Frank Witmer is a computational geographer who conducts research in violent conflict and human-environment interactions using spatial statistical methods, remote sensing data, and simulation. He also uses immersive visualization technology in the Planetarium and Visualization Theater (PVT) to study the effects of environmental changes on salmon and Alaska fisheries. He currently teaches classes in both the Computer Science and Geomatics departments at UAA.

Research Interests

  1. Human-environment geography, with an emphasis on quantifying how human activity (e.g. war, population growth, urbanization) affects environmental conditions (e.g. land use, deforestation, climate) at local and regional scales.
  2. Immersive visualization of environmental changes at multiple scales
  3. Remote sensing, especially as applied to war and land-use/land-cover change detection
  4. Development of methods from spatial statistics, GIScience, and remote sensing for analyzing sociodemographic and environmental change data, including the location and diffusion of point events (e.g. violence, crime)
