Congratulations to Lydia Gregg, MA, CMI, FAMI, on her receipt of a 2018 Catalyst Award, an intramural $75,000 grant!

Lydia is an Associate Professor with a joint appointment in the Departments of Radiology and Art as Applied to Medicine. Her funded project entitled, Communicating Comparative Embryonic Arterial Development: An Interactive 3D Educational Tool Depicting Zebrafish and Human Ocular Arteries, seeks to visualize the development of major intracranial and ocular arteries by creating a comparative 3D educational tool that integrates human serial section data and zebrafish confocal microscopy data (Fig. 1). Developing this dynamic visualization will build on Lydia’s prior neurovascular embryology work (Fig. 2) 1-4 and experience illustrating, animating, and researching neurovascular anatomy 5-8.
