Current position

Senior lecturer with research, teaching and supervision responsibility.

Academic interests

I try to understand how animals evolved from their single-celled ancestors - one of the greatest events in evolution. I am leading a project where we study the significance of gene regulatory elements in the evolution of complex animal body plans from their single-celled ancestors. 

Other projects I am involved in focus on the evolution of cell morphologies in various protist groups, and the evolution and ecology of protists and their transition between different aquatic habitats. I have studied the species diversity of protist groups such as Radiolarians, Telonemia, Perkinsea, and Haptophytes.

Methods I am using include transcriptome and gene expression analyses, single-cell genome and transcriptome sequencing, environmental sequencing and phylogenetics.
