Spjeldvik

Spjeldvik is a Professor in the Department of Physics at Weber State University's College of Science since 1985, with expertise in space science, astronomy, computational physics, and theoretical physics. His career spans multiple prestigious roles including NASA Research Principal Investigator (1991-1997), Senior Research Physicist at Boston College (1983-1985), and Principal Software Developer/CEO at Nordmann Research and Development, Inc. (1997-Present).

• Education: Not explicitly mentioned but inferred through professional roles including Post.Doc. at National Academy of Science/NRC (1975-1977)

Research Interests focus on:

• Magnetospheric physics and radiation belts
• Cosmic ray interactions with planetary magnetospheres
• Computational modeling of space particle environments
• Atmospheric radiation phenomena (X-rays, gamma rays, neutrons)
• Space weather impacts on terrestrial systems
• Plasma dynamics in planetary magnetic fields

Recent Publications (2013-2022) demonstrate consistent work in:

• Magnetospheric antiproton distributions
• Planetary radiation belt modeling
• Heavy ion dynamics across solar system bodies
• Atmospheric radiation monitoring in tropical regions
• Space weather impacts on particle acceleration
• Cosmic ray induced radiation phenomena

Awards:

• Post.Doc. Awardee, National Academy of Science/NRC

Professional Collaborations span 20+ international institutions including NASA, RIKEN, Boston University, University of Bergen, and Brazilian space agencies. His work bridges theoretical physics, computational modeling, and space environment monitoring with continuous engagement in spacecraft data analysis (POLAR, OHZORA, CORONAS-F) since the 1980s.
