Guides
ISHARE is proud to present three highly accomplished mountain guides who will lead the expedition.
Anne-Aylin Sigg, MD
Lead Guide
Dr. Sigg, based in Zurich, Switzerland, is certified by the International Federation of Mountain Guides (IFMGA). She currently serves as co-president of the Swiss Society of Mountain Medicine and has a particular love of ice climbing, although skiing and rock climbing run a close second. In addition to being our lead guide, Dr. Sigg is an internist, intensive care physician and high-altitude researcher. She is a lead investigator on the ISHARE microcirculation study.
Adele Pennington, PhD
Climbing Guide
Dr. Pennington originally was a research biochemist but has been a full-time mountaineer and Mountaineering Instructor for over 35 years. Still living and working in the Highlands of Scotland, she has also climbed and guided mountains extensively around the world, including six 8000m peaks in the Himalayas, notably Everest twice.
Uta Ibrahimi
Climbing Guide
Uta Ibrahimi is a Kosovar mountaineer, UIMLA mountain leader and UIAA mountain guide, and social entrepreneur with extensive Himalayan expedition experience. In 2017, she became the first person from Kosovo to summit Mount Everest, and in 2025, she became the 14th woman in the world to complete all 14 peaks above 8,000 meters. She has guided expeditions to Everest and Aconcagua and is the founder of the Utalaya Foundation, which works with youth and girls through outdoor education.
Eighteen invited investigators, seventeen projects, forming an alliance to study women in the mountains.
An international board of climbers, physicians, and scientists advises the expedition, including Rita Christen, the first female president of the Swiss Mountain Guides Association.
