His Khan Academy profile says he lives in Oxford, United Kingdom.
Peter currently works as a freelance as a content creator for Khan Academy, making dynamic math exercises and science simulations. Before that Peter was a postdoc at the Marine Biological Association in Plymouth, researching calcium signaling in the flagella of green algae called Chlamydomonas reinhardtii. He did his Ph.D. research on the human parasite, Trypanosoma brucei, which causes sleeping sickness. He did at the University of Oxford, where he also did an undergraduate Masters degree in Biochemistry
Peter Collingridge has a degree in biochemistry and a Ph.D. in pathology from the University of Oxford. After graduating he researched cell signaling at a marine biology lab. There he taught himself coding so he could develop a bioinformatic algorithm for better aligning protein sequences and then simulate the 3D motion of a cell as it swam. It was at that time he also started volunteering at Khan Academy, answering students' questions and creating online programs to explain and explore concepts.
Now he works as a freelance programmer, spending most of his time as a content creator for Khan Academy. Most recently he built the interactive elements for a series of lessons explaining the mathematics behind Pixar's movies.
