Ronald Mathias talks to us about his field of medical illustration: the art of taking complex medical procedures, descriptions, or concepts and turning them into something visual for ease of understanding. He spends most of his time translating traumatic injuries and building empathy for the pain someone has suffered into a visual medium for litigation. He is also tasked with the extremely difficult job of taking the unseen symptoms and turning them into visual representations. 

For the cover of the book Superhero Grief, Ron designed the cover to help the reader understand the transformation that even Superheroes go through. Every person, superhero or not, goes through grief at some point in their lives. Each person has to leave something behind to transform into the new person that they have become. Superheroes are imperfect like us and can have trouble moving on from the trauma they have endured.
