In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Disease
  • Ecology

Richard Speare mostly deals with Public health, Strongyloidiasis, Chytridiomycosis, Socioeconomics and Strongyloides stercoralis. His Public health research is multidisciplinary, incorporating perspectives in Veterinary medicine, Action research and Environmental health. His Strongyloidiasis study which covers Pediatrics that intersects with Surgery, Ivermectin and Neglected tropical diseases.

Research on Amphibian and Ecology is a part of his Chytridiomycosis study. His Socioeconomics research incorporates elements of Ebola virus, Outbreak and Index case. His Strongyloides stercoralis research integrates issues from Socioeconomic status, Health care, CINAHL and Pathology.
