Greg Anderson initially completed a Bachelor of Agricultural Science (Honours) degree at Lincoln University, Canterbury, before deciding to focus on neuroendocrine control of fertility. During his PhD studies at Lincoln University and subsequent postdoctoral fellowships at West Virginia University and Massey University he investigated the central mechanisms underpinning seasonal control of fertility in sheep and red deer.
Leading his own research group at the University of Otago since 2004, Greg developed a research programme addressing how metabolic factors such as leptin act in the brain to regulate reproductive function. He has been a leader in elucidating the neurobiology of RFRP-3 since it was first shown to modulate reproduction in mammals. He has published over 45 research papers and has an H-index of 22.
