Thomas C Grubb, Jr. is Professor Emeritus of Zoology at Ohio State University. He has had an interest in field biology since early childhood, when he was what he now calls a "log-turner," one who turns over logs out of curiosity about what might be underneath. He was astounded to discover that one could earn a living as a sophisticated "log-turner" and pursued a career as biologist. His research focuses on responses to forest fragmentation, avian hybridization, and foraging ecology.
