Roddy received his B.S. in geology at the Midwestern State University, before starting his graduate program at Texas A&M University, focusing on hydrogeology. Roddy transferred to the department of Earth and Atmospheric Sciences at University of Nebraska-Lincoln, where he continued to studied hydrogeology and graduated with his M.S. in August, 2018.
While attending Texas A&M, Roddy worked in a commercial soils laboratory, where they prepared soil samples for the various analytical tests. He began working at the Water Sciences Laboratory during his graduate studies, and transitioned to a new position after graduation. During his time at the Water Sciences Lab, Roddy help construct the Helix SFT noble gas mass spectrometer and extraction system and conducted much of the method development for analyzing samples for dating young groundwater using the tritium/helium-3 method. In addition, he is also trained to analyze samples on other instruments including the Atomic Absorption spectrometer, the Seal AQ2 auto analyzer, and Ion Chromatograph.
