Kristina M. Johnson. Kristina M. Johnson (born May 7, 1957) is an American professorial electrical engineer, business executive and academic administrator.  She is an elected member of the National Academy of Engineering.

She previously served as the 13th chancellor of the State University of New York from 2017 to 2020 and the 16th president of Ohio State University from 2020 to 2023. She has knowledge in the development of optoelectronic processing systems, 3-D imaging, and color-management systems.

Early life and education
Johnson was born in St. Louis, Missouri, and grew up in Denver, Colorado. As a senior at Thomas Jefferson High School, she won the Denver City and Colorado State science fair competition, and placed second in the Physics division and a first place award from the Air Force at the International Science Fair for her project entitled, "Holographic Study of the Sporangiophore Phycomyces". Johnson grew up in a large, athletic family. She competed in Tae Kwon Do and learned to play lacrosse on the boys' lacrosse team. Her paternal grandfather, Charles W. Johnson, attended the Ohio State University and played football for the Buckeyes in 1896; Johnson would eventually become president there.

As an undergraduate at Stanford University, Johnson founded the women's club lacrosse team (now varsity) and played on the field hockey team, trying out for the U.S. Team in 1978. In 1979, Johnson was diagnosed with Hodgkin's disease and turned her focus to an academic career. Johnson received her B.S., M.S., and Ph.D. degrees in electrical engineering from Stanford, and was a postdoctoral fellow at Trinity College Dublin.

Career
After the postdoctoral fellowship, Johnson was appointed assistant professor of electrical and computer engineering at the University of Colorado Boulder in 1985, where she co-founded the National Science Foundation (NSF) Engineering Research Center (ERC) for Optoelectronic Computing Systems and spun off several companies from her research laboratory including ColorLink, Inc which was later sold to RealD, responsible for the technology that helped re-launch the 3D movie industry. Additionally, she co-founded the Colorado Advanced Technology Institute Center of Excellence in Optoelectronics. In 1999, Johnson was appointed Dean of the School of Engineering at Duke University, which would be later named for distinguished alumnus, Edmund T. Pratt Jr., CEO emeritus of Pfizer Corporation.

In 2007, Johnson became the Senior Vice-President and Provost of Johns Hopkins University. In 2009, Johnson was appointed by President Obama as the Under Secretary of Energy for Energy and Environment at the United States Department of Energy with the unanimous consent of the United States Senate.

She is the founder of Enduring Hydro, a hydropower-focused energy firm. The firm has a joint venture with the New York City-based private equity firm I Squared Capital (called Cube Hydro Partners), that owns and operates 19 hydropower plants in the Eastern United States.

Johnson was elected a member of the National Academy of Engineering in 2016 for the development and deployment of liquid crystal on silicon display technologies, the basis for high-speed optoelectronic 3D imaging.

Johnson has been a director of Minerals Technologies Inc., Nortel, Guidant Corporation, AES Corporation, and Boston Scientific. She is currently a member of the Board of Directors of Cisco Systems. In 2019, she resigned from the board of AES Corporation amid criticism of the company's pollution in Puerto Rico.

In April 2017, Johnson was appointed chancellor of the 64-school State University of New York, assuming the role in September.

On June 3, 2020, it was announced that Johnson would resign from her position at the State University of New York to become the next President of Ohio State University. Under her presidency at Ohio State, research spending increased by 42%, and faculty attrition was reversed. In addition, significant funds were raised for the university and scholarships increased.

Ohio State University resignation controversy 
In 2011, billionaire businessman and former Ohio State Board of Trustees member Les Wexner, who had close ties to convicted child sex trafficker Jeffrey Epstein, pledged a $100 million donation to Ohio State. In 2012, then-president E. Gordon Gee commemorated Wexner's "lifelong legacy of leadership at the Ohio State", renaming the Ohio State University Medical Center to the Wexner Medical Center.

In 2023, Johnson "shocked the Ohio State University community" when she resigned from her position as president "just halfway through her contract". According to The Columbus Dispatch, this was due to Johnson deciding "she could no longer work with Les Wexner and certain trustees who are loyal to him and who push for his interests". Sources told The Columbus Dispatch that "Johnson and university leaders agreed not to speak publicly about the details surrounding her resignation", and she was replaced by Walter E. Carter Jr. the following school year.

Personal life 
Johnson is married to Veronica Meinhard, Founder and President of Juniper Philanthropy Partners.
