Philippa Helen Gander ONZM is a New Zealand sleep researcher. In 2021, she was conferred with the title of emeritus professor by Massey University, where she had been inaugural director of the Sleep/Wake Research Centre until stepping down from that role in 2019.^[1]

Gander wrote her master's thesis at the University of Auckland in 1976 with the title A model for the circadian pacemaker of Hemideina thoracica derived from the effects of temperature on its activity rhythm.^[2] After a 1980 PhD titled Circadian organization in the regulation of locomotor activity and reproduction in Rattus exulans at the same institution,^[3] Gander took up a Fulbright Fellowship at Harvard Medical School in 1980. She moved to the NASA-Ames Research Center in 1983 as part of the flight crew fatigue and jet-lag research programme. Gander returned to New Zealand in 1998, and established the Sleep/Wake Research Centre at the Wellington School of Medicine with the assistance of funding from the Health Research Council of New Zealand. She moved to Massey University and was appointed a full professor in 2003, and the research centre became part of Massey's newly established research school of public health.^{[1][4][5][6][7][8][9][10]}

In 2009, Gander was elected a Fellow of the Royal Society of New Zealand.^[11] In the 2017 Queen's Birthday Honours, she was appointed an Officer of the New Zealand Order of Merit, for services to the study of sleep and fatigue.^[12]
