I am a research scientist with the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) at the University of Oklahoma (OU), where I am affiliated with the National Severe Storms Laboratory (NSSL).
My background is in electrical engineering, and I have over 15 years of experience in the field of weather radar signal processing. I am the leader of the Advanced Radar Techniques (ART) group within the Radar Research and Development Division at NSSL where I work on:

In a 2008 survey about scanning strategy improvements for the WSR-88D conducted by the US National Weather Service (NWS), 62% of forecasters indicated the need for faster updates. High-temporal resolution data (~1 min) is expected to improve the understanding, detection, and warning of hazardous weather phenomena.
Faster data updates like those demonstrated with the

With faster updates as one of our major goals, significant hardware, software infrastructure, and signal processing upgrades continue to be accomplished to support the NWRT mission as a demonstrator system for the Multi-function Phased-Array Radar (MPAR) concept.
Two methods are currently exploited to reduce scan times without sacrificing data precision or spatial sampling: adaptive range oversampling and focused observations. The latter can be possible through a series of improvements to the radar's scan control functionality. These are summarized in our latest conference paper presented at the 2011 AMS Annual Meeting in Seattle, WA..
Through continuous engineering upgrades, we are able to demonstrate that PAR technology can be exploited to achieve performance levels that are unfeasible with current operational technology. Nonetheless, more research is needed to translate these improvements into concrete, measurable, and meaningful service improvements.
In our last annual report to the NWS Radar Operations Center, we document the CLEAN-AP filter, which will become part of the NEXRAD network in the near future.
The Spring 2012 software release on the NWRT PAR is now operational. This release includes improvements to the adaptive pedestal control algorithm, a surveillance mode to complement ADAPTS, and several improvements to our archiving and playback capabilities.
The Argentine government approved a plan to design, build, and install a national network of weather radars. On Nov. 2011, I was invited by INVAP S.E., the company in charge of this development, to provide consulting services and to teach a short course.
The second summit between Kyoto University and the University of Oklahoma took place at the National Weather Center on Sept. 14-16, 2011. I was the chairman of the local organizing committee, a role that was both exhausting and rewarding.
On May 18, I was interviewed by Rick Mitchell, chief meteorologist from Oklahoma City channel 5 (KOCO).
