As a teen, D. K. Yamashiro survived falling four hundred feet from a ridge in Hawaii, suffering severe brain injuries. Years of recovery involved a camel ride at the Pyramids of Giza, swimming in the Mediterranean Sea, hiking up Masada, sledding down the Great Wall of China, exploring underground caves in the Black Hills, and speaking to crowds in East Africa and Brazilian favelas. A master’s at Harvard and summer studies at Oxford preceded a PhD with research on childhood traumas of American presidents. Yamashiro is an affiliate at MIT.
