Curriculum Vitae
Brief Bio
I grew up in Charm City - Baltimore, Maryland. I received a Bachelor's Degree in Meteorology from Penn State in 1990, then a Master's Degree in Atmospheric Science from Colorado State Univ in 1993, and a Ph.D. degree in Atmospheric and Oceanic Sciences from Univ of Colorado in 2016. It is fair to say that I am a weather geek.

Primary Research

   The primary focus of my research has been numerical weather modeling, particularly the parameterization of cloud physics and precipitation processes. In collaborations over the last few years, I developed a bulk microphysical parameterization for use in WRF, COAMPS, NEMS, and other mesoscale models consisting of a two-moment representation of cloud water, rain, and cloud ice plus one-moment prediction of snow and graupel. A version of this scheme is used in routine operations in the National Center for Environmental Prediction Rapid Refresh (RAP) model. The latest version of the scheme includes explicit treatment of aerosols as cloud condensation and ice nuclei. The scheme is extensively tested using numerous case studies from various field experiments and frequently compared to microphysical observations from research field projects. Besides observations, the scheme is also compared to various other two-moment bulk schemes (e.g. Morrison, Seifert, Milbrandt) and against results from more sophisticated explicit/bin/spectral schemes (e.g. Geresdi, Khain and Lynn). Simultaneous to improving cloud physics parameterizations in weather models, I have contributed towards the development of automated aircraft and ground icing forecast applications using the output of models and their explicit prediction of supercooled liquid water together with various surface, radar, and multispectral satellite data to create end-user icing hazard products.

   In addition to cloud physics research, I developed software to ingest, decode, visualize and deliver weather data and graphics to the world wide web. This resulted in multiple, comprehensive and complex websites: NCAR-RAP Realtime Weather Data and ADDS. For the latter, I managed/directed software engineers and coordinated with our collaborators at NOAA-FSL and NCEP-AWC. ADDS is extremely popular with pilots of all abilities, major and minor airline dispatchers, and the military. It is also the showcase for products developed by the FAA's Aviation Weather Research Program.
