Sonam Wangchuk is an Indian mechanical engineer, education reformer, innovator, and environmental activist from Ladakh, best known as the founder of the Students’ Educational and Cultural Movement of Ladakh (SECMOL) and the inventor of the “Ice Stupa” artificial glacier technique.
His life inspired the character Phunsukh Wangdu in the 2009 Bollywood film “3 Idiots,” and in 2025 he became a central figure in protests over statehood and constitutional protections for Ladakh.

Early Life
Sonam Wangchuk was born on September 1, 1966, near Alchi in the Leh district of what was then the Indian state of Jammu and Kashmir (now the union territory of Ladakh).
He was not enrolled in school until age nine, as there were no schools in his village, and his mother taught him in his native Ladakhi language until then.
In 1975, when his father, Sonam Wangyal, was elected to the Jammu and Kashmir government, the family moved to Srinagar, where Wangchuk was enrolled in school and struggled due to the unfamiliar language of instruction.
He later described this as the darkest period of his life. In 1977, he fled alone to Delhi, where he successfully pleaded his case to a Kendriya Vidyalaya principal for admission.
Education
Wangchuk completed a Bachelor of Technology in Mechanical Engineering from the National Institute of Technology, Srinagar, in 1987, financing his own education after differences with his father over his choice of engineering stream.
In 2011, he pursued two years of further study in earthen architecture at the École d’Architecture in Grenoble, France.
Career
In 1988, after graduating, Wangchuk, together with his brother and five peers, founded the Students’ Educational and Cultural Movement of Ladakh (SECMOL), aimed at reforming an education system in Ladakh that was poorly suited to local language, culture, and geography. He designed the SECMOL campus near Leh to run entirely on solar energy, using no fossil fuels for cooking, lighting, or heating. He was instrumental in launching “Operation New Hope” in 1994, a collaboration between government, village communities, and civil society to reform government schools, which helped raise pass rates in Ladakhi schools from around 5 percent to more than 50 percent.
From June 1993 to August 2005, Wangchuk edited Ladakh’s only print magazine, “Ladags Melong.” In 2001, he was appointed an education advisor to the Hill Council government, and in 2002 he co-founded the Ladakh Voluntary Network, serving as its secretary until 2005. He was appointed to the National Governing Council for Elementary Education under India’s Ministry of Human Resource Development in 2005, and worked as an education advisor for the Danish NGO MS from 2007 to 2010.
In late 2013, Wangchuk invented and built a prototype of the “Ice Stupa,” an artificial glacier that stores wasted winter stream water in the form of large conical ice heaps, releasing it in spring when farmers need it most. The innovation, which addresses water scarcity linked to melting Himalayan glaciers, has since been replicated in Switzerland and other mountain regions. He later founded the Himalayan Institute of Alternatives, Ladakh (HIAL) with his wife, Gitanjali J. Angmo, aiming to provide higher education and sustainable development solutions tailored to Ladakh’s unique environment.
Wangchuk’s life and educational philosophy inspired the character of Phunsukh Wangdu, played by Aamir Khan, in the 2009 Bollywood blockbuster “3 Idiots,” which brought him national and international recognition. In September 2025, Wangchuk became a leading voice in protests in Leh demanding statehood and Sixth Schedule constitutional protections for Ladakh. Following clashes between demonstrators and security forces on September 24, 2025, in which four people died and dozens were injured, authorities described Wangchuk as a “chief provocateur” and detained him under India’s National Security Act (NSA) on September 26, 2025, transferring him to a prison in Jodhpur, Rajasthan. His wife filed a habeas corpus petition challenging the detention before the Supreme Court of India. On March 14, 2026, the Union government revoked Wangchuk’s NSA detention after nearly six months, citing the need to restore dialogue and stability in Ladakh.
