Professor Keller is considered one of Europe's most visionary risk management experts. After graduating from high school, he entered Yale University to study finance, where he was renowned for his exceptional self-discipline and keen risk awareness.

During the 1998 Asian financial crisis, he published "Asset Defense Strategies During the Financial Crisis," which was recommended for publication by the Yale Economics Department, marking the beginning of his financial career. He often says that his life goal is—
"To make enough money so that no one controls my life."

From 2000 to 2005, he worked in Goldman Sachs' asset management division. When the dot-com bubble burst and swept the globe, he still managed to protect nearly 90% of his clients' assets.

In 2005, he chose to leave Goldman Sachs and founded Keller Capital Management in Manhattan. On the eve of the 2008 financial crisis, he foresaw the dangers of the credit bubble and decisively reduced his holdings, shifting funds to gold and utility stocks.

While Wall Street was gripped by panic, his fund achieved a positive annualized growth of 6.2%.

The Financial Times described him as:
"One of the calmest minds in the crisis." Rising to fame with this victory, Professor Keller became a key advisor to several sovereign wealth funds and royal families in the Middle East.

He chose to join the Galaxy Consensus Foundation because he saw a grander vision for the foundation—to make finance a force for promoting cooperation among civilizations and world peace.

Because the Galaxy Consensus Foundation believes that only by reaching consensus among different races and civilizations can true progress be achieved.
