When she was five years old, Arlyne Simon decided she would be an inventor. She had never seen an inventor who looked like her, but was determined to pursue her dream regardless. Arlyne grew up to invent a blood test that can detect when cancer patients reject their bone marrow transplants, designed medical imaging equipment, and even taught Kenyan lab workers how to build supercomputers. Alongside her biomedical engineering career, Arlyne is a children’s book author. With her “Abby Invents” series, she is inspiring the next generation of engineers.
