M.S. Meteorology, University of Oklahoma
B.S. Physics (Honors Option), cum laude, University of Texas at Austin

Current Research Projects as of February 2020

  • 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
  • Radar simulations: Modifying a small-domain radar simulator (C-based) and a large-domain radar simulator (Matlab and C-based) to support various radar scan modes and time 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 previous data and/or collected new data for collaborations with Dr. Roger Wakimoto, Dr. Wen-Chau Lee, Dr. Larry Frank, and Dr. Alan Shapiro

Recent Research Projects

  • Bistatic/multistatic radar applications: Simulate scattering from a bistatic/multistatic weather radar system to assess polarimetric signatures and wind retrieval methods
  • Tornado dynamics: Led a study on the features of 16 May 2015 "Tipton, OK" tornado using data from the Atmospheric Imaging Radar (Publication Link), and assisted on a study of the 27 May 2015 "Canadian, TX" tornado (Publication Link)
  • Radar applications & cold front structure: Analyzed a passing cold front at high spatiotemporal resolution (M.S. Thesis Link; 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, reformatted data for a tornadic analysis case study, and helped develop plans for a real-time beamforming system for the Atmospheric Imaging Radar (AIR)
