Madison Li

Doctor  is a scientist working on food conditioning experiments in Rivet City, together with Janice Kaplinski and Anna Holt. She used to be part of the group of scientists that worked with James on Project Purity before the birth of the Lone Wanderer. Despite James' renewed efforts she remains skeptical of the project. Dr. Li is the first distinct face that the Player sees during the player character's birth scene.

The player is sent to Dr. Li by Three Dog after completing Galaxy News Radio (quest) (or talking his way out of it), beginning Scientific Pursuits. Li will send the player to Vault 112 based on a holotape James left behind.

After completing Scientific Pursuits, Dr. Li and James will begin working on Project Purity (The Waters of Life). She survives when Enclave forces invade towards the end of that quest, escaping into Taft Tunnel with the player and a few members of her research team.

Dr. Li chooses to stay at Citadel at the end of The Waters of Life, continuing her research in the safety found there. After the end of Project Purity Dr. Li has left for the Commonwealth to join the scientists, emotionally distraught over losses and struggles in the Capital Wasteland
