Dr. Francis Collins is a world renowned expert in human genetics who spearheaded the U.S. government's efforts to sequence the entire human genome at the National Institutes of Health. He is also arguably the most vocal Christian biologist of modern times. He recently wrote a book titled "The Language of God: A Scientist Presents Evidence for Belief", in which he explains his belief that science (i.e. evolution) and Judeo-Christian faith do not contradict.
