CV

Bio: Dr. Ruppert is an Assistant Professor in OU’s School of Meteorology. He joined the School in 2021. He received his B.S. in 2009 from the University at Albany and his M.S. (2012) and Ph.D. (2015) degrees from Colorado State University. He then conducted his postdoctoral studies at the Max Planck Institute for Meteorology in Hamburg, Germany, supported by fellowships from the US National Science Foundation and German Alexander von Humboldt Foundation. Following his postdoc he held a position as Assistant Research Professor in Penn State’s ADAPT Center (Advanced Data Assimilation and Predictability Techniques).

Dr. Ruppert has always been fascinated by the links between large-scale circulation, convection, and climate, and the ways to understand these links through a range of lenses—from applied to theoretical, from case study to idealized numerical experiment. His research often focuses on the dynamics of moist convection, tropical cyclones (hurricanes), monsoons, the Madden–Julian Oscillation, gravity waves, and the diurnal cycle.
