Elizabeth McDonald

Art Director

Born and raised in Alabama, Elizabeth decided to hop one state over to put down roots. She received a BFA in Scientific Illustration from the University of Georgia and a Master's of Science in Medical Illustration from Augusta University. Upon graduation, she dove into the world of 3D animation and never looked back. Elizabeth has been with Nucleus for almost 10 years. She enjoys collaborating directly with clients, new and old, to bring their story to life in new and interesting ways. Her favorite part of working at Nucleus is being able to animate a wide variety of subject matter. There is never a dull day. She draws inspiration for each project from current trends in animation and the talented team of animators who work alongside her. Outside of the office, Elizabeth can be found experimenting in the kitchen, running or hiking, painting pet portraits, visiting a local brewery, or chasing her cats around the house.

Nobles Green

Senior Medical Animator

Fascinated with visualizing anatomical and cellular science, Nobles left his hometown of Memphis, TN to move to Georgia, where he pursued his Bachelor of Arts in Oglethorpe University and a Master of Science in Medical Illustration at Medical College of Georgia. Being one of the first 3d animators in Nucleus has helped Nobles benefit from over a decade of experience in creating award winning medical animations and he enjoys the variety of subject matter and creative opportunities that each project brings. Dedicated to this unique industry, he has served on the Board of Governors of the Association of Medical Illustrators (AMI) and helped establish and lead its Diversity Committee, which strives to increase diverse and inclusive representation within AMI's membership and leadership. His active participation in the AMI has encouraged him to remain cognizant of new perspectives, technologies, and skills. He also enjoys spending time with his wife and kids, especially during their family game nights, which typically involves pizza and multi-player Nintendo games. It is serious business in the Green household!

What he finds most engaging about the profession is witnessing the advancement of medical innovation and using the ever-changing trend and technology in visual storytelling to share it with the world. He is currently serving on the Board of Governors for the Association of Medical Illustrators. When he is not in front of his computer, Hoc enjoys working out, running, hiking, and playing basketball and tennis. He also occasionally juggles and rides his unicycles.
