It could appear that engineering is in Ritu Raman’s blood. Her mom is a chemical engineer, her father is a mechanical engineer, and her grandfather is a civil engineer. A standard thread amongst her childhood experiences was witnessing firsthand the helpful affect that engineering careers might have on communities. Considered one of her earliest recollections is watching her mother and father construct communication towers to attach the agricultural villages of Kenya to the worldwide infrastructure. She remembers the joy she felt watching the emergence of a bodily manifestation of innovation that might have a long-lasting optimistic affect on the neighborhood.
Raman is, as she places it, “a mechanical engineer by and thru.” She earned her BS, MS, and PhD in mechanical engineering. Her postdoc at MIT was funded by a L’Oréal USA for Girls in Science Fellowship and a Ford Basis Fellowship from the Nationwide Academies of Sciences Engineering and Drugs.
Right this moment, Ritu Raman leads the Raman Lab and is an assistant professor within the Division of Mechanical Engineering. However Raman shouldn’t be tied to conventional notions of what mechanical engineers must be constructing or the supplies usually related to the sphere. “As a mechanical engineer, I’ve pushed again towards the concept that individuals in my discipline solely construct vehicles and rockets from metals, polymers, and ceramics. I’m concerned with constructing with biology, with residing cells,” she says.
Our machines, from our telephones to our vehicles, are designed with very particular functions. And so they aren’t low cost. However a dropped cellphone or a crashed automotive might imply the tip of it, or on the very least an costly restore invoice. For essentially the most half, that isn’t the case with our our bodies. Organic supplies have an unparalleled means to sense, course of, and reply to their setting in real-time. “As people, if we reduce our pores and skin or if we fall, we’re in a position to heal,” says Raman. “So, I began questioning, ‘Why aren’t engineers constructing with the supplies which have these dynamically responsive capabilities?’”
Lately, Raman is targeted on constructing actuators (units that present motion) powered by neurons and skeletal muscle that may train us extra about how we transfer and the way we navigate the world. Particularly, she’s creating millimeter-scale fashions of skeletal muscle managed by the motor neurons that assist us plan and execute motion in addition to the sensory neurons that inform us how to answer dynamic adjustments in our surroundings.
Ultimately, her actuators might information the way in which to constructing higher robots. Right this moment, even our most superior robots are a far cry from with the ability to reproduce human movement — our means to run, leap, pivot on a dime, and alter course. However bioengineered muscle made in Raman’s lab has the potential to create robots which are extra dynamically conscious of their environments.
