Perhaps you should try some spelling variations:
jonathan edmondson » john edmondson
john edmunds » john edmonds, john edmondson, hon edmund
john edmund » bohun edmund, hon edmund, von 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 edmund))) OR (jonathan edmondson)) (epidemiologist).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((john edmunds) OR (john edmund))) or (jonathan edmondson)) (epidemiologist)".
• Adding a wildcard symbol may retrieve word variants: ((((john edmunds) OR (john edmund))) or (jonathan edmondson)) (epidemiologist)*.
