Research Interests

Wheat Genetics and Genomics

The main thrust of research in my laboratory is the development of genome sequencing technologies for plant genomes and their deployment in sequencing of large genomes in the tribe Triticeae, focusing on wheat. The knowledge is employed in addressing some fundamental questions of plant genome evolution, such as the meaning of genome size variation, gene distribution along chromosomes, and role of recombination in the evolution of genome structure. I also conduct research on genetics of homoeologous chromosome pairing in polyploid plants and the use of wild wheat in wheat improvement.
