Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Enzyme
  • Ecology

André J. Simpson mostly deals with Nuclear magnetic resonance spectroscopy, Soil organic matter, Environmental chemistry, Analytical chemistry and Organic chemistry. His Magic angle spinning study in the realm of Nuclear magnetic resonance spectroscopy connects with subjects such as Environmental research. His Soil organic matter study introduces a deeper knowledge of Soil water.

His studies in Environmental chemistry integrate themes in fields like Organic matter, Toxicity, Earthworm, Eisenia fetida and Particulates. His biological study spans a wide range of topics, including Dissolved organic carbon, Phase and NMR spectra database. His research investigates the connection between Organic chemistry and topics such as Computational chemistry that intersect with issues in Humic acid.

His most cited work include:

  • Microbially derived inputs to soil organic matter: are current estimates too low? (290 citations)
  • Humic Substances in Soils: Are They Really Chemically Distinct? (259 citations)
  • Chemical and mineralogical controls on humic acid sorption to clay mineral surfaces (225 citations)

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

André J. Simpson mainly investigates Environmental chemistry, Nuclear magnetic resonance spectroscopy, Soil organic matter, Organic matter and Dissolved organic carbon. His Environmental chemistry research includes elements of Eisenia fetida, Sorption, Soil water, Biomass and Carbon. His Nuclear magnetic resonance spectroscopy research incorporates elements of Biological system, Molecule and Analytical chemistry.

His studies deal with areas such as Humus, Soil fertility and Botany as well as Soil organic matter. The various areas that André J. Simpson examines in his Organic matter study include Aliphatic compound, Total organic carbon and Aqueous solution. His Dissolved organic carbon research is multidisciplinary, incorporating elements of Aquatic ecosystem, Mineralogy and Alicyclic compound.

He most often published in these fields:

  • Environmental chemistry (41.32%)
  • Nuclear magnetic resonance spectroscopy (28.93%)
  • Soil organic matter (17.36%)

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

  • Biological system (7.85%)
  • Two-dimensional nuclear magnetic resonance spectroscopy (5.79%)
  • Metabolomics (13.64%)

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

His primary areas of study are Biological system, Two-dimensional nuclear magnetic resonance spectroscopy, Metabolomics, Nuclear magnetic resonance spectroscopy and Environmental chemistry. His research in Biological system intersects with topics in Flux, Aquatic organisms and Spinning. His work in the fields of Two-dimensional nuclear magnetic resonance spectroscopy, such as Heteronuclear single quantum coherence spectroscopy, intersects with other areas such as Allolobophora chlorotica.

In his research on the topic of Metabolomics, Relaxation and Magic angle spinning is strongly related with Proton NMR. In his work, Mineral, Soil water and Bond formation is strongly intertwined with Biomass, which is a subfield of Nuclear magnetic resonance spectroscopy. André J. Simpson is studying Dissolved organic carbon, which is a component of Environmental chemistry.

Between 2018 and 2021, his most popular works were:

  • Digital microfluidics and nuclear magnetic resonance spectroscopy for in situ diffusion measurements and reaction monitoring (18 citations)
  • A ubiquitous tire rubber–derived chemical induces acute mortality in coho salmon (16 citations)
  • Rapid Chemical Reaction Monitoring by Digital Microfluidics‐NMR: Proof of Principle Towards an Automated Synthetic Discovery Platform (12 citations)

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

  • Organic chemistry
  • Enzyme
  • Ecology

André J. Simpson focuses on Metabolite, Environmental chemistry, Heteronuclear single quantum coherence spectroscopy, Metabolome and Biochemistry. André J. Simpson focuses mostly in the field of Environmental chemistry, narrowing it down to topics relating to Daphnia magna and, in certain cases, Organic matter, Effluent, Wastewater, Ecotoxicology and Sterilization. The Heteronuclear single quantum coherence spectroscopy study combines topics in areas such as Flux, Biological system, Quantitative analysis and Water flea.

The study incorporates disciplines such as Amino acid, Dissolved organic carbon and Protein structure in addition to Metabolome. His study in Eisenia fetida extends to Biochemistry with its themes. His Metabolomics study integrates concerns from other disciplines, such as Perfluorooctane and Toxicity.
