The new Miss USA beauty queen is a emergency specialist with the US nuclear regulator.
Kara McCullogh, a 25-year-old from the District of Columbia, originally started in the Nuclear Regulatory Commission’s young talent programme.
She now works in the Office of Nuclear Security and Incident Response as an emergency preparedness specialist.
She regularly reviews emergency plans for both new and operating nuclear facilities, including power plants.
But on Sunday night the Naples born 5ft 10inch model managed to beat the competition to be crowned Miss USA in the annual pageant.
According to the Miss USA website, McCullough has a penchant for cooking specialty Italian and soul food cuisines.
She earned her Bachelor of Science degree in Chemistry with a concentration in Radiochemistry from South Carolina State University.
Her major provided her the opportunity to intern at many universities, which paved the way to her current career at the United States Nuclear Regulatory Commission.
McCullough also has a personal community outreach program entitled, Science Exploration for Kids (SE4K).
SE4K features interactive science activities, and math and science tutoring for children scholars grades 6-11.
