  • Mar 2015 - Mar 2022

  As System Development Software Engineer for the Space Systems Analysis and Test Group within the Space Systems and Technology Division at MIT-LL, designed, developed, implemented, and ran multiple software tools with enhanced capabilities for use on workstations and Lincoln Laboratory Supercomputing Center (LLSC) grid systems in support of group’s research activities within multiple projects. Provided codes and advised on their usage to other groups and divisions upon request. Reviewed, tested, evaluated, and debugged programs from various sources and vendors. Developed, maintained, and ran suite of codes that enable user-friendly means of running multiple standard ionosphere models and supporting analysis tools to generate deliverable products. Develop automated batch processing code for computing model ionosphere grids and determining homing solutions of HF rays between grids of sources and grids of targets and their returns to grid of receivers. As member of several HF projects, ran ionosphere models and ray-tracing codes to support data collection campaigns and simulations. Wrote and used additional analysis codes. Retrieved and incorporated GPS RINEX and other external data products for improved modeled results. Investigated and evaluated HF link networks, OTHR, and prototype systems performances. Kept current the inventory of multiple vendor models and analytical codes (e.g., IGRF; IRI, GPSII, TIEGCM; TraceRay, PHaRLAP). Built and maintained multiple in-house databases of solar and geophysical parameters. Assisted in setting up an automated near-Real Time system of modeling network of active HF links. Generated and used several large databases of multiple model ionosphere grids spanning 21 years for statistical HF links studies. Provided consultation as subject matter expert on areas related to space sciences and technology. Show less

• Staff Scientist

  • Aug 1992 - Apr 2014

  Provided support for the research efforts at AER, including contractual work for Air Force Research Laboratory (AFRL), and for National Oceanic and Atmospheric Administration (NOAA). Did sophisticated analytical and computational studies; research and operational programming; project proposal development; data processing, analysis and visualization; theoretical derivations and modeling efforts. Was team member of AER GOES-R Ground Segment Science Engineering group for Harris/NOAA. Provided proxy data and in-depth analysis for the Solar Ultraviolet Imager and the Advanced Baseline Imager. Evaluated, assessed, and assured conformity and performance of research codes with their converted operational algorithms such as Hurricane Intensity Estimation. Was Technical Lead for several SBIR projects and other short-term but critical programs. Areas of significant contributions and expertise: - Atmospheric phenomenology, climatology, neutral density modeling, and radiance transmission. - IR radiance scenes simulation and nowcast/forecast of space weather effects on DoD systems. - Mission simulation and support. - Electromagnetic scattering and propagation. - Resident Space Object (RSO) detectability and characterization. - Space Situational Awareness. - Satellite drag and ephemeris. - Space-based sensor data processing and analysis. Represented AER to the scientific and technical communities through peer reviewed publications, technical reports, and at professional conferences. Presented 11 talks and 4 posters at key technical conferences. Lead author of 15 Technical Reports, 1 conference proceedings article, and 1 journal article. Space Weather Division Employee of the Year in 2007. Show less



Radex, Inc

• Research Analyst

  • Aug 1992 - Jun 2004

  Worked as contractor for AFRL/Hanscom AFB (MA) 1992-2004 until Radex was acquired by AER. Was a long-term significant key member of the AFRL Midcourse Space Experiment (MSX) satellite Earthlimb group. Duties included satellite data collection planning and post-analysis; orbit determination with emphasis on atmospheric effects and drag; plasma and atmospherics physics studies; GPS signal processing; and space and geophysical environmental studies for several projects.
