  •  Dr. Nat's TEDx talk: "How engineers can help doctors save lives"

    In "How engineers can help doctors save lives", Dr. Nataraj describes the human body as a complex dynamic system that cannot be fully understood by conventional medical diagnostics. Given the diversity of the human race, it is difficult to define "normal" and as a result, millions of patients are incorrectly diagnosed each year, leading to unnecessary treatments and death.

    Dr. Nataraj believes engineers can offer a solution: "physics, mathematics and computer algorithms can be used effectively and intelligently to make this situation a whole lot better," he says.

    During his talk, Dr. Nataraj discussed these ideas and shared results from research he is conducting with the Children's Hospital of Philadelphia (CHOP).

    In collaboration with CHOP doctors, he is applying a machinery diagnostic approach to studying data on periventricular leukomalacia, a mysterious neurological damage that occurs in neonates.
