Research Interests

The goal of my research is to develop computer vision, machine learning, and graphics techniques to understand, analyze, and visualize how the world changes over time. Much of the current work in my research group focuses on three ongoing lines of work:

  • Identifying unusual frames and analyzing long-term changes in live-streaming webcams.
  • Using per-pixel features from deep neural networks to improve lower-level vision and image processing tasks like image segmentation, seam carving, and graph cuts.
  • Analyzing satellite and drone imagery to investigate legibility of international borders (with applications in Political Science) and identify and count birds, nests, and woody debris in stream ecosystems (with applications in Ecology).


I am always looking for motivated students to get involved in my research. If you are a current WWU undergraduate or MS student interested in working with me, send me email or stop by my office.
