Dr. Erica Todd

Erica received her PhD from James Cook University (Australia) and has broad interests inErica ecology, evolution and reproductive biology.

Her work in the Gemmell Lab applies transcriptome sequencing and comparative genomic approaches to explore the molecular basis of female to male sex reversal in sequentially hermaphroditic fishes, including the common New Zealand Spotty wrasse.

Her past research and current collaborative projects span population genetics, phytogeography and mating system biology, and include investigating how climatic, landscape and disease processes shape biodiversity in freshwater turtles and frogs.
