Midwife and specialist in men's & women's hormone therapy (IOBIM), with a focus on systems-based physiology.
Since 2002, her work has centred on women's health and nutrition. Over time, this evolved into a broader systems approach to care that integrates hormones, metabolism, nutrition, sleep, stress physiology, and environmental inputs into individualized physiological care.
