Current Research Projects

• Rapid-scan radar analysis and applications: Assess the impact of various radar scan speedup methods on data quality and early tornado detection within a rapid-scan framework
• Bistatic/multistatic radar applications: Simulate scattering from a bistatic/multistatic weather radar system to assess polarimetric signatures and wind retrieval methods
• Radar simulations: Modifying a small-domain radar simulator (C-based) and a large-domain radar simulator (C/C++ and Matlab-based) to support various radar scan modes and interpolation schemes
• Data assimilation: Calculation of error estimates in various radar scan modes, to assess the impact of data quality on numerical weather prediction (NWP) model performance after data assimilation
• Field work and data collection: Work to collect supercell and tornado data using mobile radar platforms. Responsibilities include maintaining, running, and troubleshooting the radar, processing and cataloging the data, and using the data for further research
• Tornado dynamics: Studying a 60-90 second periodicity in tornado strength using datasets from multiple radar platforms
• Wind retrieval methods: Working on a potential improvement to the ground-based velocity track display (GBVTD) method using cost function minimization, and testing the results via a radar simulator
• Tornadogenesis failure: Currently advising an undergraduate student with a case study on strongly rotating supercells that did not produce a tornado
• Collaborations with non-ARRC researchers: Provided and/or collected data for collaborations with Dr. Roger Wakimoto, Dr. Wen-Chau Lee, Dr. Larry Frank, and Dr. Alan Shapiro

Previous Research Projects

• Tornado dynamics: Led a study on the features of the 16 May 2015 "Tipton, OK" tornado using data from the Atmospheric Imaging Radar (Publication Link) and assisted with a study of the 27 May 2015 "Canadian, TX" tornado (Publication Link)
• Radar applications and cold front structure: Analyzed the vertical structure of a cold front at high spatiotemporal resolution (Publication Link)
• Collaborations with non-ARRC researchers: Collaborated with Dr. Junichi Furumoto of Kyoto University (KU) by creating batch scripts for the KU supercomputer to process radar data and helping to develop plans for a real-time beamforming system for the Atmospheric Imaging Radar
