THE INSTITUTE Kristina M. Johnson has broken through barriers during her career. She became the first female dean of Duke University’s engineering school, the first female provost at Johns Hopkins University, and the first woman to receive the John Fritz Medal—in 2008—from the American Association of Engineering Societies.

This year the IEEE Fellow added another distinction: first recipient of the IEEE Mildred Dresselhaus Medal. Johnson received the recognition “for leadership and technical contributions spanning academia, government, and business.” The Dresselhaus Medal, introduced last year, recognizes outstanding technical contributions in science and engineering of great impact to IEEE fields of interest. It is sponsored by Google.

Dresselhaus, like Johnson, had a few firsts in her career. The life Fellow, who was a pioneer of the electronic properties of materials, in 2015 became the first woman to receive the IEEE Medal of Honor.

Johnson is an expert in photonics, specializing in optoelectronic processing systems. She holds more than 100 U.S. and international patents in the field.

She also founded several companies, but Johnson, who is president of the Ohio State University, in Columbus, says her true passion is academia.

“I just love teaching,” she says. “Seeing the light bulb go off in students’ heads is super exciting.”

She is an advocate for having a diverse faculty and student body, erasing student debt, and increasing interdisciplinary research.

MAKING HER MARK

Johnson grew up in Denver in a family of seven. When her older siblings were doing algebra homework, they would teach her how to do the math, Johnson says: “It was really fun to learn [algebra] when I was a preschooler. I loved it.”

Johnson went on to earn bachelor’s, master’s, and doctoral degrees—all in electrical engineering—at Stanford.

She began her academic career in 1985 at the University of Colorado at Boulder as an assistant professor of electrical and computer engineering. She was the university’s first female tenure-track faculty member.

While there she made sure to make her mark. In 1987 she and engineering professor W. Thomas Cathey, who died in 2016, received a U.S. National Science Foundation grant to establish the Engineering Research Center for optoelectronic computing systems at the University of Colorado and Colorado State University, in Fort Collins. The center focuses on creating optoelectronic devices and systems for computing signal processing and artificial intelligence. In its cross-disciplinary environment, students and professors collaborate with faculty from chemistry, mathematics, physics, and other fields.

It was at the engineering center that she and a team of researchers and graduate students developed the technology behind the RealD 3D projection system, which has been used in more than 300 movies including Avatar. RealD uses stereoscopic projection technology and polarization optics to create three-dimensional images.

Her work at the engineering center reinforced her commitment to increasing cross-disciplinary research in academia. It was a point of focus when in 1999 she became dean of the Pratt School of Engineering at Duke, in Durham, N.C.

While at Duke, Johnson tripled research funding and increased the university’s endowment tenfold. Some of the money was used to establish the Fitzpatrick Center for Interdisciplinary Engineering, Medicine, and Applied Sciences. The center supports cross-disciplinary research in bioengineering, communications, materials science, materials engineering, and photonics.

“When you take on really big problems that are important to society, they’re going to require understanding from multiple disciplines,” she says.

During her time at Duke, she increased the percentage of women faculty from 6 percent to 19 percent, according to her Ohio State biography.

“I love engineering, and I want everybody to be an engineer,” Johnson says. “We should be welcoming to anyone and everyone and ensure that anybody can maximize their inherent talent.”

She took her desire to advance cross-disciplinary research and diversity with her when she moved to Baltimore in 2007 to become provost and senior vice president at Johns Hopkins, and to the State University of New York, where she became chancellor in 2017.

Johnson launched Promoting Recruiting Opportunity, Diversity, Inclusion, and Growth, a SUNY program that aims to increase the number of faculty members from underrepresented groups and female teachers in STEM fields at the university’s 64 campuses.

Another initiative, SUNY Achieve, increased the graduation rate at the system’s two-year community colleges by 22 percent, according to Johnson’s biography.

Johnson was appointed president of Ohio State in June. While aiming to increase diversity and cross-disciplinary research at the university, she hopes to improve academic performance and reduce student debt.

“Dr. Johnson is committed to increasing the diversity on campus—not just racially but schools of thought,” Janice M. Bonsu, a fourth-year medical student at Ohio State told the university’s newspaper, The Lantern, in June.

SAVING THE ENVIRONMENT

Johnson took a break from academia in 2009, when she was appointed undersecretary in the U.S. Department of Energy by President Barack Obama.

“It was challenging,” she says of the position. “But it was great to be able to fund important clean-energy research, and support technology for the secretary [Steven Chu], the president, and the people.”

In April 2010, Johnson dealt with one of the largest environmental disasters in U.S. history: the Deepwater Horizon oil spill in the Gulf of Mexico. The government struggled to determine how much oil was being discharged into the ocean.

Johnson came up with the idea to use particle image velocimetry, a laser optical measurement technique, to estimate at what rate the oil was spilling into the sea.

“PIV allows you to measure fluid velocity using particles in the [water] flow, using a double-exposure hologram,” she says. “Once you determine the velocity, then you know how much oil is coming out.”

She quickly emailed Marcia McNutt, then head of the U.S. Geological Survey, who told Johnson that the USGS had the world’s best PIV system. It was deployed that week.

“That was one of the most exciting—maybe a little too exciting, but fun—things to do: be able to draw on my background and come up with a solution for at least part of the problem,” Johnson says.

After her term ended in 2010, Johnson tried her hand at being an entrepreneur. In 2011 she founded Enduring Hydro, which worked to build and support the hydropower industry. In 2014 the startup partnered with I Squared Capital—an investment firm that specializes in energy—to build, buy, and operate hydroelectric power plants in North America with the goal of producing enough clean energy to fully power 150,000 homes. She served as CEO of the joint venture—Cube Hydro Partners—until 2017, when she joined SUNY.

CONNECTING THROUGH IEEE

Johnson’s father and grandfather were IEEE members. She joined the organization while she was an undergraduate at Stanford.

“We used to have IEEE social hours once a week,” she recalls. “That was great because you could meet other students, and if you were having trouble in a class, you could find somebody that could help you.”

Johnson says IEEE is a great way “to bring people together around common interests and common goals,” and she values “being part of the largest professional society in the world.”

IEEE membership offers a wide range of benefits and opportunities for those who share a common interest in technology. If you are not already a member, consider joining IEEE and becoming part of a worldwide network of more than 400,000 students and professionals.

It was one of the prettiest sights I have ever seen: our homemade rocket floating down from the sky, slowed by a white-and-orange parachute that I had worked on during many nights at the dining room table. The 6.7-meter-tall Nexø II rocket was powered by a bipropellant engine designed and constructed by the Copenhagen Suborbitals team. The engine mixed ethanol and liquid oxygen together to produce a thrust of 5 kilonewtons, and the rocket soared to a height of 6,500 meters. Even more important, it came back down in one piece.

That successful mission in August 2018 was a huge step toward our goal of sending an amateur astronaut to the edge of space aboard one of our DIY rockets. We're now building the Spica rocket to fulfill that mission, and we hope to launch a crewed rocket about 10 years from now.

Copenhagen Suborbitals is the world's only crowdsourced crewed spaceflight program, funded to the tune of almost US $100,000 per year by hundreds of generous donors around the world. Our project is staffed by a motley crew of volunteers who have a wide variety of day jobs. We have plenty of engineers, as well as people like me, a pricing manager with a skydiving hobby. I'm also one of three candidates for the astronaut position.
