Larry has been the Radar Research and Development Division Chief at NSSL since September 2021 after serving as a National Weather Service (NWS) meteorologist for over seven years. Larry is leveraging his prior experience at NWS Austin-San Antonio and Phoenix working with meteorologists, emergency managers, private and public partners, and academia to help transition NSSL’s cooperative research to operations to improve the existing NEXRAD network while also developing phased array radar options for the next generation. Prior to his NWS career, Larry taught at the University of Louisiana at Monroe from 2011-14 and ran an NSF-sponsored undergraduate research and education program at Texas A&M University from 2005-10. In his spare time, Larry enjoys spending time with family and friends and playing and watching sports, especially his Sooners play basketball as an alumnus (student manager) of OU’s 2001-02 NCAA Men’s Final Four Basketball Team.
