His research interests were wide. In 1936 he and Dr G. Schepers took the famous paleontologist, Doctor Robert Broom, to the Sterkfontein caves, near Johannesburg, South Africa, where Broom made important discoveries of hominid fossils, Australopithecus africanus.

In his University teaching he saw epidemiology as a broad comprehensive subject studying the determinants of disease. From this point of view epidemiology includes the basic medical sciences, microbiology, environmental chemistry and clinical medicine. However, by 1975, in the English speaking academic world, epidemiology had become a narrow statistical subject, involved mainly with analysis and past epidemic surveys and clinical trials. The Department of Epidemiology and Biometrics grew and M.Sc. and Ph.D. Programs were developed.

Between 1950 and 1980 the pundits were claiming antibiotics would solve the problems of most infectious disease. The fact that bacteria develop resistance to medicaments was not considered. In 1973 le Riche and Dr. Michael Lenczner raised the importance of infectious and tropical disease imported into Canada by travellers, immigrants and refugees. Governments were not interested in these situations.

By 1981 it became clear that AIDS (acquired immune deficiency syndrome) was a serious infectious disease.
In 1953 he received a part-time commission in the Canadian Armed Forces, serving in the 23rd Field Ambulance, under Lieut. Col. David Thompson in Ottawa. In 1968 he became a member of the Defence Research Board and for many years he was Consultant on preventive medicine to the Defence Medical Council. Outside the University he served on many committees including those of the Ontario Medical Association and the Canadian Medical Association.

During 1966-72 he was on the Metropolitan Toronto Hospital Planning Council under the chairmanship of Dr. H. Hoyle Campbell, plastic surgeon, who with Dr. Shouldice, pioneered outpatient surgery in Toronto. Some of the excellent recommendations of the Council were carried out in 1998 and 1999. For many years he served as the Medical Research Council Associate Committee on Hospital Infections, Chairman Professor E.G.D. Murray. As a result of this association the book on "The Control of Infections in Hospitals" was published in 1966. Other committees were the Professional Education Committee of the American Public Health Association, Examiners Committee, Public Health and Preventive Medicine, Royal College of Physicians and Surgeons of Canada, Nursing Research Committee, Ontario Council of Health Care 1969, Physicians Services Inc. Research Grants Committee, Second International Conference on Agriculture, University of Reading, England, Committee, Canadian Cancer Research Foundation, Committee on Acupuncture, Ontario Council of Health, Report on Reorganization of the City of Toronto Health Department.

In the University he was on the Planning Strategy Committee, Planning and Priorities Subcommittee, and many others. Research on Medical Care included surveys on the work of Medical Officers of Health in Ontario, and the work of Optometrists and Ophthalmologists in Ontario.
For a few weeks he was visiting professor, Wayne County Medical School, Detroit and Distinguished Lecturer at Dalhousie Medical School.

In 1956 he first appeared with Dr. Arthur Kelly, Canadian Medical Association on a television program. This was the beginning of a 25-year career in radio, television and the daily press, which covered many aspects of health care, nutrition and communicable diseases, and medical politics. He became a good communicator, and public speaker. His academic interests were nutrition, infections, populations, and environmental destruction. He was a Fellow of the American Public Health Association and Fellow of the Royal Society of Tropical Medicine. For 18 years he was on the part-time staff of the Department of Family Practice and Extended Care at Sunnybrook Hospital. He was awarded the Defries medal and granted Honorary Membership of the Canadian Public Health Association.
