His scientific interests lie mostly in Genetics, Molecular biology, Mutation, DNA and Polymerase chain reaction. In the subject of general Genetics, his work in Phenotype and Epigenetics is often linked to Gene dosage, NLRP7 and Genomic imprinting, thereby combining diverse domains of study. Within one scientific family, he focuses on topics pertaining to Digital polymerase chain reaction under Molecular biology, and may sometimes address concerns connected to TaqMan, Polymerase chain reaction optimization and Variants of PCR.

Graham R. Taylor has included themes like Optic nerve hypoplasia, Histone acetyltransferase, Lissencephaly and Cell biology in his Mutation study. Graham R. Taylor works mostly in the field of DNA, limiting it down to topics relating to Gene and, in certain cases, Immunohistochemistry, Rectum, Cancer research and Wallerian degeneration, as a part of the same area of interest. His Polymerase chain reaction research incorporates themes from RNA, Helicobacter pylori and 16S ribosomal RNA.
