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

  • Ecology
  • Agriculture
  • Agronomy

His main research concerns Bacillus thuringiensis, PEST analysis, Genetically modified maize, Fall armyworm and Bioassay. You can notice a mix of various disciplines of study, such as Genetically modified crops, Pupa, Environmental planning and Integrated pest management, in his Bacillus thuringiensis studies. His study explores the link between PEST analysis and topics such as Insect that cross with problems in Midgut, Receptor and Biochemistry.

His Genetically modified maize research includes themes of Helicoverpa zea, Larva and Agronomy. His Agronomy and Sowing and Resistance investigations all form part of his Agronomy research activities. His study looks at the relationship between Bioassay and fields such as Horticulture, as well as how they intersect with chemical problems.
