Alejandro Palandjoglou. He just won the student division of Core 77 Design Award for Social Impact . His project, the Adaptair Pediatric Nasal Interface, which he developed along with a team of medical and business students, is a simple and affordable way to deliver effective respiratory treatment for children who suffer from life threatening illnesses. I'd say that's a social impact.
In addition to his outstanding problem solving skills, Ale is a gifted form-giver who has an undergraduate degree in ID and had his own furniture company back home in Argentina. His strong work ethic, hands on approach, sense of humor and good taste represent the best qualities of the Stanford Graduate Design Program.
Way to go, Ale. You're a star.
