Andrew Pask heads the Evo-Devo-Repro group. His research uses comparative mammalian genetics to identify critical and conserved genes driving development, particularly of the craniofacial region and reproductive tract. His work in reproduction has uncovered novel roles for estrogen in male development and helped to define the impacts of environmental contaminants on male reproductive health. His comparative genetics work has led to the sequencing of several marsupial genomes, including that of the extinct Tasmanian Tiger. He uses genome wide, cross species comparisons to define regions of the genome targeted by evolution to drive diversity and adaptation.
