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

  • Botany
  • Ecology
  • Photosynthesis

Barry A. Logan mainly investigates Environmental science, Evergreen, Horticulture, Photoprotection and Xanthophyll. His Horticulture study incorporates themes from Action spectrum, Photoinhibition, Photosystem II and Carotenoid. His work carried out in the field of Carotenoid brings together such families of science as Photosynthesis and Chlorophyll fluorescence.

His study on Photosynthetic capacity is often connected to Water transport as part of broader study in Photosynthesis. The various areas that Barry A. Logan examines in his Photoprotection study include Chlorophyll and Anthocyanin.
