As she herself describe her research; I am also a Research Scientist at the Blue Marble Space Institute of Science. I am fascinated by all questions regarding the nature of life in the universe: How did life begin? How common is life? Are there universal laws of biological systems? My research focuses on the origin of life, combining techniques from theoretical physics, chemistry, and information science, to uncover how the first living systems might have arisen on a lifeless planet.
