Jerry Coyne is a professor in the department of ecology and evolution at the University of Chicago. His concentration is speciation and ecological and evolutionary genetics, particularly as they involve Drosophila
His work is widely published, not only in scientific journals, but also in such mainstream venues as The New York Times, the Times Literary Supplement, and The New Republic. Coyne's peer-reviewed scientific publications include three papers in Nature and two in Science.
His research interests include population and evolutionary genetics, speciation, ecological and quantitative genetics, chromosome evolution, and sperm competition.
I really liked this book, and it truly is one of the great works of evolutionary biology to come out in the past decade. A wonderful, in-depth, and interesting summary of the field of speciation research. Coyne and Orr do show their biases (and the book does have a heavy Drosophila melanogaster focus), but that is actually quite refreshing, because they don't often obscure other points of view -- they take a very balanced approach in most chapters. It's a great read for scientists, but not recommended for the general reader, as it is still quite technical and dense.
