Tim received his PhD from the City University of New York, where he studied the signaling mechanisms that underlie the promotion of axonal growth and regeneration following injury in the laboratory of Marie Filbin. He then moved to the laboratory of Chris Henderson at Columbia University, where he examined molecular markers of postnatal motor neuron maturation and elements of motor-specific disease. Tim served as a Senior Scientific Editor at Nature Neuroscience since 2011 before moving to RUP to become the Deputy Editor of the Journal of Cell Biology in 2016. He became Executive Editor in 2019.
