Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Cancer
  • Ecology

His primary scientific interests are in Agronomy, Poaceae, Cultivar, Ozone and Crop yield. His study in Tiller, Crop, Panicle, Dry matter and Growing season falls under the purview of Agronomy. His work carried out in the field of Poaceae brings together such families of science as Photosynthesis, Phytotoxicity and Fumigation.

Kazuhiko Kobayashi combines subjects such as Carbon dioxide, Animal science and Chlorophyll a with his study of Photosynthesis. In his work, Winter wheat, Field conditions, Ozone concentration and Pollution is strongly intertwined with Yield, which is a subfield of Cultivar. His work on Tropospheric ozone as part of general Ozone research is frequently linked to East Asia, thereby connecting diverse disciplines of science.

His most cited work include:

  • Comparing Simulated and Measured Values Using Mean Squared Deviation and its Components (417 citations)
  • Updated overall survival results from a randomized phase III trial comparing gefitinib with carboplatin–paclitaxel for chemo-naïve non-small cell lung cancer with sensitive EGFR gene mutations (NEJ002) (344 citations)
  • Impact of elevated ozone concentration on growth, physiology, and yield of wheat (Triticum aestivum L.): a meta‐analysis (271 citations)

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

Agronomy, Internal medicine, Ozone, Oncology and Paddy field are his primary areas of study. Kazuhiko Kobayashi interconnects Photosynthesis, Carbon dioxide and Biomass in the investigation of issues within Agronomy. His Internal medicine study combines topics from a wide range of disciplines, such as Gastroenterology and Surgery.

His Ozone study incorporates themes from Atmospheric sciences, Pollutant and Stomatal conductance. His study in Paddy field is interdisciplinary in nature, drawing from both Methane and Growing season. His studies in Poaceae integrate themes in fields like Panicle and Crop yield.

He most often published in these fields:

  • Agronomy (31.40%)
  • Internal medicine (21.84%)
  • Ozone (15.70%)

What were the highlights of his more recent work (between 2017-2021)?

  • Internal medicine (21.84%)
  • Agronomy (31.40%)
  • Oncology (11.60%)

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

His primary areas of investigation include Internal medicine, Agronomy, Oncology, Ozone and Climate change. His Lung cancer, Phases of clinical research, Normal control and Predictive marker study, which is part of a larger body of work in Internal medicine, is frequently linked to Lower urinary tract symptoms, bridging the gap between disciplines. His studies deal with areas such as Rice farming and Organic farming as well as Agronomy.

His Ozone study integrates concerns from other disciplines, such as Pollutant, Atmospheric sciences, Stomatal conductance, Crop yield and Vegetation. His biological study spans a wide range of topics, including Flux, Cultivar and Cell wall. He has included themes like Agriculture, Tropospheric ozone and Yield in his Climate change study.

Between 2017 and 2021, his most popular works were:

  • Tropospheric Ozone Assessment Report: Present-day tropospheric ozone distribution and trends relevant to vegetation (112 citations)
  • Carbon dioxide (CO2) levels this century will alter the protein, micronutrients, and vitamin content of rice grains with potential health consequences for the poorest rice-dependent countries. (104 citations)
  • Tropospheric ozone assessment report: Global ozone metrics for climate change, human health, and crop/ecosystem research (96 citations)

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

  • Internal medicine
  • Cancer
  • Ecology

His scientific interests lie mostly in Ozone, Agronomy, Climate change, Stomatal conductance and Tropospheric ozone. His Ozone study combines topics in areas such as Crop yield, Atmospheric sciences, Pollutant and Prunus. His Agronomy research integrates issues from Human nutrition and Agricultural chemistry.

His Stomatal conductance research incorporates elements of Flux, Cell wall and Yield. His Tropospheric ozone research incorporates themes from Vegetation and Food security. Kazuhiko Kobayashi focuses mostly in the field of Cultivar, narrowing it down to topics relating to Photosynthesis and, in certain cases, Apoplast and Horticulture.
