Blake J. Allen, M.S.
Blake received bachelors degrees in Physics and Chemistry from Pittsburg State University in Pittsburg, KS, and then went on to complete a Masters in Meteorology at the University of Oklahoma in 2014. Before joining Metstat, Blake worked during and after graduate school in the storm electrification group at the National Severe Storms Laboratory. There he studied various aspects of thunderstorms, especially their microphysical properties and lightning production. His thesis work focused on leveraging satellite-borne lightning data to improve the representation of thunderstorms in numerical weather prediction models that use ensemble data assimilation. He also worked on a project that modeled the atmospheric transport of nitric oxides produced by lightning, another project that involved statistical comparisons of radar data, and a project that analyzed the fractal characteristics of observed and simulated lightning. Between numerical model development, analysis and processing of data, and visualization of data, Blake's past work has given him significant experience programming in Python, FORTRAN, and other languages, as well as experience working with various scientific data formats. While at NSSL, Blake also enjoyed helping with various field campaigns. He helped collect balloon-borne storm electrification observations during an NSSL project, mobile radar data during the 2010 VORTEX2 and 2012 DC3 projects, and both mobile mesonet and balloon-borne observations during the 2015 PECAN project. Outside of work, he enjoys hiking and other outdoor activities as well as music and movies.
Shauna Bokn, B.S.
Shauna received a Bachelor of Science in Applied Mathematics with a concentration in Meteorology from the Metropolitan State University of Denver in 2017. Before she joined MetStat, Shauna was a Student Assistant at the National Center for Atmospheric Research (NCAR) where she worked with the Federal Aviation Administration (FAA) to test the accuracy of a present weather sensor to be placed at all Automated Service Observing System (ASOS) stations across the United States. Some of her undergraduate research includes numerical modeling of severe convective storms and the tornado siren policy in Oklahoma City. Her current research involves examining the relationship between mid-latitude sinuosity and arctic amplification (AA) and how these two processes might be affecting weather patterns, causing more extreme weather events in the Northern Hemisphere. With her strong background in mathematics and meteorology, she wants to effectively apply her knowledge and experience in both areas with her position at MetStat. In her free time, Shauna enjoys being outdoors, reading, and spending time with friends and family.
