Terri Po grew up in Hong Kong and studied illustration at the University of Edinburgh, and now lives and works from a wooden cabin in the countryside. She likes drawing anything blobby, including but not limited to: brains, intestines and liverworts.

"A tiny, powerful investigative team of body cells uncover the mystery of a young girl's gastrointestinal illness in Tummy Trouble, the first title in Ben Elcomb and Terri Po's delightfully engrossing nonfiction picture book series Diagnosis Detectives. [...] The book's winning treatment of clear, accurate data and a lighthearted whodunit plot provide plenty of opportunity for discovery and DIY activities offer a fun way to engage with the material, like using glitter to model the transference of food particles."

"Invaders and protectors face off in the human digestive system. Po's artwork combines imagination with accuracy; the central players are portrayed both as they appear under a microscope and in their blobby, cartoonish forms. [...] A STEAM winner, sure to inspire future physicians--and reassure young hypochondriacs."
