Dave joined the University of Iowa in 2015 as a Postdoctoral Research Scholar working on the NASA Van Allen Probes mission, moving from Lancaster University in the UK.  In 2018, Dave became an Assistant Research Scientist, using in-situ spacecraft observations to study the dynamics of the Earth’s magnetosphere.  He uses plasma wave observations from the EMFISIS instrument on NASA’s Van Allen Probes satellite mission, as well as MMS measurements, to study very low frequency (VLF) waves which play a critical role in driving variations in the different particle populations contained within the inner magnetosphere.  Dave is currently Principal Investigator of two NASA grants, and Co-Investigator on an NSF-GEM grant, as well as Early Career Representative for Commission H (Waves in Plasmas) of the International Union of Radio Science (URSI).  Outside of work, Dave loves to explore new places, travel, and play football (soccer).
