"Charles is not only a highly respected veteran of the life sciences community but the venture capital community as well," said Lip-Bu Tan, chairman and founder of Walden International. "We see significant investment opportunities in the Internet technology, communications and biotechnology sectors, and Charles' strong skill set will compliment that of the existing Walden International team as we pursue these prospects in the coming years."

"Investment opportunities in the life sciences and healthcare industries continue to grow," said Charles Hsu. "I am looking forward to drawing on my previous experience to help Walden International take advantage of these opportunities."

He has invested in or co-founded over 25 healthcare and life sciences companies, about half of which are publicly listed today.
