Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Fungus

The scientist’s investigation covers issues in Spore, Botany, Microbiology, Food science and Penicillium. His Spore research incorporates themes from Ecology, Pollutant, Immunology, Germination and Agricultural crops. His Alternaria alternata, Hay and Numerical taxonomy study in the realm of Botany connects with subjects such as Jaccard index and Actinomadura malachitica.

His Microbiology study integrates concerns from other disciplines, such as Microorganism, Actinomadura, Environmental chemistry and Allergy. His research investigates the connection with Food science and areas like Agar which intersect with concerns in Incubation, Yeast, Yeast extract and Agar plate. His studies in Penicillium integrate themes in fields like Fusarium culmorum and Aspergillus.

His most cited work include:

  • Bioaerosols and occupational lung disease (293 citations)
  • Fungal and actinomycete spores as pollutants of the workplace and occupational allergens. (235 citations)
  • Effect of temperature and pH on water relations of field and storage fungi (173 citations)

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

John Lacey focuses on Botany, Spore, Microbiology, Food science and Agronomy. His work on Penicillium and Aspergillus as part of his general Botany study is frequently connected to Water activity, thereby bridging the divide between different branches of science. John Lacey combines subjects such as Ecology and Germination with his study of Spore.

His Microbiology study frequently draws connections to adjacent fields such as Microorganism. His Food science research includes themes of Hay and Agar. His Aflatoxin study incorporates themes from Ochratoxin A and Horticulture.

He most often published in these fields:

  • Botany (21.31%)
  • Spore (18.03%)
  • Microbiology (14.75%)

What were the highlights of his more recent work (between 1992-2018)?

  • Aspergillus flavus (9.02%)
  • Aflatoxin (10.25%)
  • Mycotoxin (11.48%)

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

John Lacey spends much of his time researching Aspergillus flavus, Aflatoxin, Mycotoxin, Aerobiology and Botany. As part of his Food science and Microbiology and Aspergillus flavus studies, John Lacey is studying Aspergillus flavus. As part of the same scientific family, John Lacey usually focuses on Aflatoxin, concentrating on Horticulture and intersecting with Cladosporium.

Within one scientific family, John Lacey focuses on topics pertaining to Agronomy under Mycotoxin, and may sometimes address concerns connected to Respiration and Contamination. His study on Botany is intertwined with other disciplines of science such as Water activity and Cinnamon Oil. His work carried out in the field of Fungi imperfecti brings together such families of science as Penicillium and Spore.

Between 1992 and 2018, his most popular works were:

  • Bioaerosols and occupational lung disease (293 citations)
  • Analysis of the relationships between environmental factors (aeroallergens air pollution and weather) and asthma emergency admissions to a hospital in Mexico City (135 citations)
  • Effects of infection time and moisture on development of ear blight and deoxynivalenol production by Fusarium spp. in wheat (108 citations)

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

  • Botany
  • Ecology
  • Fungus

His primary areas of study are Spore, Aspergillus flavus, Microbiology, Fungi imperfecti and Botany. His Spore research includes elements of Veterinary medicine and Ecology. His Aspergillus flavus research is multidisciplinary, relying on both Penicillium verrucosum and Aflatoxin.

John Lacey works mostly in the field of Microbiology, limiting it down to concerns involving Incubation and, occasionally, Toxin, Yeast and Agar plate. The concepts of his Fungi imperfecti study are interwoven with issues in Fusarium, Horticulture and Penicillium. John Lacey performs integrative Botany and Water activity research in his work.
