My name is Ci Fu, and I am from China. I obtained my Doctorate degree in Dr. Stephen J Free’s laboratory. My thesis work focused on cell-to-cell fusion in Neurspora crassa. I carried out a genome-wide gene deletion mutant screen and identified novel genes that are required for cell-to-cell fusion. And I further characterized three of the novel genes, ham-6, ham-7 and ham-8, function upstream of MAK-1 MAP (mitogen activated protein) kinase pathway during cell-to-cell fusion. Besides my thesis project, I have also worked on characterization of genes that are involved in cell wall biosynthesis pathway.

My research focuses on the elucidation of the mating mechanisms in the Cryptococcus neoformans species complex. Specifically, I am interested in: 1) the endoreplication pathway that regulates ploidy duplication during unisexual reproduction; 2) karyogamy machinery differences that drive distinct karyogamy events during bisexual reproduction between C. neoformans and C. deneoformans; 3) the calcineurin pathway that regulates morphogenesis during unisexual reproduction.
