Stephanie "Annie" Melchor got her PhD from the University of Virginia in 2020, studying how the immune response to the parasite Toxoplasma gondii leads to muscle wasting and tissue scarring in mice. While she is still an ardent immunology fangirl, she left the bench to become a science writer and received her master’s degree in science communication from the University of California, Santa Cruz, in 2021. You can check out more of her work here.
