Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Genus

Khidir W. Hilu mostly deals with Phylogenetics, Evolutionary biology, Botany, Austrobaileyales and Basal angiosperms. His Phylogenetics study contributes to a more complete understanding of Genetics. His study in Evolutionary biology is interdisciplinary in nature, drawing from both Taxon, Taxonomic rank, Flowering plant and Macroevolution.

His Botany research is multidisciplinary, incorporating elements of Molecular phylogenetics, Commelinids and Corsiaceae, Liliales, Pandanales. The study incorporates disciplines such as Laurales and Nymphaeales in addition to Austrobaileyales. His Nymphaeales research includes elements of Santalales and Saxifragales.

His most cited work include:

  • Angiosperm phylogeny: 17 genes, 640 taxa (499 citations)
  • Angiosperm phylogeny based on matK sequence information (450 citations)
  • Noncoding plastid trnT-trnF sequences reveal a well resolved phylogeny of basal angiosperms (292 citations)

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

His primary areas of study are Botany, Phylogenetics, Genetics, Phylogenetic tree and Evolutionary biology. His Botany study combines topics in areas such as Chloridoideae and Monophyly. His work carried out in the field of Phylogenetics brings together such families of science as Nucleic acid sequence, Chromosome and DNA sequencing.

His study in the field of Gene, Pseudogene, Intron and Molecular evolution is also linked to topics like Group II intron. Khidir W. Hilu has researched Phylogenetic tree in several fields, including Genome evolution and Genome. His Evolutionary biology study integrates concerns from other disciplines, such as Taxon, Austrobaileyales, Basal angiosperms, Nymphaeales and Ranunculales.

He most often published in these fields:

  • Botany (56.52%)
  • Phylogenetics (30.43%)
  • Genetics (29.35%)

What were the highlights of his more recent work (between 2008-2019)?

  • Phylogenetics (30.43%)
  • Botany (56.52%)
  • Phylogenetic tree (19.57%)

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

The scientist’s investigation covers issues in Phylogenetics, Botany, Phylogenetic tree, Genetics and Molecular phylogenetics. His research integrates issues of Mutualism and Lichen in his study of Phylogenetics. His Botany study combines topics from a wide range of disciplines, such as Comparative anatomy and Clade.

His Phylogenetic tree research integrates issues from Evolutionary biology and Subfamily. When carried out as part of a general Genetics research project, his work on Plastid, Pseudogene and Intron is frequently linked to work in Eukaryotic translation and Group II intron, therefore connecting diverse disciplines of study. His research in Molecular phylogenetics intersects with topics in Caryophyllales, Rivina, Taxon, GenBank and Poaceae.

Between 2008 and 2019, his most popular works were:

  • Angiosperm phylogeny: 17 genes, 640 taxa (499 citations)
  • Land plant evolutionary timeline: Gene effects are secondary to fossil constraints in relaxed clock estimation of age and substitution rates (208 citations)
  • Phylogeny of the Caryophyllales Sensu Lato: Revisiting Hypotheses on Pollination Biology and Perianth Differentiation in the Core Caryophyllales (99 citations)

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

  • Gene
  • Botany
  • Genus

Khidir W. Hilu focuses on Ecology, Botany, Subfamily, Phylogenetics and Phylogenetic tree. His work on Mutualism and Lichen as part of general Ecology study is frequently linked to Leotiomyceta, Symbiosis and Ectosymbiosis, therefore connecting diverse disciplines of science. Specifically, his work in Botany is concerned with the study of Rhabdodendron.

His studies deal with areas such as Pappophorum, Polyphyly and Triticeae as well as Subfamily. His Phylogenetics research spans across into areas like Biome and Agaricomycetes. His work deals with themes such as Poeae, Pooideae and Tribe, which intersect with Phylogenetic tree.
