Martin Andreas Nowak is an Austrian-born mathematical biologist and the author of several books. 

Nowak studied at the Albertus Magnus Gymnasium in Vienna. He attended the University of Vienna, and earned his Ph.D. in biochemistry and mathematics in 1989, working with Peter Schuster on quasi-species theory and with Karl Sigmund on evolution of cooperation. He received the highest Austrian honors (Sub auspiciis Praesidentis) when awarded his degree.

Nowak was co-director with Sarah Coakley of the Evolution and Theology of Cooperation project at Harvard University, sponsored by the Templeton Foundation. He is also a member of the Board of Advisers of the Templeton Foundation. In a lecture given at Harvard in March 2007 called “Evolution and Christianity”, Nowak, a Roman Catholic, argued that “Science and religion are two essential components in the search for truth. Denying either is a barren approach.”
