John was born and grew up in Kitchener-Waterloo, Ontario, which instilled in him a deep love for good maple syrup and summer sausage, among other things.

John's research interests are in developmental biology and cell biology. He is particularly curious about the development of germ cells—the lineage of cells that divide and mature to become eggs and sperm. Due to their capacity to generate a new individual via fertilization, germ cells are in a sense the ultimate stem cells in sexually reproducing organisms. In most animals, these special cells arise as a distinct lineage very early in embryonic development, and remain distinct from the rest of the body's "somatic" cells. In a group of flatworms known as planarians, however, germ cells can develop "de novo" in adults, from a remarkable set of somatic stem cells known as neoblasts. Thus, planarian worms are an intriguing and readily accessible model system in which to study germ cell origins and development, which John is beginning to explore with the help of some wonderful colleagues at the Morgridge Institute for Research in Madison Wisconsin.

Among John's other academic interests are the interaction between the natural sciences, philosophy and theology, which makes CMU an exciting place for him to be.

When he has time on his hands, John enjoys cycling, canoeing, volleyball, curling, singing, and being entertained by his Senegal parrot.
