International Sisters High Altitude Research Expedition
Women are 40% of those who ski, hike, trek and climb. Less than 7% of high-altitude research focuses on them. We're changing that.
ISHARE is the world's first all-women's high-altitude medical expedition, reaching 7,246 m (23,773 ft) in Nepal, but the science is relevant below the summit. Altitude illness can strike as low as 2,500 m (8,000 ft), affecting visitors to destinations like Vail, Aspen, and Cusco. This research is important for all mountain visitors, not just elite climbers.
We are backed by an international advisory board of leading scientists and mountaineers, including a Nobel Laureate.
We're raising $500,000 to fund the expedition and its research. We have raised approximately $75,000 of the $500,000 needed.
Our hearts are with the people of Nepal as the nation mourns the tragic losses due to severe flooding in September 2026. The entire ISHARE team stands in solidarity with the families, friends, and communities affected, sending our deepest thoughts, prayers, and heartfelt condolences. During this difficult time, we stand with Nepal with profound empathy and support.
Eighteen investigators, seventeen projects, one shared physiological dataset collected on the way up the mountain.
An international board of climbers, physicians, and scientists advises the expedition, including high-altitude medicine pioneer Peter Hackett, MD.
One individual, foundation or company will stand behind the first all-women medical research expedition to the Himalaya.
