Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Ecology
  • Botany

His primary areas of investigation include Ecology, Phytophthora infestans, Phytophthora ramorum, Oomycete and Phytophthora. His Ecology research incorporates themes from Disease management, Population genetics and Genetic diversity. His Phytophthora infestans study introduces a deeper knowledge of Blight.

His Oomycete study integrates concerns from other disciplines, such as Range, Genome, Lineage and Botany. In general Genome study, his work on Population genomics often relates to the realm of R package, thereby connecting several areas of interest. His studies deal with areas such as Genetics and Phylogenetics, Coalescent theory as well as Phytophthora.

His most cited work include:

  • Genome sequence and analysis of the Irish potato famine pathogen Phytophthora infestans. (1066 citations)
  • Poppr: an R package for genetic analysis of populations with clonal, partially clonal, and/or sexual reproduction. (1033 citations)
  • Phytophthora Genome Sequences Uncover Evolutionary Origins and Mechanisms of Pathogenesis (840 citations)

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

The scientist’s investigation covers issues in Botany, Genetics, Phytophthora infestans, Phytophthora and Phytophthora ramorum. His Botany research includes elements of Host and Ribosomal DNA. His Genetics study focuses mostly on Genome, Oomycete, Gene, Microsatellite and Phylogenetics.

Niklaus J. Grünwald has included themes like Solanum, Center of origin and Oospore in his Phytophthora infestans study. He interconnects Ecology, Quarantine, Lineage, Lineage and Genotype in the investigation of issues within Phytophthora ramorum. His Ecology study also includes

  • Genetic diversity which connect with Genetic variation,
  • Evolutionary biology most often made with reference to Population genetics.

He most often published in these fields:

  • Botany (25.93%)
  • Genetics (28.40%)
  • Phytophthora infestans (21.81%)

What were the highlights of his more recent work (between 2018-2021)?

  • Genetics (28.40%)
  • Genetic diversity (15.64%)
  • Phytophthora (20.99%)

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

Genetics, Genetic diversity, Phytophthora, Genotype and Oomycete are his primary areas of study. His work in the fields of Gene, Single-nucleotide polymorphism and Genome overlaps with other areas such as Barcode. His research in Genome intersects with topics in Ploidy, Lineage, Center of origin and Phytophthora infestans.

His work deals with themes such as Zoology and Evolutionary biology, which intersect with Genetic diversity. His Phytophthora research is multidisciplinary, relying on both Forest management, Agroforestry and Biosecurity. His work is dedicated to discovering how Population genetics, Population biology are connected with Ecology and other disciplines.

Between 2018 and 2021, his most popular works were:

  • Mitotic Recombination and Rapid Genome Evolution in the Invasive Forest Pathogen Phytophthora ramorum. (21 citations)
  • Mitotic Recombination and Rapid Genome Evolution in the Invasive Forest Pathogen Phytophthora ramorum. (21 citations)
  • Ecology and Evolution of the Sudden Oak Death Pathogen Phytophthora ramorum. (19 citations)

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

  • Gene
  • Ecology
  • Botany

His main research concerns Gene, Genome, Genetic diversity, Genetics and Pathogen. His research integrates issues of Host plants and Computational biology in his study of Genome. His work carried out in the field of Genetic diversity brings together such families of science as Zoology, Clade, Population genetics and Species complex.

His Genetics research is multidisciplinary, incorporating perspectives in Phytophthora fragariae and Race. His Pathogen research incorporates elements of Phytophthora ramorum, Sudden oak death, Phylogenetics and Larch. In Sudden oak death, Niklaus J. Grünwald works on issues like Ecology, which are connected to Gymnosperm, PEST analysis and Phytosanitary certification.
