Alejandro De Los Angeles is a visiting researcher at Yale University. He has done research at several leading institutions, including Stanford, Yale, Columbia, and the Genome Institute of Singapore. A Connecticut native, he has published over 25 papers on stem cells and human-animal interspecies chimeras. Alejandro’s research has focused on identifying stem cells capable of forming interspecies chimeras. Recently, Alejandro discovered a new type of monkey pluripotent stem cell that might possess the capability of forming interspecies chimeras. He also showed that the same method works in human stem cells. De Los Angeles’s work has appeared in major scientific journals, including the top journal Nature. In addition to his scientific work in the laboratory, he also collaborates with bioethicists and recently co-edited a book on chimera research and ethics titled, “Chimera Research,” published by Springer Nature.
