Holly A. Sullivan




Being able to incorporate animals into a career filled with art and learning are my main goals in life. As a science illustrator, I aim to educate as well as invoke interest and appreciation for science and the natural world through my artwork. I specialize in projects pertaining to zoology, evolutionary biology, natural science, veterinary medicine, and animal science.


When not working, I can be found wherever animals are. Whether it be out hiking and hoping to catch a glimpse of the elusive local wildlife, wrangling livestock, or spending time with my studio sidekick, Walden the dog.

I work full-time as a Graphic Artist and Scientific Illustrator at MIT Lincoln Laboratory. Outside of this position, I work part-time with Dr. Michael Lipnick at the University of California San Francisco Medical School/Open Critical Care as a contract Scientific Illustrator and Graphic Designer. 

When I have the time, I'm happy to take on freelance scientific illustration projects!
