It’s not often that you find an athlete, engineer, musician, and a former Miss America all in one. Grace Stanke breaks misconceptions surrounding nuclear energy through social media, public engagements, and educational workshops. During her year as Miss America 2023, Grace was named the “New Face of Nuclear Energy” by the Wall Street Journal and was on the Forbes 30 under 30 list for Energy. While completing approximately 270,000 miles of travel, she finished her undergraduate degree in Nuclear Engineering from the University of Wisconsin-Madison. Since passing on the title of Miss America, Grace continues to advocate for peaceful purposes of the science of the atom. She was recognized by CNET as part of the four women powering America’s Clean Energy Transition. By encouraging worldwide change for clean, zero-carbon emission energy sources, Stanke emphasizes the benefits of nuclear power and seeks to dispel the myths around nuclear energy while inspiring the next generation of scientists, engineers, and mathematicians.
