Human Biology changed my life - twice. Through the program I had the opportunity to visit Gombe Stream Research Center to study chimpanzees. After 6 months at Gombe, I decided that medicine wasn't all that interesting and became a professional biologist. Over the next 30 years, I pursued an academic career of teaching and research. In 2002, I returned to Gombe to revisit the forest that had meant so much to me. I was so struck by the loss of forest surrounding Gombe (due to human population expansion) and its effect on Gombe's chimpanzees that I decided to take action. Catherine's story continued.
