What is he best known for?

The fields of study he is best known for:

  • Gene
  • Genetics
  • Internal medicine

Genome-wide association study, Genetics, Single-nucleotide polymorphism, Genotyping and Case-control study are his primary areas of study. He interconnects Allele, Genetic association, Locus, Type 2 diabetes and Candidate gene in the investigation of issues within Genome-wide association study. His research ties Glucose homeostasis and Genetics together.

He has included themes like Genetic architecture and Heritability in his Single-nucleotide polymorphism study.

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

Gudmar Thorleifsson spends much of his time researching Genetics, Allele, Genome-wide association study, Genetic architecture and Body fat distribution. His work on Proband, Nature versus nurture and Genotype as part of general Genetics research is frequently linked to Affect and Educational attainment, thereby connecting diverse disciplines of science. His Genome-wide association study study incorporates themes from Disease and Cardiology.

His Genetic architecture research incorporates elements of Bioelectrical impedance analysis, Bioinformatics, Lean body mass, Locus and Single-nucleotide polymorphism. His Bioinformatics research is multidisciplinary, incorporating perspectives in Body mass index and Linkage disequilibrium. Gudmar Thorleifsson focuses mostly in the field of Body fat distribution, narrowing it down to matters related to Hyperlipidemia and, in some cases, Type 2 diabetes.

Between 2017 and 2019, his most popular works were:

  • The nature of nurture: Effects of parental genotypes. (351 citations)
  • Multiancestry association study identifies new asthma risk loci that colocalize with immune-cell enhancer marks (203 citations)
  • Refining the accuracy of validated target identification through coding variant fine-mapping in type 2 diabetes (165 citations)

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

  • Gene
  • Genetics
  • Internal medicine

His primary areas of investigation include Genome-wide association study, Allele, Insulin resistance, Genetic association and Genetic architecture. His Genome-wide association study study typically links adjacent topics like Immunology. His work carried out in the field of Allele brings together such families of science as Adipocyte, Internal medicine, Endocrinology and Lipogenesis.

His Insulin resistance research integrates issues from Linkage disequilibrium and Bioinformatics. His Genetic association research is multidisciplinary, incorporating elements of Pleiotropy, Autoimmune disease, Immune system and Hay fever, Asthma. In his work, Genetics is strongly intertwined with Computational biology, which is a subfield of Genetic architecture.
