Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • DNA
  • Virus

His main research concerns Virology, Sapovirus, Norovirus, Genotype and Capsid. His Virology research incorporates elements of Phylogenetics and Microbiology. His Phylogenetics study which covers Genome that intersects with Recombinant DNA.

His study in Norovirus is interdisciplinary in nature, drawing from both Molecular epidemiology and Rotavirus. His research in Genotype is mostly concerned with Genotyping. The study incorporates disciplines such as Molecular typing, Pathogen, Mink and Disease in addition to Outbreak.

His most cited work include:

  • Coexistence of Multiple Genotypes, Including Newly Identified Genotypes, in Outbreaks of Gastroenteritis Due to Norovirus in Japan (371 citations)
  • Phylogenetic analysis of the complete genome of 18 Norwalk-like viruses. (279 citations)
  • Detection of human sapovirus by real-time reverse transcription-polymerase chain reaction (194 citations)

What are the main themes of his work throughout his whole career to date?

His primary scientific interests are in Virology, Sapovirus, Genotype, Norovirus and Genetics. Tomoichiro Oka combines subjects such as Recombinant DNA and Microbiology with his study of Virology. His Sapovirus research includes themes of Pathogen, Feces, Viral replication, Caliciviridae Infections and Sequence analysis.

His biological study spans a wide range of topics, including Phylogenetics and Whole genome sequencing. Tomoichiro Oka focuses mostly in the field of Norovirus, narrowing it down to topics relating to Molecular epidemiology and, in certain cases, Caliciviridae. His research investigates the connection between Capsid and topics such as Molecular biology that intersect with problems in Reverse transcription polymerase chain reaction.

He most often published in these fields:

  • Virology (78.72%)
  • Sapovirus (54.61%)
  • Genotype (34.04%)

What were the highlights of his more recent work (between 2015-2021)?

  • Virology (78.72%)
  • Sapovirus (54.61%)
  • Genome (21.28%)

In recent papers he was focusing on the following fields of study:

His primary areas of study are Virology, Sapovirus, Genome, Genetics and Phylogenetic tree. His Virology research integrates issues from Strain, Recombination and Pathogenesis. Genotype and Norovirus are inextricably linked to his Sapovirus research.

His Genotype study combines topics in areas such as Reverse transcription polymerase chain reaction, Cysteine protease, Outbreak, Complementary DNA and Primer. His work deals with themes such as Feces and Sequence analysis, which intersect with Genome. Tomoichiro Oka interconnects Wild boar, Phylogenetics, Virus and Metagenomics in the investigation of issues within Phylogenetic tree.

Between 2015 and 2021, his most popular works were:

  • Genetic Characterization and Classification of Human and Animal Sapoviruses. (42 citations)
  • Genetic Characterization and Classification of Human and Animal Sapoviruses. (42 citations)
  • Attempts to grow human noroviruses, a sapovirus, and a bovine norovirus in vitro. (26 citations)

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

  • Gene
  • DNA
  • Virus

The scientist’s investigation covers issues in Sapovirus, Virology, Genetics, Genome and Polymerase chain reaction. His Sapovirus study improves the overall literature in Genotype. He has researched Genotype in several fields, including GenBank, Outbreak and Capsid.

Norovirus and Viral replication are the primary areas of interest in his Virology study. His Polymerase chain reaction research incorporates themes from Amino acid, Sequence analysis, NS3, Mink and Protein sequencing. The various areas that he examines in his Coding region study include Peptide sequence, Strain, Genetic diversity and Phylogenetics.
