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

  • Gene
  • Genetics
  • Botany

Quantitative trait locus, Genetics, Agronomy, Genetic marker and Single-nucleotide polymorphism are his primary areas of study. His Quantitative trait locus research integrates issues from Association mapping, Biotechnology, Linkage disequilibrium and Plant breeding. His Agronomy research is multidisciplinary, incorporating perspectives in Genetic gain and Introgression.
