Professor Roger Jacobs is Canadian Scientist and Professor in developmental genetics for 33 years and has published over 60 papers. His major contributions have employed the Drosophila genetic model to reveal mechanisms of cell fate determination, patterning, and axon guidance in the developing nervous system. He also studies heart development and growth in Drosophila. He is also Innovative Educator, having obtained competitive funding to develop and implement novel active learning curricula in five new courses on the scientific method, introductory molecular biology, science communication, and the course upon which this book is based—pedagogical use of case studies of how science speaks to power.
