Professor Kate Loveland from the Testis Development and Male Germ Cell Biology Research Group at Hudson Institute

Professor Kate Loveland, Senior Principal Research Fellow

Professor Loveland received her undergraduate and PhD degrees at Duke University in the United States, studying the molecular basis of mammalian fertilization. Her laboratory investigates the molecular and cellular mechanisms that underpin mammalian testis development and sperm production. The team’s objective is to identify and characterise the molecular switches that regulate cell fate decisions in sperm precursor cells (germ cells) and in the somatic cells that support them.  Specific research focus areas are: Signalling by activin/ TGFβ superfamily, Wnt and Hedgehog pathways, growth factor/hormone signalling cross-talk, and the contribution of regulated nuclear transport molecules to cellular development and stress responses.

She is a National Health and Medical Research Council of Australia Senior Research Fellow (since 2000) and is a Fellow of the Society for the Study of Reproduction. She received the American Society for Andrology Young Andrologist Award in 2004 and the Monash University Vice Chancellor’s Award for Excellence in Postgraduate Supervision in 2010. In 2014 she was granted an Honorary Liebig Professorship from the Justus-Liebig University in Giessen, Germany for her joint role in leading the establishment of an International PhD Research Training Group in the Pathogenesis of Male Reproduction (2013-ongoing).  In May 2018, Professor Loveland was awarded the Society for the Study of Reproduction (SSR) Fuller W Bazer International Scientist Award, which recognises an outstanding international scientist who has demonstrated excellence in research and graduate education at an institution outside of North America, and who demonstrates outstanding potential for leading and directing scientific research overseas.

Prof Loveland’s professional roles for her discipline include Society for Reproductive Biology: Program Chair, and Treasurer; American Society for Andrology: Annual Meeting Program co-Chair (2010), Founder and Chair of the Basic Science Workshop, President of Women in Andrology and Council member; Society for the Study of Reproduction: International Members Subcommittee Chair, Director, and Annual Meeting Program co-Chair (2017).

Prof Loveland has published over 130 peer-reviewed manuscripts, and she is currently serving as an Associate Editor for Andrology.
