He returned for further Postgraduate training (and received his second board certification) in Preventive Medicine specializing in Occupational Medicine from Thomas Jefferson University in Philadelphia. After completing his first medical residency, he worked in the Emergency Department setting (full time and part time) for eight years. For the last sixteen years, since beginning his training at Johns Hopkins, Dr. Cheung has been working full time in Occupational and Environmental Medicine, and Public Health consultation.

In June 2000, he was designated as the State Medical Director for the State of Maryland agencies and State employees and in that capacity has worked closely with the State of Maryland (and local municipalities and many large corporations) in building a safe, healthful and productive workplace. Dr Cheung’s subspecialties are Respiratory Environmental Medicine, Indoor Environmental Quality investigations, Risk communication and Medical Advisory services. He has worked well and collaboratively with management, employees, unions and other stakeholders. He has extensive experience working on issues of Indoor Environmental Quality on matters related to molds, microbial, chemical and other contaminant exposures in commercial buildings, manufacturing plants, schools, and various public and residential facilities. His philosophy is a preventive medicine approach, i.e., to design, educate, develop policy to prevent occurrence or reoccurrence of exposures, injuries and illnesses. The approach is to assess the science and investigate the root cause(s) of environmental diseases, injuries, illnesses or accidents; we can develop an integrated plan of action for prevention and/ or resolution of the problem. For Indoor Environmental Quality issues in particular, he believes that there is good science, junk science and those who stretch scientific evidence and/ or scientific techniques. He has expertise in a wide range of Environmental and Occupational health issues including matters related to asbestos, lead, various chemical agents, solvents, metal washing fluids, mold, infectious agents, physical or mental impairments, and the validity of the scientific methodologies employed. He routinely lectures at academic and medical society meetings, and presents at many venues to lay audiences. He has served as scientific expert in many administrative and legal proceedings, and routinely testifies to State Legislators. Notably, Dr. Cheung was on the Maryland Governor’s Task Force on Indoor Air Quality. The Task Force met for ten months reviewing the latest literature, data, testimonies of experts and patients, best practices, etc and generated a set of recommendations to the Governor and the State Legislature on July 1st, 2002.

He currently serves on the Baltimore City Healthy Homes Advisory Board, having been invited by the Health Commissioner of Baltimore City. He has clinical privileges at Mercy Medical Center in Baltimore, Maryland, and at a Department of Defense (DOD) agency’s Medical department.
