Wen Xuejun's budding dream in the United States blossomed in China.

After staying in the US for 16 years, and holding an endowed chair professorship at Virginia Commonwealth University, Wen returned to China and set up Ryan Nanomedicine Co Ltd in Suzhou, East China's Jiangsu province.

"I have an ambition to transfer my achievements in the lab into useful medical products, and I chose to realize this ambition in China, after careful consideration," said Wen, who now serves as the company's president.
