel. During this period, he led the International Civil Aviation Organization (ICAO)'s Anti-SARS project for affected states. He also led the organization's committee to study the spread of communicable diseases through air travel. As a member of the CAAS task force on ultra-long-range flights, Singh had led health studies before launching the world's first ultra long-haul flight between Singapore and New York in 2004. Specifically, his work focused on studying the alertness of flightcrew on ultra long-haul flights. Some of his work with International Civil Aviation Organization was as a regulatory pioneer studying and managing human fatigue linked operational risks. Some of his studies would lead the organization to develop new standards and practices to address pilot and operator fatigue, including the Fatigue Risk Management System (FRMS). Singh also led the human factors working group as a part of the investigations of the Singapore Airlines Flight 006 crash in October 2000 that had killed 81 of the 179 occupants.
