Happy to share that a chapter of my PhD thesis is now officially published in Genetics! 🎉 Our study sheds new light on the genomic composition and epigenetic features of the Drosophila melanogaster B chromosome. I’m grateful to all collaborators and mentors who were part of this journey!

Comparative genomic analysis and epigenetic profiling of the Drosophila melanogaster B chromosome

Abstract. Supernumerary B chromosomes have been identified in hundreds of species across many different taxa, each with their own evolutionary history, uni

Excited to share our review on evolutionary genomics of meiotic drive! We discuss how these genetic elements “cheat” Mendelian inheritance, their underlying molecular mechanisms, and their broader impacts on genome evolution, including effects on genetic diversity, recombination, and sex chromosome.

The evolutionary genomics of meiotic drive

Abstract. Meiotic drivers are selfish genetic elements that gain transmission advantages by distorting equal, Mendelian segregation. For decades, biologist
