Throughout her years in clinical research, Cindy managed and oversaw numerous clinical trials, honing her project management skills. She is now excited to be applying her extensive project management skills to support the award-winning and innovative work of the Nucleus production team.
In her free time, Cindy enjoys reading, time with friends and family, including her two dogs, beach vacations, movies, music, and singing at the top of her lungs in her car even though she can’t carry a tune.

Mary Beth Clough
Senior Medical Editor
Born and raised in Cleveland, Ohio, Mary Beth has made Atlanta her home since 1992 – but sometimes, she misses the snow. Her love of art and science first led her to the Cleveland Institute of Art, where she earned a Bachelor of Fine Arts degree in Medical Illustration. Craving more knowledge, she moved on to get a Master of Science degree in Medical Illustration from the Medical College of Georgia.
She began her career at A.D.A.M., Inc., where she illustrated, animated, and wrote medical animation scripts for the world’s first dissectible human software. Visual storytelling experience and medical knowledge gained from that work led to an opportunity at Nucleus to focus solely on writing medical animation scripts. Since 2006, she has written or edited over 1,000 scripts for a variety of objectives and audiences. She derives great satisfaction from the “aha” moment when viewers finally understand something about science or their body after viewing a Nucleus animation.
When not staring at a computer, she works in her yard, watches classic sci-fi movies (“Alien” is a favorite), travels, reads, or spends time with family.

Damian Williamson
Senior Medical Illustrator, Maintenance Director

He quickly became an integral part of the MLA team, creating exhibits and animations, brainstorming on case strategies, and ensuring the walls in the office weren’t crumbling down.
You will have a hard time finding Damian sitting still when he isn’t behind the screen. The challenge of soaking in new knowledge and learning new skills pushes him. From painting, building furniture and houses, restoring cars, playing in bands, masonry, and welding to writing, there isn’t enough time in the day. Still, when those are done, it’s time for the gym, hiking, traveling, movies, repeat.
