Alan R. Harvey focuses on Neuroscience, Cell biology, Optic nerve, Retinal ganglion and Anatomy. His work on Superior colliculus and Hippocampus as part of general Neuroscience research is frequently linked to Diffusion Anisotropy and Tortuosity, thereby connecting diverse disciplines of science. His Cell biology study combines topics in areas such as Controlled release, Nanoparticle, Immunology and Vesicle.

His primary area of study in Optic nerve is in the field of Retinal ganglion cell. The concepts of his Retinal ganglion cell study are interwoven with issues in Axotomy, Ciliary neurotrophic factor and Pathology. Alan R. Harvey interconnects Astrocyte, Transplantation and Brainstem in the investigation of issues within Anatomy.
