As a child tinkering with household appliances in Michigan, Karlin Bark imagined a career in the automotive industry. But a class in haptics—the science of touch—took her in a new direction, eventually resulting in her efforts as a doctoral candidate to improve prosthetic limb fittings.

She is one of five female postdocs to receive the 2011 L’Oréal USA Fellowships for Women in Science.
