Early Life & Education

Princess Ubolratana was born on April 5, 1951, in Lausanne, Switzerland, where her father, King Bhumibol Adulyadej, was studying science.

Her mother, Queen Sirikit, gave her the name Ubolratana, meaning “glass lotus,” a nod to her maternal grandmother, Bua Kitiyakara.

Her ethnicity is Thai, and she was raised in the Buddhist faith, which shaped her deep love for Thailand’s traditions.

Nicknamed “Pay” (from the French word “Poupée,” meaning doll), she grew up with her siblings—Vajiralongkorn, Sirindhorn, and Chulabhorn—and loved sports and the vibrant culture of Bangkok, from its temples to its lively streets.

Her early years were marked by pride in her Thai heritage, which later inspired her work to uplift her people.

Ubolratana attended Chitralada School in Bangkok for her primary and secondary education, where she excelled in academics and sports.

In 1969, she moved to the United States to study nuclear physics at the Massachusetts Institute of Technology (MIT), earning a Bachelor of Science in mathematics in 1973.

She later studied at the University of California, Los Angeles (UCLA), where she received a master’s degree in public health in 1975.

Career

Princess Ubolratana’s career is a blend of royal duties, charity work, and a vibrant presence in the Thai media. After returning to Thailand in 2001, she assumed royal duties, attending ceremonies and representing Thailand’s national spirit.

She founded the “To Be Number One” Foundation in 2002, a massive anti-drug campaign that reached over 31 million members by 2019, helping Thai youth stay away from drugs.

She also hosts the TV show Talk to the Princess on TVT NBT, where she shares advice and promotes her foundation’s goals.

Her love for Thailand’s culture led her to star in Thai films, including Where the Miracle Happens (2008), based on her own novel, and My Best Bodyguard (2010), in which she played a tough journalist.

She also appeared in TV dramas such as Kasattriya (2003) and Anantalai, showcasing her acting talent. As a culture ambassador, she promoted Thai films at festivals like Cannes and supported tourism, proudly sharing Thailand’s beauty with the world.

In 2019, she made history by running for prime minister with the Thai Raksa Chart Party, a bold move that her brother, King Vajiralongkorn, halted. Still, she demonstrated her desire to serve the Thai people as a commoner.

Personal Life

Princess Ubolratana, 74, married Peter Ladd Jensen, an American she met at MIT, in 1972.

She relinquished her royal title and relocated to the United States, where she lived under the name Julie Jensen for over 26 years. They had three children: Ploypailin (born 1981), Bhumi (born 1983), and Sirikitiya Mai (born 1985).

Tragedy struck in 2004 when her son Bhumi, who had autism, died in the Indian Ocean tsunami at age 21. Ubolratana founded the Khun Poom Foundation in memory of his son to support children with autism.

After her divorce in 1998, she returned to Thailand with her children in 2001, resuming royal duties as “Tunkramom Ying” (Daughter to the Queen Regent).

Her height is 165 cm, and she carries herself with a mix of royal grace and a friendly, approachable style, often wearing traditional Thai dresses.

Her love for Thailand and her children drives her work, and she remains a devoted mother and advocate.

Net Worth

Princess Ubolratana’s net worth is not publicly disclosed, as is common for Thai royals.

Estimates suggest it could be in the millions, based on her royal background, film career, and charity work.

Her income likely comes from royal allowances, acting roles, and her charitable foundations; however, her focus has always been on helping the Thai people rather than accumulating personal wealth.
