Facebook has just announced that University of California, San Francisco (UCSF) Chancellor Susan Desmond-Hellmann has joined its board of directors.

Desmond-Hellmann is the second woman to join the board in the past year, after Facebook COO Sheryl Sandberg became the first woman to join back in June 2012.

According to Facebook, Desmond-Hellmann “oversees all aspects of the university and medical center’s strategy and operations. She previously served as president, product development at the biotechnology pioneer, Genentech. In this role, she was responsible for Genentech’s pre-clinical and clinical development, process research and development, business development and product portfolio management. During her 14 years with the company, Desmond-Hellmann brought numerous cutting-edge cancer medicines to market to help people battle the disease.”

Desmond Hellman, and M.D., also has a Masters in public health. She also serves on Procter & Gamble’s board.

“I’ve always been drawn to organizations that do ground-breaking work,” said Desmond-Hellmann. “Facebook has an ambitious mission and long-term vision of innovation that is transforming how people connect with one another. I’m proud to be part of a company that is serving such an important purpose in the world.”

Before Facebook added Sheryl Sandberg to the board, the company faced pressure from activists who said that Facebook’s all-male board was unacceptable in this day and age.
