A/Prof. Robin Hobbs established his lab at the Australian Regenerative Medicine Institute, Monash University in 2012 before joining the Hudson Institute as Associate Professor in 2020. His laboratory is focused on defining molecular mechanisms regulating spermatogonial stem cell (SSC) function and male fertility using the mouse as a model. His interest in the stem cell field was developed during PhD studies in the United Kingdom with Fiona Watt, an internationally recognized expert in the epidermal stem cell field. During postdoctoral studies in the United States at the Memorial Sloan-Kettering Cancer Center and Beth Israel Deaconess Medical Center, he characterized a key role for the transcription factor PLZF in SSC self-renewal and fertility. Robin’s research group has subsequently characterised cellular heterogeneity and dynamics within the undifferentiated spermatogonial population using single cell approaches and defined multiple regulatory pathways essential for SSC function. Recent studies from his group have focused on understanding the regenerative capabilities of SSCs following germline damage induced by chemotherapy.
