Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Agronomy
  • Ecology

The scientist’s investigation covers issues in Agronomy, Crop, Climate change, Crop yield and Simulation modeling. His work on Agronomy is being expanded to include thematically relevant topics such as Arid. His work focuses on many connections between Crop and other disciplines, such as Canopy, that overlap with his field of interest in Chlorophyll.

The study incorporates disciplines such as Climatology, Grain quality and Yield in addition to Climate change. His research integrates issues of Global warming and Agriculture in his study of Yield. His research investigates the connection between Crop yield and topics such as Hydrology that intersect with problems in Calibration, Ensemble forecasting, Estimator and Statistics.

His most cited work include:

  • Rising Temperatures Reduce Global Wheat Production (801 citations)
  • Uncertainty in Simulating Wheat Yields Under Climate Change (749 citations)
  • Multimodel ensembles of wheat growth: many models are better than one (254 citations)

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

His scientific interests lie mostly in Agronomy, Crop, Climate change, Soil water and Water use. His research in Sowing, Cultivar, Tillage, Phenology and Anthesis are components of Agronomy. His work carried out in the field of Crop brings together such families of science as Growing season, Biomass, Canopy, Plant breeding and Yield.

He integrates many fields in his works, including Climate change and Simulation modeling. His research integrates issues of Pasture, Water-use efficiency, Stomatal conductance, Crop rotation and Soil horizon in his study of Water use. Garry O'Leary has included themes like Global warming, Climatology, Crop yield and Atmospheric sciences in his Yield study.

He most often published in these fields:

  • Agronomy (69.92%)
  • Crop (28.46%)
  • Climate change (24.39%)

What were the highlights of his more recent work (between 2015-2021)?

  • Agronomy (69.92%)
  • Climate change (24.39%)
  • Crop (28.46%)

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

His main research concerns Agronomy, Climate change, Crop, Cultivar and Cropping. His study in Anthesis, Water use, Phenology, Water-use efficiency and Growing season are all subfields of Agronomy. In his works, Garry O'Leary performs multidisciplinary study on Growing season and Simulation modeling.

The study incorporates disciplines such as Yield, Agriculture, Agricultural productivity, Atmospheric sciences and Crop yield in addition to Climate change. His Crop study combines topics from a wide range of disciplines, such as Canola, Biomass, Soil nitrogen, Frost and Yield. The Cultivar study combines topics in areas such as Arid, Grain yield, Irrigation and Sowing.

Between 2015 and 2021, his most popular works were:

  • Similar estimates of temperature impacts on global wheat yield by three independent methods (180 citations)
  • The uncertainty of crop yield projections is reduced by improved temperature response functions. (99 citations)
  • Climate change impact and adaptation for wheat protein (97 citations)

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

  • Agriculture
  • Ecology
  • Agronomy

His primary scientific interests are in Climate change, Agronomy, Simulation modeling, Yield and Agriculture. Garry O'Leary has researched Climate change in several fields, including Cropping, Crop yield, Food security and Hydrology. His work in Agronomy is not limited to one particular discipline; it also encompasses Transpiration.

Garry O'Leary interconnects Natural resource and Futures studies in the investigation of issues within Agriculture. In his research, Atmospheric sciences is intimately related to Soil water, which falls under the overarching field of Water use. The various areas that Garry O'Leary examines in his Crop study include Cultivar, Vapour Pressure Deficit and Phenology.
