My research mainly focuses on 1) the evolution of mating type locus (MAT) in fungi, with emphasis on Cryptococcus neoformans and its closely related species; 2) meiotic recombination during same-sex and opposite-sex mating in Cryptococcus neoformans, and 3) uniparental mitochondrial inheritance in Cryptococcus amylolentus and Cryptococcus neoformans, the mechanisms and the evolutionary consequences.
