Welcome to my home page!

I am a Research Scientist with the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) at the University of Oklahoma. I am also affiliated with the National Severe Storms Laboratory (NSSL).

My background is in Electrical Engineering, and I have over 10 years of experience in the field of weather radar signal processing. I am a member of the Doppler Radar and Remote Sensing Research group within the Radar Research and Development Division at NSSL where I work on:

leading the implementation of traditional and advanced signal processing techniques for the National Weather Radar Testbed (NWRT) Phased-Array Radar (PAR),
transferring these techniques to the operational network of weather surveillance Doppler radars (NEXRAD), and
developing new signal processing techniques for improved spectral moment and polarimetric variable estimation.

For more details about myself and the projects that I am currently working on, please take a look at my resume/CV and visit my research page.

What's new?

New algorithm to mitigate range and velocity ambiguities ready for operational implementation

In our 2009 annual report to the NWS Radar Operations Center, we document the staggered pulse-repetition-time (SPRT) algorithm that will become part of the NEXRAD network in the near future.

Keynote address at the International Radar Conference

I was invited to speak at the 2009 International Radar Conference in Bordeaux, France on Multifunction Phased Array Radar for weather and aircraft surveillance.

Adaptive scanning demonstrated on the NWRT Phased-Array Radar!

During the Spring of 2009, we successfully demonstrated the adaptive scanning capabilites of a phased-array radar.
