Growing up, I enjoyed exploring caves. As a graduate student in the 1970s, I studied earth science (geology), and I remember being fascinated by the lunar samples brought to Earth by earlier NASA lunar missions that we were able to study.
This experience led to my interest in space science. Later on I became involved with biology, which added a new dimension to my research. This led to my later work on how the carbon cycle relates to Earth’s history and to astrobiology.
