研究领域

Dr Helfer’s main interests and areas of expertise are in neuroendocrinology and chronobiology. Her research so far has centred on the control of circadian rhythms and seasonality in vertebrates and this has recently led to investigations in the central regulation of growth and energy balance

neuroendocrinology, biological clocks, photoperiod, obesity, energy balance, metabolism, neuroinflammation, hypothalamic plasticity
