Mechanical and aerospace engineer Dr. Afsaneh Rabiei set out to create a material "as light as aluminum and as strong as stainless steel," and she has succeeded, in the form of composite metal foam. In this Science Nation video, she discusses its applications as a building material, a way to make car bumpers stronger, and a superior substitute to solid metal in knee and hip surgeries. A professor at North Carolina State University, Dr. Rabiei encourages her students to be "persistent and pioneering." In her spare time, one of her passions is introducing grade school children to the wonders of engineering.
