Associate Research Scientist, Atmospheric Science
⇒18 years experience working as a research and forecast meteorologist.
⇒ Worked on projects relating to: aviation icing forecasting, weather modification research and operations, wind turbine icing, energy weather product development, and aircraft cloud instrumentation.
⇒ Demonstrated expertise in supercooled cloud physics. Expert in identifying, analyzing, and differentiating clouds that contain supercooled liquid water, ice, and mixed phase.
⇒ Expert knowledge working with research aircraft data sets that include cloud particle and aerosol measurements.
⇒ Icing weather forecaster and data analyst for research aircraft.
⇒ Demonstrated expertise working with climate data sets.
⇒ Experience working with and verifying numerical weather data.
⇒ Expert analyst of most observational data types, radar and satellite imagery, as well as high-resolution numerical model output. Using these data I co-developed operational diagnostic and forecast cloud models that detect supercooled liquid water and tropical clouds containing high mass concentrations of small ice crystals. These systems passed peer review and meet the needs of the general aviation community. Examples include CIP and FIP, which are used as guidance at the Aviation Weather Center. http://www.aviationweather.gov/adds/icing/
⇒ Expert knowledge testing and verifying numerical model output.
⇒ Extensive experience working with large programs using software tools and programming languages such as; UNIX, Matlab, C++, FORTRAN, and shell scripting.
