Before joining Ramboll, Dr. Lemmon served from 2022 to 2024 as a climate technology portfolio analysis adviser at the Office of Clean Energy Demonstrations within the U.S. Department of Energy. As one of the first 100 employees in this newly established office, she played a pivotal role in shaping its direction under the Bipartisan Infrastructure Law’s $27 billion mandate. Dr. Lemmon’s most significant achievement during this period was the development of portfolio tools for long-duration energy storage decisions, a critical advancement for grid-scale renewable energy integration. Her evidence-based analysis integrated data from national laboratories and demographic research to identify communities vulnerable to frequent power outages, ultimately enhancing resilience for homes, hospitals and defense facilities. Dr. Lemmon also contributed to major initiatives, such as the $8 billion hydrogen hubs program, and received recognition from Secretary Jennifer Granholm for her impact on clean energy policy.
From 2020 to 2022, Dr. Lemmon was a postdoctoral research fellow in climate and human evolution at the IBS Center for Climate Physics in South Korea. There, she investigated how long-term climate shifts over the past two million years influenced human evolution and migration patterns out of Africa. Dr. Lemmon’s collaborative research resulted in co-authored publications in leading journals, including Nature and Science, working alongside mentors regarded as potential Nobel Prize candidates.
Dr. Lemmon’s academic journey began at the University of Washington, where she earned a Bachelor of Science in physics with a minor in atmospheric sciences in 2014. During her undergraduate years, she contributed as a glacial geology research assistant from 2011 to 2015 and served as a physics recitation instructor from 2012 to 2014. She then worked as a nuclear fusion research assistant at Woodruff Scientific from 2014 to 2015 before pursuing graduate studies.
At the University of Colorado Boulder, Dr. Lemmon completed a Doctor of Philosophy in atmospheric and oceanic sciences in 2020, a program renowned for its leadership in climate science. Her doctoral research focused on the El Niño Southern Oscillation, examining its potential changes under global warming and implications for food and water security. Dr. Lemmon also held roles as an atmospheric and oceanic sciences laboratory instructor from 2015 to 2018, graduate teacher program lead between 2018 and 2020 and National Science Foundation graduate research fellow from 2016 to 2020. She further enhanced her expertise by earning a graduate certificate in college teaching and a graduate certificate in science and technology policy from the University of Colorado Boulder in 2020.
Dr. Lemmon’s professional affiliations include membership with science and technology policy fellowships through the American Association for the Advancement of Science and recognition as a clean energy fellow by the Clean Energy Leadership Institute. Beyond her professional pursuits, she has demonstrated civic engagement as a lead of the American Society of Physics Students at the University of Washington and as a mentor for the SMART Program at the University of Colorado Boulder.
A dynamic media personality, Dr. Lemmon has appeared on the radio approximately a dozen times, including regular guest spots on Utah Public Radio’s “Undisciplined,” and has been featured on podcasts discussing topics such as changes under incoming presidential administrations.
