Perhaps you should try some spelling variations:
john edmondson » john edmonston, jonathan edmondson, joseph edmondson
john edmunds » john edmund, john edwards, von edmund
john edmonds » john symonds, von edmonds, john edmund
epidemiologist » epidemiologists, epidemiologie, epidemiologic

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((john edmunds) OR (john edmonds))) OR (hon edmund))) OR (john edmondson)) (epidemiologist).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((john edmunds) OR (john edmonds))) or (hon edmund))) or (john edmondson)) (epidemiologist)".
• Adding a wildcard symbol may retrieve word variants: ((((((john edmunds) OR (john edmonds))) or (hon edmund))) or (john edmondson)) (epidemiologist)*.
