  • 2014 - Fellow of the Soil Science Society of America (SSSA)

Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Agriculture
  • Organic chemistry

Johannes Lehmann mainly investigates Biochar, Soil water, Agronomy, Slash-and-char and Soil organic matter. His Biochar research is multidisciplinary, incorporating perspectives in Biomass, Nutrient, Carbon sequestration and Charcoal. His research integrates issues of Environmental chemistry, Carbon, Carbon cycle and Hydrology in his study of Soil water.

His work deals with themes such as Soil management, Soil chemistry, Soil fertility and Leaching, which intersect with Agronomy. His Slash-and-char research focuses on Fertilizer and how it relates to Compost. His Soil organic matter research incorporates themes from Organic matter, Soil carbon and Humus.

His most cited work include:

  • GW170817: observation of gravitational waves from a binary neutron star inspiral (4913 citations)
  • Persistence of soil organic matter as an ecosystem property (2867 citations)
  • Biochar effects on soil biota – A review (2299 citations)

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

Johannes Lehmann spends much of his time researching Soil water, Biochar, Agronomy, Environmental chemistry and Soil organic matter. His Soil water research incorporates elements of Organic matter and Total organic carbon. His Biochar study incorporates themes from Biomass, Carbon sequestration and Charcoal.

His work investigates the relationship between Agronomy and topics such as Soil fertility that intersect with problems in Agroforestry. His study in Environmental chemistry is interdisciplinary in nature, drawing from both Carbon and Mineralogy. Johannes Lehmann combines subjects such as Ecosystem and Environmental protection with his study of Soil carbon.

He most often published in these fields:

  • Soil water (28.57%)
  • Biochar (25.22%)
  • Agronomy (25.40%)

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

  • LIGO (13.05%)
  • Gravitational wave (11.82%)
  • Soil water (28.57%)

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

His primary areas of study are LIGO, Gravitational wave, Soil water, Astrophysics and Environmental chemistry. His Soil water research is multidisciplinary, relying on both Agriculture and Nutrient. His work on Neutron star, Binary black hole and Redshift as part of general Astrophysics study is frequently connected to Dimensionless quantity and Coincident, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.

His Environmental chemistry research incorporates elements of Organic matter, Extraction, Nitrogen and Pyrolysis, Biochar. The concepts of his Organic matter study are interwoven with issues in Soil organic matter, Carbon and Biomass. His research in Biochar intersects with topics in Agronomy, Fertilizer, Straw and Manure.

Between 2018 and 2021, his most popular works were:

  • GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs (1290 citations)
  • Properties of the Binary Neutron Star Merger GW170817 (399 citations)
  • GW190425: Observation of a Compact Binary Coalescence with Total Mass $\sim 3.4 M_{\odot}$ (389 citations)

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

  • Ecology
  • Agriculture
  • Organic chemistry

His main research concerns LIGO, Astrophysics, Gravitational wave, Neutron star and Binary black hole. His study in LIGO is interdisciplinary in nature, drawing from both Cosmic string and Noise. His Astrophysics study often links to related topics such as Coalescence.

His Gravitational wave research focuses on Pulsar and how it connects with Moment of inertia, Luminosity and KAGRA. The Neutron star study combines topics in areas such as Mass ratio, Cosmology, Gamma-ray burst, Mass distribution and Spin-½. He focuses mostly in the field of Binary black hole, narrowing it down to topics relating to General relativity and, in certain cases, Dark matter.
