Bio
Dr. Greenquist earned his BS in Chemical Engineering from Brigham Young University in 2015. He earned his PhD in Nuclear Engineering from Penn State University in 2019. His graduate research was to develop a first-of-kind mesoscale mechanistic model of sintering and irradiation-enhanced densification in UO2 fuel.
He joined Oak Ridge in 2019 as a Postdoctoral Research Associate to perform BISON simulations of metallic fuels to support the Versatile Test Reactor Project. In his current role he performs fuel performance and multiphysics simulations of a wide array of nuclear fuel and reactor concepts such as high burnup fuels, microreactors, and advanced fuel concepts. He also performs code coupling, development, and validation of next-generation nuclear physics codes. In his spare time Ian hikes, whittles, and spends time with his wife and three daughters.
