Marcus Cappelli, AE 03, MS AE 04, PhD AE 07 - Chief Engineer, Black Hawk Modernization | Lockheed Martin

As the chief engineer responsible for modernizing the nation’s fleet of Black Hawk helicopters, Marcus Cappelli is well aware that he’s found his dream job. And, it’s not only the ultramodern upgrades like making the aircraft autonomous or equipping it with bigger engines to reach the peaks of Afghanistan for rescue missions that inspire him. (Although he and his team are making those upgrades, too.) Sometimes, the most meaningful changes are much simpler, he says. “The No. 1 request from our soldiers is for a simple battery charger under their seat, so they can stay in the field just a few hours longer,” he says. The result is a Black Hawk helicopter ready to fulfill any future mission. “Every day thousands of enlisted soldiers will get into my product and possibly have to do it putting their life on the line for my freedom. That is the very definition of committed, a commitment that we all need to match,” Marcus says.

Inspired by the universal language of music, he founded the YouTube channel Chord Savvy and has brought his Martin Backpacker travel guitar with him to more than 40 countries. “This guitar ran the songwriting clinic at First Step Academy in Jaipur, India, and played Imagine on a bus in Bulgaria to inspire people from 10 countries to ‘be as one,’” he says. “I am eternally grateful for the opportunity to share music globally and feel the hearts of people through it.” 

Christopher Hermann, BME 06, MS ME 11, PhD BioE 12

Christopher Hermann

Christopher Hermann, BME 06, MS ME 11, PhD BioE 12 - Founder & CEO | Clean Hands-Safe Hands

Christopher Hermann knows that engineers and healthcare providers don’t always speak the same language. The result can be a well-intentioned medical product that gets lost in translation and fails to deliver for the end-user. The first example that Christopher saw of this was as an undergrad at Tech. He was working closely with a surgeon to develop a new technique for a total knee replacement. “I remember the first time he performed the new procedure and quickly discovered the surgical implants that the engineers designed would not even fit in the incision,” he says. Christopher became a physician with an engineering background to help him provide solutions to bridge that disconnect. In 2008, he turned to healthcare-associated infections and learned that hand hygiene was a major contributor. He started and led a multi-intuitional research consortium (Georgia Tech is a member) that developed the core technology used in Clean Hands – Safe Hands. Using sensors in badges and on sanitizers and soap dispensers, the technology gathers data about handwashing and helps improve hand hygiene in healthcare facilities. Over 10 years, the research team has secured more than eight state and federal research grants totaling more than $3.2 million.

Ignacio Montoya

Ignacio Montoya, MBID 18 - Executive Director | HINRI Labs

Ignacio Montoya wants to find the cure for paralysis and get every person in a wheelchair walking again. And, he’s starting with himself. Seven years ago, Ingacio was in a car accident that caused a total spinal injury leaving him physically paralyzed. He woke up three months after the accident determined to walk again despite a bleak prognosis. But, Ingacio has beaten the odds before. At 6 years old, he escaped from Cuba with his family and nothing but the clothes on his back. He beat the odds again becoming a fighter pilot in the U.S. Air Force. And now, with a biomedical engineering degree from Tech, he’s leading HINRI Labs in the research of spinal cord injuries and testing, experimenting, and developing biomedical devices using his own body as a test subject. Ignacio recently became the first person to walk 650 miles in an exoskeleton-orthosis device suspended over a treadmill. He also recently drove the first-ever wheelchair adapted Ford Explorer with a one-handed double-piston joystick from Atlanta to L.A. Through his own body and indomitable determination, Ignacio is proving that recovery from a total spine injury is possible.

Emily Woods, ME 10

Emily Woods

Emily Woods, ME 10 - COO & Co-founder | Sanivation 

Emily Woods and her co-founder of Sanivation had a bold idea for global sanitation. “If we could treat feces more efficiently than traditional means—turn the treated waste into a product we could sell, we could make a profit from poop,” Emily says. She co-founded Sanivation to do just that. The social enterprise tackles the sanitation crisis in Kenya by partnering with municipalities to turn feces into a sustainable fuel. “We use our proprietary treatment technology to treat waste and transform it into an in-demand fuel,” Emily says. “Then, we sell the briquettes back on the market, creating a financially sustainable and replicable model for sanitation services.” The fuel also helps combat deforestation saving 88 trees per ton. “I would encourage GT students to think outside of the standard box of what people think success is,” she says.
